A network has been created that predicts the erosion volume based on hydraulic boundary conditions and a number of cross-shore profile indicators. Field measurement data along a large part of the Dutch coast has been used to train the network. Corresponding storm impact on the dunes was calculated with an empirical dune erosion model named duros+. Comparison between the Bayesian Network predictions and the original duros+ results, here considered as observations, results in a skill up to 0.88, provided that the training data covers the range of predictions. Hence, the predictions from a deterministic model (duros+) can be captured in a probabilistic model (Bayesian Network) such that both the process knowledge and uncertainties can be included in impact and vulnerability assessments.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Coastal Engineering 2012: Proceedings of the 33rd International Conference on Coastal Engineering","largerWorkSubtype":{"id":12,"text":"Conference publication"},"conferenceTitle":"33rd International Conference on Coastal Engineering","conferenceLocation":"Santander, Spain","language":"English","publisher":"Coastal Engineering Research Council","doi":"10.9753/icce.v33.management.4","usgsCitation":"den Heijer, C., Knipping, D.T., Plant, N.G., van Thiel de Vries, J.S., Baart, F., and van Gelder, P.H., 2012, Impact assessment of extreme storm events using a Bayesian network, <i>in</i> Coastal Engineering 2012: Proceedings of the 33rd International Conference on Coastal Engineering, no. 33, Santander, Spain, 15 p., https://doi.org/10.9753/icce.v33.management.4.","productDescription":"15 p.","numberOfPages":"15","ipdsId":"IP-041009","costCenters":[{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":474597,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.9753/icce.v33.management.4","text":"Publisher Index Page"},{"id":294554,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294553,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.9753/icce.v33.management.4"}],"issue":"33","noUsgsAuthors":false,"publicationDate":"2012-10-25","publicationStatus":"PW","scienceBaseUri":"54252eb8e4b0e641df8a7032","contributors":{"authors":[{"text":"den Heijer, C.","contributorId":52904,"corporation":false,"usgs":true,"family":"den Heijer","given":"C.","email":"","affiliations":[],"preferred":false,"id":496794,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Knipping, Dirk T.J.A.","contributorId":92598,"corporation":false,"usgs":true,"family":"Knipping","given":"Dirk","email":"","middleInitial":"T.J.A.","affiliations":[],"preferred":false,"id":496795,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Plant, Nathaniel G. 0000-0002-5703-5672 nplant@usgs.gov","orcid":"https://orcid.org/0000-0002-5703-5672","contributorId":3503,"corporation":false,"usgs":true,"family":"Plant","given":"Nathaniel","email":"nplant@usgs.gov","middleInitial":"G.","affiliations":[{"id":508,"text":"Office of the AD Hazards","active":true,"usgs":true},{"id":574,"text":"St. Petersburg Coastal and Marine Science Center","active":true,"usgs":true}],"preferred":true,"id":496791,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"van Thiel de Vries, Jaap S.

Of particular interest is the stratigraphic record of a ?5 km thick layered rock sequence exposed on the slopes of Aeolis Mons (also known as Mount Sharp). The instrument consists of three parts, a camera head mounted on the turret at the end of a robotic arm, an electronics and data storage assembly located inside the rover body, and a calibration target mounted on the robotic arm shoulder azimuth actuator housing. MAHLI can acquire in-focus images at working distances from ?2.1 cm to infinity. At the minimum working distance, image pixel scale is ?14 &mu;m per pixel and very coarse silt grains can be resolved. At the working distance of the Mars Exploration Rover Microscopic Imager cameras aboard Spirit and Opportunity, MAHLI?s resolution is comparable at ?30 &mu;m per pixel. Onboard capabilities include autofocus, auto-exposure, sub-framing, video imaging, Bayer pattern color interpolation, lossy and lossless compression, focus merging of up to 8 focus stack images, white light and longwave ultraviolet (365 nm) illumination of nearby subjects, and 8 gigabytes of non-volatile memory data storage.","language":"English","publisher":"Springer","doi":"10.1007/s11214-012-9910-4","usgsCitation":"Edgett, K., Yingst, R.A., Ravine, M.A., Caplinger, M.A., Maki, J.N., Ghaemi, F., Schaffner, J.A., Bell, J.F., Edwards, L.J., Herkenhoff, K.E., Heydari, E., Kah, L., Lemmon, M.T., Minitti, M.E., Olson, T.S., Parker, T.J., Rowland, S.K., Schieber, J., Sullivan, R.J., Sumner, D.Y., Thomas, P.C., Jensen, E.H., Simmonds, J.J., Sengstacken, A.J., Wilson, R.G., and Goetz, W., 2012, Curiosity's Mars Hand Lens Imager (MAHLI) investigation: Space Science Reviews, v. 170, no. 1-4, p. 259-317, https://doi.org/10.1007/s11214-012-9910-4.","productDescription":"59 p.","startPage":"259","endPage":"317","costCenters":[{"id":131,"text":"Astrogeology Science Center","active":true,"usgs":true}],"links":[{"id":474598,"rank":1,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1007/s11214-012-9910-4","text":"Publisher Index Page"},{"id":261793,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"otherGeospatial":"Mars","volume":"170","issue":"1-4","noUsgsAuthors":false,"publicationDate":"2012-07-05","publicationStatus":"PW","scienceBaseUri":"5059fd0de4b0c8380cd4e5ea","contributors":{"authors":[{"text":"Edgett, Kenneth S.","contributorId":12736,"corporation":false,"usgs":true,"family":"Edgett","given":"Kenneth S.","affiliations":[],"preferred":false,"id":466037,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Yingst, R.

Published paleoproxy and modeling studies suggest that prior to ∼8000 cal years BP, the NAM affected a broader region than today, extending westward into the Mojave Desert of California. Holocene proxy SST records from the Gulf of California (GoC) and the adjacent Pacific provide constraints for this changing NAM climatology. Prior to ∼8000 cal years BP, lower GoC SSTs would not have fueled northward surges of tropical moisture up the GoC, which presently contribute most of the monsoon precipitation to the western NAM region. During the early Holocene, the North Pacific High was further north and SSTs in the California Current off Baja California were warmer, allowing monsoonal moisture flow from the subtropical Pacific to take a more direct, northwesterly trajectory into an expanded area of the southwestern U.S. west of 114°W. A new upwelling record off southwest Baja California reveals that enhanced upwelling in the California Current beginning at ∼7500 cal year BP may have triggered a change in NAM climatology, focusing the geographic expression of NAM in the southwest USA into its modern core region east of ∼114°W, in Arizona and New Mexico. Holocene proxy precipitation records from the southwestern U.S. and northwestern Mexico, including lakes, vegetation/pollen, and caves are reviewed and found to be largely supportive of this hypothesis of changing Holocene NAM climatology.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Paleoceanography","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/2011PA002235","usgsCitation":"Barron, J.A., Metcalfe, S.E., and Addison, J.A., 2012, Response of the North American monsoon to regional changes in ocean surface temperature: Paleoceanography, v. 27, no. 3, 17 p., https://doi.org/10.1029/2011PA002235.","productDescription":"17 p.","numberOfPages":"17","ipdsId":"IP-020653","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":474599,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2011pa002235","text":"Publisher Index Page"},{"id":277405,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277388,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011PA002235"}],"country":"Mexico;United States","state":"Arizona;Colorado;New Mexico;Texas;Utah","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -120.0,20.0 ], [ -120.0,40.0 ], [ -100.0,40.0 ], [ -100.0,20.0 ], [ -120.0,20.0 ] ] ] } } ] }","volume":"27","issue":"3","noUsgsAuthors":false,"publicationDate":"2012-07-25","publicationStatus":"PW","scienceBaseUri":"522af96de4b08fd0132e7a09","contributors":{"authors":[{"text":"Barron, John A. 0000-0002-9309-1145 jbarron@usgs.gov","orcid":"https://orcid.org/0000-0002-9309-1145","contributorId":2222,"corporation":false,"usgs":true,"family":"Barron","given":"John","email":"jbarron@usgs.gov","middleInitial":"A.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":483657,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Metcalfe, Sarah E.","contributorId":103555,"corporation":false,"usgs":true,"family":"Metcalfe","given":"Sarah","email":"","middleInitial":"E.","affiliations":[],"preferred":false,"id":483659,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Addison, Jason A. 0000-0003-2416-9743 jaddison@usgs.gov","orcid":"https://orcid.org/0000-0003-2416-9743","contributorId":4192,"corporation":false,"usgs":true,"family":"Addison","given":"Jason","email":"jaddison@usgs.gov","middleInitial":"A.","affiliations":[{"id":114,"text":"Alaska Science Center","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":483658,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Although maps are traditionally created through field surveys, remote sensing allows an extraordinary view of active lava flows while avoiding the difficulties of mapping on location. Synthetic aperture radar (SAR) imagery, in particular, can detect changes in a flow field by comparing two images collected at different times with SAR coherence. New lava flows radically alter the scattering properties of the surface, making the radar signal decorrelated in SAR coherence images. We describe a new technique, SAR Coherence Mapping (SCM), to map lava flows automatically from coherence images independent of look angle or satellite path. We use this approach to map lava flow emplacement during the Pu‘u ‘Ō‘ō-Kupaianaha eruption at Kīlauea, Hawai‘i. The resulting flow maps correspond well with field mapping and better resolve the internal structure of surface flows, as well as the locations of active flow paths. However, the SCM technique is only moderately successful at mapping flows that enter vegetation, which is also often decorrelated between successive SAR images. Along with measurements of planform morphology, we are able to show that the length of time a flow stays decorrelated after initial emplacement is linearly related to the flow thickness. Finally, we use interferograms obtained after flow surfaces become correlated to show that persistent decorrelation is caused by post-emplacement flow subsidence.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochemistry, Geophysics, Geosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"AGU and the Geochemical Society","doi":"10.1029/2011GC004016","usgsCitation":"Dietterich, H.R., Poland, M., Schmidt, D., Cashman, K., Sherrod, D.R., and Espinosa, A., 2012, Tracking lava flow emplacement on the east rift zone of Kilauea, Hawai’i with synthetic aperture radar (SAR) coherence: Geochemistry, Geophysics, Geosystems, v. 13, no. 5, 17 p., https://doi.org/10.1029/2011GC004016.","productDescription":"17 p.","ipdsId":"IP-035895","costCenters":[{"id":157,"text":"Cascades Volcano Observatory","active":false,"usgs":true},{"id":336,"text":"Hawaiian Volcano Observatory","active":false,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true}],"links":[{"id":474600,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2011gc004016","text":"Publisher Index Page"},{"id":274781,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":274780,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2011GC004016"}],"country":"United States","state":"Hawai'i","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -156.062,18.9108 ], [ -156.062,20.2686 ], [ -154.8065,20.2686 ], [ -154.8065,18.9108 ], [ -156.062,18.9108 ] ] ] } } ] }","volume":"13","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"51dd30efe4b0f72b44719ccc","contributors":{"authors":[{"text":"Dietterich, Hannah R.","contributorId":11920,"corporation":false,"usgs":true,"family":"Dietterich","given":"Hannah","email":"","middleInitial":"R.","affiliations":[],"preferred":false,"id":480385,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Poland, Michael P. 0000-0001-5240-6123 mpoland@usgs.gov","orcid":"https://orcid.org/0000-0001-5240-6123","contributorId":635,"corporation":false,"usgs":true,"family":"Poland","given":"Michael P.","email":"mpoland@usgs.gov","affiliations":[{"id":336,"text":"Hawaiian Volcano Observatory","active":false,"usgs":true}],"preferred":false,"id":480388,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Schmidt, David","contributorId":7596,"corporation":false,"usgs":true,"family":"Schmidt","given":"David","affiliations":[],"preferred":false,"id":480384,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Cashman, Katharine V.","contributorId":40097,"corporation":false,"usgs":false,"family":"Cashman","given":"Katharine V.","affiliations":[],"preferred":false,"id":480386,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Sherrod, David R. 0000-0001-9460-0434 dsherrod@usgs.gov","orcid":"https://orcid.org/0000-0001-9460-0434","contributorId":527,"corporation":false,"usgs":true,"family":"Sherrod","given":"David","email":"dsherrod@usgs.gov","middleInitial":"R.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":480383,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Espinosa, Arkin Tapia","contributorId":64977,"corporation":false,"usgs":true,"family":"Espinosa","given":"Arkin Tapia","affiliations":[],"preferred":false,"id":480387,"contributorType":{"id":1,"text":"Authors"},"rank":6}]}}

The last detections of 'Oma'o on the leeward side of the island were in woodland habitat on the western flank of Mauna Loa in 1978. 'Oma'o were detected in woodland habitat in relatively low densities during a 2010 forest bird survey of Hawai'i Volcanoes National Park. The source of the population is unknown. It is probable they originated from a documented but unsurveyed population of 'Oma'o in scrub alpine lava. Alternatively, the birds may have persisted undetected for nearly 35 years, or expanded from windward mesic forests on southeast Mauna Loa. There is no evidence 'Oma'o recolonized the wet mesic forests of leeward Mauna Loa. The 'Oma'o can occupy diverse native habitats compared to other species in the Hawai'i Myadestes genus, of which most species are now extinct. The connectivity of each population is not understood but we assume there are significant geographic, physiological, and behavioral barriers for scrub alpine and wet mesic forest populations. The expansion of 'Oma'o to leeward woodlands is encouraging as the species is Hawai'i Island's last native frugivore capable of dispersing small and medium sized seeds of rare angiosperms, and could have an important role in re-establishing ecosystem function.&nbsp;</span></p>","language":"English","publisher":"Wilson Ornithological Society","doi":"10.1676/1559-4491-124.4.675","usgsCitation":"Judge, S.W., Gaudioso, J.M., Gorresen, P.M., and Camp, R., 2012, Reoccurrence of 'Ōma'o in leeward woodland habitat and their distribution in alpine habitat on Hawai'i island: Wilson Journal of Ornithology, v. 124, no. 4, p. 675-681, https://doi.org/10.1676/1559-4491-124.4.675.","productDescription":"7 p.","startPage":"675","endPage":"681","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-038884","costCenters":[{"id":521,"text":"Pacific Island Ecosystems Research Center","active":false,"usgs":true}],"links":[{"id":381924,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Hawaii","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -160.27,18.91 ], [ -160.27,22.33 ], [ -154.81,22.33 ], [ -154.81,18.91 ], [ -160.27,18.91 ] ] ] } } ] }","volume":"124","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"527cc493e4b0850ea050ceb0","contributors":{"authors":[{"text":"Judge, Seth W.","contributorId":8718,"corporation":false,"usgs":true,"family":"Judge","given":"Seth","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":485158,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gaudioso, Jacqueline M.","contributorId":12316,"corporation":false,"usgs":true,"family":"Gaudioso","given":"Jacqueline","email":"","middleInitial":"M.","affiliations":[],"preferred":false,"id":485159,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Gorresen, P.

Engineering constraints important to the selection included: (1) latitude (&plusmn;30&deg;) for thermal management of the rover and instruments, (2) elevation (<-1 km) for sufficient atmosphere to slow the spacecraft, (3) relief of <100-130 m at baselines of 1-1000 m for control authority and sufficient fuel during powered descent, (4) slopes of <30&deg; at baselines of 2-5 m for rover stability at touchdown, (5) moderate rock abundance to avoid impacting the belly pan during touchdown, and (6) a radar-reflective, load-bearing, and trafficable surface that is safe for landing and roving and not dominated by fine-grained dust. Science criteria important for the selection include the ability to assess past habitable environments, which include diversity, context, and biosignature (including organics) preservation. Sites were evaluated in detail using targeted data from instruments on all active orbiters, and especially Mars Reconnaissance Orbiter. All of the final four sites have layered sedimentary rocks with spectral evidence for phyllosilicates that clearly address the science objectives of the mission. Sophisticated entry, descent and landing simulations that include detailed information on all of the engineering constraints indicate all of the final four sites are safe for landing. Evaluation of the traversabilty of the landing sites and target “go to” areas outside of the ellipse using slope and material properties information indicates that all are trafficable and “go to” sites can be accessed within the lifetime of the mission. In the final selection, Gale crater was favored over Eberswalde based on its greater diversity and potential

However, new sensitive high-resolution ion microprobe (SHRIMP) U-Pb ages for zircon from gabbro xenoliths from a late Pleistocene pyroclastic deposit are dominated by much older, ca. 310 Ma Pennsylvanian and ca. 1865 Ma Paleoproterozoic grains. Zircon age distributions and trace-element concentrations indicate that the ca. 310 Ma zircons date gabbroic intrusive rocks, and the ca. 1865 Ma zircons also are likely from igneous rocks in or beneath Peninsular terrane basement. The trace-element data imply that four of five Cretaceous–Paleocene zircons, and Pennsylvanian low-U, low-Th zircons in one sample, grew from metamorphic or hydrothermal fluids. Textural evidence of xenocrysts and a dominant population of ca. 1865 Ma zircon in juvenile crystal-rich andesite from the same pyroclastic deposit show that this basement has been assimilated by Redoubt magma. Equilibration temperatures and oxygen fugacities indicated by Fe-Ti–oxide minerals in the gabbros and crystal-rich andesite suggest sources near the margins of the Redoubt magmatic system, most likely in the magma accumulation and storage region currently outlined by seismicity and magma petrology at ∼4–10 km below sea level. Additionally, a partially melted gabbro from the 1990 eruption contains zircon with U-Pb ages between ca. 620 Ma and ca. 1705 Ma, as well as one zircon with a U-Th disequilibrium model age of 0 ka. The zircon ages demonstrate that Pennsylvanian, and probably Paleoproterozoic, igneous rocks exist in, or possibly beneath, Peninsular terrane basement. Discovery of Pennsylvanian gabbro similar in age to Skolai arc plutons 500 km to the northeast indicates that the Peninsular terrane, along with the Wrangellia and Alexander terranes, has been part of the Wrangellia composite terrane since at least Pennsylvanian time. Moreover, the zircon data suggest that a Paleoproterozoic continental fragment may be present in the mid-to-upper crust in southern Alaska.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geological Society of America Bulletin","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/B30439.1","usgsCitation":"Bacon, C.R., Vazquez, J.A., and Wooden, J., 2012, Peninsular terrane basement ages recorded by Paleozoic and Paleoproterozoic zircon in gabbro xenoliths and andesite from Redoubt volcano, Alaska: Geological Society of America Bulletin, v. 124, no. 1-2, p. 24-34, https://doi.org/10.1130/B30439.1.","productDescription":"11 p.","startPage":"24","endPage":"34","numberOfPages":"11","ipdsId":"IP-025393","costCenters":[{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":288823,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288802,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/B30439.1"}],"country":"United States","state":"Alaska","otherGeospatial":"Redoubt Volcano","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -154.792,59.774 ], [ -154.792,61.1813 ], [ -150.6941,61.1813 ], [ -150.6941,59.774 ], [ -154.792,59.774 ] ] ] } } ] }","volume":"124","issue":"1-2","noUsgsAuthors":false,"publicationDate":"2011-09-30","publicationStatus":"PW","scienceBaseUri":"53ae77a3e4b0abf75cf2c193","contributors":{"authors":[{"text":"Bacon, Charles R. 0000-0002-2165-5618 cbacon@usgs.gov","orcid":"https://orcid.org/0000-0002-2165-5618","contributorId":2909,"corporation":false,"usgs":true,"family":"Bacon","given":"Charles","email":"cbacon@usgs.gov","middleInitial":"R.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":494934,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Vazquez, Jorge A. 0000-0003-2754-0456 jvazquez@usgs.gov","orcid":"https://orcid.org/0000-0003-2754-0456","contributorId":4458,"corporation":false,"usgs":true,"family":"Vazquez","given":"Jorge","email":"jvazquez@usgs.gov","middleInitial":"A.","affiliations":[{"id":501,"text":"Office of Science Quality and Integrity","active":true,"usgs":true},{"id":617,"text":"Volcano Science Center","active":true,"usgs":true},{"id":615,"text":"Volcano Hazards Program","active":true,"usgs":true},{"id":5056,"text":"Office of the AD Energy and Minerals, and Environmental Health","active":true,"usgs":true}],"preferred":true,"id":494935,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Wooden, Joseph L.","contributorId":32209,"corporation":false,"usgs":true,"family":"Wooden","given":"Joseph L.","affiliations":[],"preferred":false,"id":494936,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

In the last 20,000 years, higher precipitation caused desert lakes to form which have since dried out. Higher glacial precipitation is hypothesized to result from a southward shift of Pacific winter storm tracks. We compared Pacific Ocean data to lake levels from the interior west and found that Great Basin lake high stands are older than coastal wet periods at the same latitude. Westerly storms were not the source of high precipitation. Instead, air masses from the tropical Pacific were transported northward, bringing more precipitation into the Great Basin when coastal California was still dry.  The changing climate during the deglaciation altered precipitation source regions and strongly affected the regional water cycle.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Science","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Association for the Advancement of Science","doi":"10.1126/science.1218390","usgsCitation":"Lyle, M., Heusser, L., Ravelo, C., Yamamoto, M., Barron, J., Diffenbaugh, N.S., Herbert, T., and Andreasen, D., 2012, Out of the tropics: the Pacific, Great Basin lakes, and late Pleistocene water cycle in the western United States: Science, v. 337, p. 1629-1633, https://doi.org/10.1126/science.1218390.","productDescription":"5 p.","startPage":"1629","endPage":"1633","numberOfPages":"5","ipdsId":"IP-039428","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":277400,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277399,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1126/science.1218390"}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.0,30.0 ], [ -124.0,46.0 ], [ -100.0,46.0 ], [ -100.0,30.0 ], [ -124.0,30.0 ] ] ] } } ] }","volume":"337","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"522af967e4b08fd0132e79c1","contributors":{"authors":[{"text":"Lyle, Mitchell","contributorId":99035,"corporation":false,"usgs":true,"family":"Lyle","given":"Mitchell","email":"","affiliations":[],"preferred":false,"id":483643,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Heusser, Linda","contributorId":107181,"corporation":false,"usgs":true,"family":"Heusser","given":"Linda","affiliations":[],"preferred":false,"id":483644,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Ravelo, Christina","contributorId":23057,"corporation":false,"usgs":true,"family":"Ravelo","given":"Christina","email":"","affiliations":[],"preferred":false,"id":483637,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Yamamoto, Masanobu","contributorId":94200,"corporation":false,"usgs":true,"family":"Yamamoto","given":"Masanobu","affiliations":[],"preferred":false,"id":483641,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Barron, John","contributorId":87059,"corporation":false,"usgs":true,"family":"Barron","given":"John","affiliations":[],"preferred":false,"id":483640,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Diffenbaugh, Noah S.","contributorId":94965,"corporation":false,"usgs":true,"family":"Diffenbaugh","given":"Noah","email":"","middleInitial":"S.","affiliations":[],"preferred":false,"id":483642,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Herbert, Timothy","contributorId":33418,"corporation":false,"usgs":true,"family":"Herbert","given":"Timothy","affiliations":[],"preferred":false,"id":483638,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Andreasen, Dyke","contributorId":36041,"corporation":false,"usgs":true,"family":"Andreasen","given":"Dyke","email":"","affiliations":[],"preferred":false,"id":483639,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

This transect covered the main habitats on Savai’i and allowed the team to determine where various reptile species and invasive species occurred across this elevational gradient. No previous reptile research had taken place on Savai’i above the elevation of A’opo Village. Limited sampling was also done around the Forestry Station in Asau. </p><p>The team detected 11 species of lizards during these surveys, which is the majority of species known from Samoa. Noticeably absent was the Pacific black skink (Emoia nigra), which is a dominant element of the Samoan lizard fauna. Also no individuals of the Pacific boa (Candoia bibroni) were detected despite the concentrated effort spent looking for them. One boa was detected by the avifauna team at their Site 1, by the TV tower on a log in a marsh. The invasive house gecko (Hemidactylus frenatus) was also not detected along the main transect, but was the most abundant gecko on buildings in Asau. </p><p>No reptiles were found above 1320 m elevation and most species were found significantly below there. Snakeeyed skinks (Cryptoblepharus poecilopleurus) were detected on Savai’i for the first time at Asau Getaway Resort then above the sawmill on the way to A’opo. Since western Savai’i is so poorly known for reptiles, this is the first time many of these species were recorded from this part of the island. </p><p>Surveys for invasive species detected mammalian species (cats, rats, and pigs) and invertebrate species (Yellow Crazy ants and Big-headed ants). The mammals were found at various sites along the transect, including high elevations. The ants were found at lower elevations along the transect, but the Yellow Crazy ants appear to be irrupting currently on Savai’i and were swamping our traps from sea level to 500 m elevation. </p><p>The low elevation lizard occurrences from sea level to 500 m appeared impaired by the invasive ants. Although habitat looked good in many places along the transect, certain species were rare or absent when the invasive ants were present, e.g. the Samoan skink (Emoia samoensis) which only occurred at elevations higher than the ants, whereas elsewhere in its range it occurs down to sea level. </p><p>Currently the uplands over 500 m are free of invasive ants. We know from Hawai’i that invasive ants occur to over 2,000 m elevation and are ecologically very destructive to native flora and fauna. There is an immediate need to try to stop this upward ant invasion to protect this at-risk ecosystem, and to study the intact system now prior to an invasion. </p>","largerWorkType":{"id":18,"text":"Report"},"largerWorkTitle":"Rapid biodiversity assessment of Upland Savai'i, Samoa","largerWorkSubtype":{"id":9,"text":"Other Report"},"language":"English","publisher":"Secretariat of the Pacific Regional Environment Programme (SPREP)","usgsCitation":"Fisher, R.N., and Uili, M., 2012, Report on the reptiles of Upland Savai’i , 23 p.","productDescription":"23 p.","startPage":"61","endPage":"83","ipdsId":"IP-070139","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":359573,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":356098,"type":{"id":11,"text":"Document"},"url":"https://www.cepf.net/sites/default/files/59745_technicalreport_rap_upland_savaii.pdf","linkFileType":{"id":1,"text":"pdf"}}],"publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5bf3d9f3e4b045bfcae0c9c1","contributors":{"editors":[{"text":"Atherton, James","contributorId":210704,"corporation":false,"usgs":false,"family":"Atherton","given":"James","email":"","affiliations":[],"preferred":false,"id":751502,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Jefferies, Bruce","contributorId":210705,"corporation":false,"usgs":false,"family":"Jefferies","given":"Bruce","email":"","affiliations":[],"preferred":false,"id":751503,"contributorType":{"id":2,"text":"Editors"},"rank":2}],"authors":[{"text":"Fisher, Robert N. 0000-0002-2956-3240 rfisher@usgs.gov","orcid":"https://orcid.org/0000-0002-2956-3240","contributorId":1529,"corporation":false,"usgs":true,"family":"Fisher","given":"Robert","email":"rfisher@usgs.gov","middleInitial":"N.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":741321,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Uili, Moeumu","contributorId":206630,"corporation":false,"usgs":false,"family":"Uili","given":"Moeumu","email":"","affiliations":[{"id":37360,"text":"Division of Environment and Conservation Ministry of Natural Resources and Environment, Samoa","active":true,"usgs":false}],"preferred":false,"id":741322,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

The methods apply with little or no modification, however, to formal estimates of population size, other temporal units (e.g. a month), to spatial or other dimensions such as elevation or a north–south gradient, and to other quantities such as chemical or geological parameters. The chapter primarily discusses methods for estimating population-wide parameters rather than studying variation in trend within the population, which can be examined using methods presented in other chapters (e.g. Chapters 7, 12, 20). We begin by reviewing key concepts related to trend analysis. We then describe how to evaluate potential bias in trend estimates. An overview of the statistical models used to quantify trends is then presented. We conclude by showing ways to estimate trends using simple methods that can be implemented with spreadsheets.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Design and Analysis of Long-term Ecological Monitoring Studies","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Cambridge University Press","publisherLocation":"Cambridge, UK","doi":"10.1017/CBO9781139022422.016","isbn":"9781139022422","usgsCitation":"Bart, J., and Beyer, H.L., 2012, Analysis options for estimating status and trends in long-term monitoring, chap. <i>of</i> Design and Analysis of Long-term Ecological Monitoring Studies, p. 253-278, https://doi.org/10.1017/CBO9781139022422.016.","productDescription":"26 p.","startPage":"253","endPage":"278","numberOfPages":"26","ipdsId":"IP-029100","costCenters":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"links":[{"id":277107,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277106,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1017/CBO9781139022422.016"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"521f1be2e4b0f8bf2b0760ce","contributors":{"authors":[{"text":"Bart, Jonathan jon_bart@usgs.gov","contributorId":57025,"corporation":false,"usgs":true,"family":"Bart","given":"Jonathan","email":"jon_bart@usgs.gov","affiliations":[{"id":290,"text":"Forest and Rangeland Ecosystem Science Center","active":false,"usgs":true}],"preferred":false,"id":480303,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Beyer, Hawthorne L.","contributorId":99871,"corporation":false,"usgs":true,"family":"Beyer","given":"Hawthorne","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":480304,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

After controlling for anthropogenic inputs and other landscape factors affecting nutrient transport-such as runoff, precipitation, slope, number of reservoirs, irrigated area, and area with subsurface tile drains-the relations between export and the area in the Conservation Reserve Program (CRP) (N) and conservation tillage (P) were positive. Additional interaction terms indicated that the relations between export and the area in conservation tillage (N) and the CRP (P) progressed from being clearly positive when soil erodibility was low or moderate, to being close to zero when soil erodibility was higher, to possibly being slightly negative only at the 90th to 95th percentile of soil erodibility values. Possible explanations for the increase in nutrient export with increased area in management practices include greater transport of soluble nutrients from areas in conservation tillage; lagged response of stream quality to implementation of management practices because of nitrogen transport in groundwater, time for vegetative cover to mature, and/or prior accumulation of P in soils; or limitations in the management practice and stream monitoring data sets. If lags are occurring, current nutrient export from agricultural watersheds may still be reflecting the influence of agricultural land-use practices that were in place before the implementation of these management practices.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Environmental Quality","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Society of Agronomy","doi":"10.2134/jeq2012.0073","usgsCitation":"Sprague, L.A., and Gronberg, J., 2012, Relating management practices and nutrient export in agricultural watersheds of the United States: Journal of Environmental Quality, v. 41, no. 6, p. 1939-1950, https://doi.org/10.2134/jeq2012.0073.","productDescription":"12 p.","startPage":"1939","endPage":"1950","numberOfPages":"12","ipdsId":"IP-036746","costCenters":[{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true}],"links":[{"id":276041,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":276040,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2134/jeq2012.0073"}],"country":"United States","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -124.8,24.5 ], [ -124.8,49.383333 ], [ -66.95,49.383333 ], [ -66.95,24.5 ], [ -124.8,24.5 ] ] ] } } ] }","volume":"41","issue":"6","noUsgsAuthors":false,"publicationDate":"2012-11-01","publicationStatus":"PW","scienceBaseUri":"5200c967e4b009d47a4c23c5","contributors":{"authors":[{"text":"Sprague, Lori A. 0000-0003-2832-6662 lsprague@usgs.gov","orcid":"https://orcid.org/0000-0003-2832-6662","contributorId":726,"corporation":false,"usgs":true,"family":"Sprague","given":"Lori","email":"lsprague@usgs.gov","middleInitial":"A.","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true},{"id":509,"text":"Office of the Associate Director for Water","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":463109,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Gronberg, Jo Ann M.","contributorId":18342,"corporation":false,"usgs":true,"family":"Gronberg","given":"Jo Ann M.","affiliations":[],"preferred":false,"id":463110,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Other indices such as the Vegetation Health Index (VHI) were also developed during this time period, and applied to AVHRR NDVI and brightness temperature data for routine global monitoring of drought conditions. These early efforts demonstrated the unique perspective that global imagers such as AVHRR could provide for operational drought monitoring through their near-daily, global observations of Earth's land surface. However, the advancement of satellite remote sensing of drought was limited by the relatively few spectral bands of operational global sensors such as AVHRR, along with a relatively short period of observational record. Remote sensing advancements are of paramount importance given the increasing demand for tools that can provide accurate, timely, and integrated information on drought conditions to facilitate proactive decision making (NIDIS, 2007). Satellite-based approaches are key to addressing significant gaps in the spatial and temporal coverage of current surface station instrument networks providing key moisture observations (e.g., rainfall, snow, soil moisture, ground water, and ET) over the United States and globally (NIDIS, 2007). Improved monitoring capabilities will be particularly important given increases in spatial extent, intensity, and duration of drought events observed in some regions of the world, as reported in the International Panel on Climate Change (IPCC) report (IPCC, 2007). The risk of drought is anticipated to further increase in some regions in response to climatic changes in the hydrologic cycle related to evaporation, precipitation, air temperature, and snow cover (Burke et al., 2006; IPCC, 2007; USGCRP, 2009). Numerous national, regional, and global efforts such as the Famine and Early Warning System (FEWS), National Integrated Drought Information System (NIDIS), and Group on Earth Observations (GEO), as well as the establishment of regional drought centers (e.g., European Drought Observatory) and geospatial visualization and monitoring systems (e.g, NASA SERVIR) have been undertaken to improve drought monitoring and early warning systems throughout the world. The suite of innovative remote sensing tools that have recently emerged will be looked upon to fill important data and knowledge gaps (NIDIS, 2007; NRC, 2007) to address a wide range of drought-related issues including food security, water scarcity, and human health.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Remote sensing of drought: innovative monitoring approaches","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"CRC Press","publisherLocation":"Boca Raton, FL","doi":"10.1201/b11863-23","usgsCitation":"Wardlow, B.D., Anderson, M.C., Sheffield, J., Doorn, B., Verdin, J., Zhan, X., and Rodell, M., 2012, Future opportunities and challenges in remote sensing of drought, chap. <i>of</i> Remote sensing of drought: innovative monitoring approaches, p. 389-410, https://doi.org/10.1201/b11863-23.","productDescription":"22 p.","startPage":"389","endPage":"410","ipdsId":"IP-031383","costCenters":[{"id":222,"text":"Earth Resources Observation and Science (EROS) Center","active":true,"usgs":true}],"links":[{"id":474601,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/2060/20120003712","text":"External Repository"},{"id":276693,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"520f49e1e4b0fc50304bc4b4","contributors":{"editors":[{"text":"Wardlow, Brian D.","contributorId":75845,"corporation":false,"usgs":true,"family":"Wardlow","given":"Brian","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":509193,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Anderson, Martha C.","contributorId":96579,"corporation":false,"usgs":false,"family":"Anderson","given":"Martha","email":"","middleInitial":"C.","affiliations":[{"id":6622,"text":"US Department of Agriculture","active":true,"usgs":false}],"preferred":false,"id":509194,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Verdin, James P. 0000-0003-0238-9657 verdin@usgs.gov","orcid":"https://orcid.org/0000-0003-0238-9657","contributorId":720,"corporation":false,"usgs":true,"family":"Verdin","given":"James","email":"verdin@usgs.gov","middleInitial":"P.","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":false,"id":509192,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"Wardlow, Brian D.","contributorId":75845,"corporation":false,"usgs":true,"family":"Wardlow","given":"Brian","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":473339,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Anderson, Martha C.","contributorId":96579,"corporation":false,"usgs":false,"family":"Anderson","given":"Martha","email":"","middleInitial":"C.","affiliations":[{"id":6622,"text":"US Department of Agriculture","active":true,"usgs":false}],"preferred":false,"id":473341,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Sheffield, Justin","contributorId":69462,"corporation":false,"usgs":true,"family":"Sheffield","given":"Justin","affiliations":[],"preferred":false,"id":473337,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Doorn, Brad","contributorId":74288,"corporation":false,"usgs":true,"family":"Doorn","given":"Brad","email":"","affiliations":[],"preferred":false,"id":473338,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Verdin, James 0000-0003-0238-9657 verdin@usgs.gov","orcid":"https://orcid.org/0000-0003-0238-9657","contributorId":145830,"corporation":false,"usgs":true,"family":"Verdin","given":"James","email":"verdin@usgs.gov","affiliations":[{"id":223,"text":"Earth Resources Observation and Science (EROS) Center (Geography)","active":false,"usgs":true}],"preferred":true,"id":839357,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Zhan, Xiwu","contributorId":41323,"corporation":false,"usgs":true,"family":"Zhan","given":"Xiwu","email":"","affiliations":[],"preferred":false,"id":473336,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Rodell, Matt","contributorId":93806,"corporation":false,"usgs":true,"family":"Rodell","given":"Matt","email":"","affiliations":[],"preferred":false,"id":473340,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Almost no original paleobotanical work has been done on this assemblage since the pioneering treatments published by E.W. Berry, in the 1920’s and the precise age has not been settled. Nevertheless, the flora has been regarded as an important focal point in understanding the vegetational, orogenic and climatic history of northern South America, and in recent literature has been assumed to be early Eocene. In order to tighten the age assignment, which has varied from early Eocene to early Oligocene in the opinions of different authors, we revisited the Belén site, measured the stratigraphic section, and processed the fruit and seed-containing sediment for age-diagnostic microfossils. Although pollen and foraminifera were not recovered, the sediment is rich in diatoms. The diatom assemblage includes Lisitzinia ornata and Rocella vigilans among others, indicating a latest early Oligocene age (~30-28.5 Ma) for these deeper marine sediments that we infer to have been subsequently reworked into the Belén environment . This association leads us to consider the Belén flora, to be late Oligocene in age as is also consistent with its placement in the Mancora Formation. We also reevaluate the botanical identifications, based on the original museum specimens supplemented by more recently collected specimens. The Belén flora provides a window to extinct forests in South America before the rising of the Andes in western Peru.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"University of Chicago Press","doi":"10.1086/665797","usgsCitation":"Manchester, S., Herrera, F., Fourtainer, E., Barron, J.A., and Martinez, J., 2012, Oligocene age of the classic Belén fruit and seed assemblage of north coastal Peru based on diatom biostratigraphy: Journal of Geology, v. 120, no. 4, p. 467-476, https://doi.org/10.1086/665797.","productDescription":"10 p.","startPage":"467","endPage":"476","numberOfPages":"10","ipdsId":"IP-038411","costCenters":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"links":[{"id":277395,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":277394,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1086/665797"}],"country":"Peru","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -81.33,-7.93 ], [ -81.33,-4.78 ], [ -76.91,-4.78 ], [ -76.91,-7.93 ], [ -81.33,-7.93 ] ] ] } } ] }","volume":"120","issue":"4","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"522af967e4b08fd0132e79bd","contributors":{"authors":[{"text":"Manchester, Steven R.","contributorId":24657,"corporation":false,"usgs":true,"family":"Manchester","given":"Steven R.","affiliations":[],"preferred":false,"id":483646,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Herrera, Fabiany","contributorId":73488,"corporation":false,"usgs":true,"family":"Herrera","given":"Fabiany","email":"","affiliations":[],"preferred":false,"id":483649,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Fourtainer, Elisabeth","contributorId":28153,"corporation":false,"usgs":true,"family":"Fourtainer","given":"Elisabeth","email":"","affiliations":[],"preferred":false,"id":483647,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Barron, John A. 0000-0002-9309-1145 jbarron@usgs.gov","orcid":"https://orcid.org/0000-0002-9309-1145","contributorId":2222,"corporation":false,"usgs":true,"family":"Barron","given":"John","email":"jbarron@usgs.gov","middleInitial":"A.","affiliations":[{"id":617,"text":"Volcano Science Center","active":true,"usgs":true}],"preferred":true,"id":483645,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Martinez, Jean-Noel","contributorId":51189,"corporation":false,"usgs":true,"family":"Martinez","given":"Jean-Noel","email":"","affiliations":[],"preferred":false,"id":483648,"contributorType":{"id":1,"text":"Authors"},"rank":5}]}}

A thick freshwater lens overlays brackish and saltwater in this coastal aquifer. Salinity profiles collected from uncased deep monitor wells (DMWs) commonly are used to monitor freshwater-lens thickness. However, vertical flow in DMWs can cause the measured salinity to differ from salinity in the adjacent aquifer or in an aquifer without a DWM. Substantial borehole flow and displacement of salinity in DMWs over several hundred feet have been observed in the Pearl Harbor aquifer. The objective of this study was to evaluate the effects of borehole flow on measured salinity profiles from DMWs. A numerical modeling approach incorporated aquifer hydraulic characteristics and recharge and withdrawal rates representative of the Pearl Harbor aquifer. Borehole flow caused by vertical hydraulic gradients associated with both the natural regional flow system and groundwater withdrawals was simulated.\n</p>\n<p>\nModel results indicate that, with all other factors being equal, greater withdrawal rates, closer withdrawal locations, or higher hydraulic conductivities of the well cause greater borehole flow and displacement of salinity in the well. Borehole flow caused by the natural groundwater-flow system is five orders of magnitude greater than vertical flow in a homogeneous aquifer, and borehole-flow directions are consistent with the regional flow system: downward flow in inland recharge areas and upward flow in coastal discharge areas. Displacement of salinity inside the DMWs associated with the regional groundwater-flow system ranges from less than 1 to 220 ft, depending on the location and assumed hydraulic conductivity of the well. For example, upward displacements of the 2 percent and 50 percent salinity depths in a well in the coastal discharge part of the flow system are 17 and 4.4 ft, respectively, and the average salinity difference between aquifer and borehole is 0.65 percent seawater salinity. Groundwater withdrawals and drawdowns generally occur at shallow depths in the freshwater system with respect to the depth of the DMW and cause upward flow in the DMW. Simulated groundwater withdrawal of 4.3 million gallons per day that is 100 ft from a DMW causes thirty times more borehole flow than borehole flow that is induced by the regional flow field alone. The displacement of the 2 percent borehole salinity depth increases from 17 to 33 ft, and the average salinity difference between aquifer and borehole is 0.85 percent seawater salinity. Peak borehole flow caused by local groundwater withdrawal near DMWs is directly proportional to the pumping rate in the nearby production well. Increasing groundwater withdrawal to 16.7 million gallons per day increases upward displacement of the 50 percent salinity depth (midpoint of the transition zone) from 4.6 to 77 ft, and the average salinity difference between aquifer and borehole is 1.4 percent seawater salinity.  Simulated groundwater withdrawal that is 3,000 ft away from DMWs causes less borehole flow and salinity displacements than nearby withdrawal. Simulated effects of groundwater withdrawal from a horizontal shaft and withdrawal from a vertical well in a homogeneous aquifer were similar. Generally, the 50 percent salinity depths are less affected by borehole flow than the 2 percent salinity depths. Hence, measured salinity profiles are useful for calibration of regional numerical models despite borehole-flow effects. Commonly, a 1 percent error in salinity is acceptable in numerical modeling studies. Incorporation of heterogeneity in the model is necessary to simulate long vertical steps observed in salinity profiles in southern O&#8216;ahu. A thick zone of low aquifer hydraulic conductivity limits exchange of water between aquifer and well and creates a long vertical step in the salinity profile. A heterogeneous basalt-aquifer scenario simulates observed vertical salinity steps and borehole flow that is consistent with measured borehole flow from DMWs in southern O&#8216;ahu. However, inclusion of local-scale heterogeneities in regional models generally is not warranted.","language":"English","publisher":"U.S. Geological Survey","publisherLocation":"Reston, VA","doi":"10.3133/sir20125009","usgsCitation":"Rotzoll, K., 2012, Numerical simulation of flow in deep open boreholes in a coastal freshwater lens, Pearl Harbor Aquifer, O&#8216;ahu, Hawai&#8216;i: U.S. Geological Survey Scientific Investigations Report 2012-5009, vi, 39 p., https://doi.org/10.3133/sir20125009.","productDescription":"vi, 39 p.","startPage":"i","endPage":"39","numberOfPages":"45","onlineOnly":"Y","additionalOnlineFiles":"N","costCenters":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"links":[{"id":204720,"rank":100,"type":{"id":15,"text":"Index Page"},"url":"https://pubs.usgs.gov/sir/2012/5009/","linkFileType":{"id":5,"text":"html"}},{"id":204736,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/sir_2012_5009.gif"}],"country":"United States","state":"Hawai'i","city":"Oahu","otherGeospatial":"Pearl Harbor Aquifer","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"505a691de4b0c8380cd73b80","contributors":{"authors":[{"text":"Rotzoll, Kolja 0000-0002-5910-888X kolja@usgs.gov","orcid":"https://orcid.org/0000-0002-5910-888X","contributorId":3325,"corporation":false,"usgs":true,"family":"Rotzoll","given":"Kolja","email":"kolja@usgs.gov","affiliations":[{"id":525,"text":"Pacific Islands Water Science Center","active":true,"usgs":true}],"preferred":false,"id":356637,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

The timing of smolt development varies among species, occurring soon after hatching in pink and chum salmon and after one to several years in Atlantic salmon. In many species the transformation is size dependent and occurs in spring, mediated through photoperiod and temperature cues. Smolt development is stimulated by several hormones including growth hormone, insulin-like growth factor-1, cortisol, and thyroid hormones, whereas prolactin is generally inhibitory. Increased salinity tolerance is one of the most important and tractable changes, and is caused by alteration in the function of the major osmoregulatory organs, the gill, gut, and kidney. Increased abundance of specific ion transporters (Na+/K+-ATPase, Na+/K+/Cl− cotransporter and apical Cl− channel) in gill ionocytes results in increased salt secretory capacity, increased growth and swimming performance in seawater, and higher marine survival.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Euryhaline fishes","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Elsevier","doi":"10.1016/B978-0-12-396951-4.00005-0","usgsCitation":"McCormick, S., 2012, Smolt physiology and endocrinology, chap. 5 <i>of</i> Euryhaline fishes, v. 32, p. 199-251, https://doi.org/10.1016/B978-0-12-396951-4.00005-0.","productDescription":"53 p.","startPage":"199","endPage":"251","numberOfPages":"53","ipdsId":"IP-042555","costCenters":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"links":[{"id":276688,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"32","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"520f49e7e4b0fc50304bc509","contributors":{"editors":[{"text":"McCormick, Stephen D. 0000-0003-0621-6200 smccormick@usgs.gov","orcid":"https://orcid.org/0000-0003-0621-6200","contributorId":39666,"corporation":false,"usgs":true,"family":"McCormick","given":"Stephen D.","email":"smccormick@usgs.gov","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":false,"id":509219,"contributorType":{"id":2,"text":"Editors"},"rank":1},{"text":"Farrell, Anthony Peter","contributorId":112579,"corporation":false,"usgs":true,"family":"Farrell","given":"Anthony","email":"","middleInitial":"Peter","affiliations":[],"preferred":false,"id":509220,"contributorType":{"id":2,"text":"Editors"},"rank":2},{"text":"Brauner, Colin J.","contributorId":113839,"corporation":false,"usgs":true,"family":"Brauner","given":"Colin","email":"","middleInitial":"J.","affiliations":[],"preferred":false,"id":509221,"contributorType":{"id":2,"text":"Editors"},"rank":3}],"authors":[{"text":"McCormick, Stephen D. 0000-0003-0621-6200 smccormick@usgs.gov","orcid":"https://orcid.org/0000-0003-0621-6200","contributorId":39666,"corporation":false,"usgs":true,"family":"McCormick","given":"Stephen D.","email":"smccormick@usgs.gov","affiliations":[{"id":365,"text":"Leetown Science Center","active":true,"usgs":true}],"preferred":false,"id":473898,"contributorType":{"id":1,"text":"Authors"},"rank":1}]}}

We developed and tested a conceptual model for nitrate removal in deep sediments in a nitrogen-rich river network. The model predicts that oxic, nitrate-rich groundwater will become depleted in nitrate as groundwater upwelling through sediments encounters a zone that contains buried particulate organic carbon, which promotes redox conditions favorable for nitrate removal. We tested the model at eight sites in upwelling reaches of lotic ecosystems in the Waupaca River Watershed that varied by three orders of magnitude in groundwater nitrate concentration. We measured denitrification potential in sediment core sections to 30 cm and developed vertical nitrate profiles to a depth of about 1 m with peepers and piezometer nests. Denitrification potential was higher, on average, in shallower core sections. However, core sections deeper than 5 cm accounted for 70%, on average, of the depth-integrated denitrification potential. Denitrification potential increased linearly with groundwater nitrate concentration up to 2 mg NO<sub>3</sub>-N/L but the relationship broke down at higher concentrations (> 5 mg NO<sub>3</sub>-N/L), a pattern that suggests nitrate saturation. At most sites groundwater nitrate declined from high concentrations at depth to much lower concentrations prior to discharge into the surface water. The profiles suggested that nitrate removal occurred at sediment depths between 20 and 40 cm. Dissolved oxygen concentrations were much higher in deep sediments than in pore water at 5 cm sediment depth at most locations. The substantial denitrification potential in deep sediments coupled with the declines in nitrate and dissolved oxygen concentrations in upwelling groundwater suggest that our conceptual model for nitrate removal in deep sediments is applicable to this river network. Our results suggest that nitrate removal rates can be high in deep sediments of upwelling stream reaches, which may have implications for efforts to understand and quantify nitrogen transport and removal at larger scales.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research: Biogeosciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Geophysical Union","doi":"10.1029/2012JG001990","usgsCitation":"Stelzer, R.S., and Bartsch, L., 2012, Nitrate removal in deep sediments of a nitrogen-rich river network: A test of a conceptual model: Journal of Geophysical Research: Biogeosciences, v. 117, no.
