Until recently, the interrelations among the SWRC, HCF, and SSCC have not been well established. This work sought experimental confirmation of interrelations among these three constitutive functions. Results taken from the literature for six soils and those obtained for 11 different soils were used. Using newly established analytical relations among the SWRC, HCF, and SSCC and these test results, the authors showed that these three constitutive relations can be defined by a common set of hydromechanical parameters. The coefficient of determination for air-entry pressures determined independently using hydraulic and mechanical methods is >0.99, >0.98 for the pore size parameter, and 0.94 for the residual degree of saturation. One practical implication is that one of any of the four experiments (axis-translation, hydraulic, shear-strength, or deformation) is sufficient to quantify all three constitutive relations.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geotechnical and Geoenvironmental Engineering","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"American Society of Civil Engineers","doi":"10.1061/(ASCE)GT.1943-5606.0001085","usgsCitation":"Lu, N., Kaya, M., and Godt, J.W., 2014, Interrelations among the soil-water retention, hydraulic conductivity, and suction-stress characteristic curves: Journal of Geotechnical and Geoenvironmental Engineering, v. 140, no. 5, 10 p., https://doi.org/10.1061/(ASCE)GT.1943-5606.0001085.","productDescription":"10 p.","numberOfPages":"10","ipdsId":"IP-053813","costCenters":[{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"links":[{"id":289401,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":289395,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1061/(ASCE)GT.1943-5606.0001085"}],"volume":"140","issue":"5","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53b7b18fe4b0388651d917cd","contributors":{"authors":[{"text":"Lu, Ning","contributorId":191360,"corporation":false,"usgs":false,"family":"Lu","given":"Ning","email":"","affiliations":[{"id":12620,"text":"U.S. Army Corp. of Engineers","active":true,"usgs":false}],"preferred":false,"id":495612,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kaya, Murat","contributorId":103576,"corporation":false,"usgs":true,"family":"Kaya","given":"Murat","email":"","affiliations":[],"preferred":false,"id":495613,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Godt, Jonathan W. 0000-0002-8737-2493 jgodt@usgs.gov","orcid":"https://orcid.org/0000-0002-8737-2493","contributorId":1166,"corporation":false,"usgs":true,"family":"Godt","given":"Jonathan","email":"jgodt@usgs.gov","middleInitial":"W.","affiliations":[{"id":508,"text":"Office of the AD Hazards","active":true,"usgs":true},{"id":300,"text":"Geologic Hazards Science Center","active":true,"usgs":true}],"preferred":true,"id":495611,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Urbanized estuaries are critical wintering and stopover areas for many declining sea ducks in North America; however, conservation measures within estuaries are difficult to establish given lack of knowledge about habitat use by these species and the variety of competing human interests. We applied hierarchical modeling to evaluate resource selection of sea ducks (surf scoters, Melanitta perspicillata) wintering in San Francisco Bay, California, USA, a large and highly urbanized estuary. We also examined their distribution, home range, and movements with respect to key habitat features and regions within the estuary. Herring roe was the strongest predictor of bird locations; however, eelgrass, water depth and salinity were also highly-ranked, with sea ducks using deeper areas of higher salinity associated with herring roe and eelgrass presence during mid-winter. Sea ducks were also strongly associated with ferry routes, suggesting these areas may contain resources that are too important to avoid and emphasizing the need to better understand water traffic effects. Movements and home range size differed between males and females in early winter but became more similar in late winter. Birds traveled farther and used several sub-bays in early winter compared to mid-winter when herring roe availability peaked in the Central Bay. Our findings identified key environmental variables, highlighted core use areas, and documented critical periods for consideration when developing conservation plans for sea ducks in urbanized estuaries.","language":"English","publisher":"Elsevier","doi":"10.1016/j.biocon.2013.10.021","usgsCitation":"De La Cruz, S.E., Eadie, J.M., Miles, A.K., Yee, J., Spragens, K., Palm, E., and Takekawa, J.Y., 2014, Resource selection and space use by sea ducks during the non-breeding season: Implications for habitat conservation planning in urbanized estuaries: Biological Conservation, v. 169, p. 68-78, https://doi.org/10.1016/j.biocon.2013.10.021.","productDescription":"11 p.","startPage":"68","endPage":"78","numberOfPages":"11","ipdsId":"IP-028582","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":293842,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"California","otherGeospatial":"San Francisco Bay","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.5228,37.4452 ], [ -122.5228,38.1442 ], [ -122.0369,38.1442 ], [ -122.0369,37.4452 ], [ -122.5228,37.4452 ] ] ] } } ] }","volume":"169","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54140b26e4b082fed288b963","contributors":{"authors":[{"text":"De La Cruz, Susan E.

Pixel-by-pixel accuracy assessments showed that ACCA produced an overall accuracy of 96 percent (K<sub>hat</sub><span>&nbsp;</span>= 0.8) when tested using independent data layers. Furthermore, ACCA-generated county cropland areas showed high agreement (R-square values 0.94) when compared with three independent data sources: (a) US Department of Agriculture (USDA) cropland data layer derived cropland areas, (b) county specific crop acreage data from the Farm Service Agency, and (c) the Census of Agriculture data for the 58 counties in California. Our results demonstrate the ability of ACCA to generate cropland extent and areas over space and time, in an automated fashion with high degree of accuracies year after year, greatly contributing to

Characters are confirmed in specimens of the type species, Rhynchelmis (Sutroa) rostrata (Eisen, 1888), collected from the type locality. Rhynchelmis (Sutroa) klamathensis Fend n. sp. is described from open water benthic habitats in Upper Klamath Lake, Oregon, USA. It resembles other R. (Sutroa) species in the paired spermathecal diverticula, the spermathecal and penial bulbs, the histological structure of the atria, the nonfunctional anterior male funnels, and the arrangement of blood vessels. Rhynchelmis klamathensis differs from all Nearctic Rhynchelmis in lacking a filiform proboscis. The combination of large body size, the elongate spermathecal ducts with paired and usually unbranched diverticula, the highly contorted atria, and the complex male pores with conical penes also distinguish typical R. klamathensis from other Rhynchelmis species. Smaller specimens with otherwise similar morphology, from the Sacramento River Delta, California, are also assigned to this species. Rhynchelmis (Sutroa) diespluviae Fend n. sp. is described from several stream sites, mostly in northern Idaho, USA. Rhynchelmis diespluviae differs from closely related species in morphology of the conical penes, and in the structure and anterolateral position of the paired spermathecae.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Zootaxa","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Magnolia Press","doi":"10.11646/zootaxa.3760.2.3","usgsCitation":"Fend, S.V., and Carter, J.L., 2014, <i>Rhynchelmis</i> subgenus <i>Sutroa</i> Eisen new rank, with two new species from western North America (Annelida, Clitellata, Lumbriculidae): Zootaxa, v. 3760, no. 2, p. 180-210, https://doi.org/10.11646/zootaxa.3760.2.3.","productDescription":"31 p.","startPage":"180","endPage":"210","numberOfPages":"31","ipdsId":"IP-043296","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"links":[{"id":282032,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282031,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.11646/zootaxa.3760.2.3"}],"country":"United States","state":"Oregon","otherGeospatial":"Upper Klamath Lake","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -122.105786,42.233568 ], [ -122.105786,42.598638 ], [ -121.801603,42.598638 ], [ -121.801603,42.233568 ], [ -122.105786,42.233568 ] ] ] } } ] }","volume":"3760","issue":"2","noUsgsAuthors":false,"publicationDate":"2014-01-31","publicationStatus":"PW","scienceBaseUri":"539a2a22e4b0a59b26497037","contributors":{"authors":[{"text":"Fend, Steven V. 0000-0002-4638-6602 svfend@usgs.gov","orcid":"https://orcid.org/0000-0002-4638-6602","contributorId":3591,"corporation":false,"usgs":true,"family":"Fend","given":"Steven","email":"svfend@usgs.gov","middleInitial":"V.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":489926,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carter, James L. 0000-0002-0104-9776 jlcarter@usgs.gov","orcid":"https://orcid.org/0000-0002-0104-9776","contributorId":3278,"corporation":false,"usgs":true,"family":"Carter","given":"James","email":"jlcarter@usgs.gov","middleInitial":"L.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":489925,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

We investigated patterns of sediment accretion in riparian wetlands along the non-tidal through oligohaline portion of two coastal plain rivers in Maryland, U.S.A., and how flow velocity, water level, and suspended sediment concentration (SSC) in the channel may have contributed to those patterns. Sediment accretion was measured over a one year period using artificial marker horizons, channel hydrology was measured over a one month period using acoustic Doppler current profilers, and SSC was predicted from acoustic backscatter. Riparian sediment accretion was lowest at the non-tidal sites (mean and standard deviation = 8 ± 8 mm yr<sup>-1</sup>), highest at the upstream tidal freshwater forested wetlands (TFFW) (33 ± 28 mm yr<sup>-1</sup>), low at the midstream TFFW (12 ± 9 mm yr<sup>-1</sup>), and high at the oligohaline (fresh-to-brackish) marshes (19 ± 8 mm yr<sup>-1</sup>). Channel maximum flood and ebb velocity was 2-fold faster at the oligohaline than tidal freshwater zone on both tidal rivers, corresponding with the differences in in-channel SSC: the oligohaline zone's SSC was more than double the tidal freshwater zone's, and was greater than historical SSC at the non-tidal gages. The tidal wave characteristics differed between rivers, leading to significantly greater in-channel SSC during floodplain inundation in the weakly convergent than the strongly convergent tidal river. Overall sediment accretion was higher in the embayed river likely due to a single storm discharge and associated sedimentation.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Journal of Geophysical Research F: Earth Surface","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"John Wiley & Sons","publisherLocation":"Hoboken, NJ","doi":"10.1002/2013JF002737","usgsCitation":"Ensign, S., Noe, G., and Hupp, C.R., 2014, Linking channel hydrology with riparian wetland accretion in tidal rivers: Journal of Geophysical Research F: Earth Surface, v. 119, no. 1, p. 28-44, https://doi.org/10.1002/2013JF002737.","productDescription":"17 p.","startPage":"28","endPage":"44","numberOfPages":"17","ipdsId":"IP-049027","costCenters":[{"id":434,"text":"National Research Program","active":false,"usgs":true}],"links":[{"id":473247,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1002/2013jf002737","text":"Publisher Index Page"},{"id":280641,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":280640,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1002/2013JF002737"}],"country":"United States","state":"Maryl","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -77.5085,36.9279 ], [ -77.5085,39.6015 ], [ -74.8938,39.6015 ], [ -74.8938,36.9279 ], [ -77.5085,36.9279 ] ] ] } } ] }","volume":"119","issue":"1","noUsgsAuthors":false,"publicationDate":"2014-01-14","publicationStatus":"PW","scienceBaseUri":"53cd64b4e4b0b290850ff9b9","contributors":{"authors":[{"text":"Ensign, Scott H.","contributorId":81397,"corporation":false,"usgs":true,"family":"Ensign","given":"Scott H.","affiliations":[],"preferred":false,"id":481029,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Noe, Gregory B.","contributorId":77805,"corporation":false,"usgs":true,"family":"Noe","given":"Gregory B.","affiliations":[],"preferred":false,"id":481028,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Hupp, Cliff R. 0000-0003-1853-9197 crhupp@usgs.gov","orcid":"https://orcid.org/0000-0003-1853-9197","contributorId":2344,"corporation":false,"usgs":true,"family":"Hupp","given":"Cliff","email":"crhupp@usgs.gov","middleInitial":"R.","affiliations":[{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":481027,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

We focus on detecting and quantifying Li, Ba, Rb, and Sr in targets analyzed during the first 100 sols, from Bradbury Landing Site to Rocknest. Univariate peak area models and multivariate partial least squares models are presented. Li, detected for the first time directly on Mars, is generally low (<15 ppm). The lack of soil enrichment in Li, which is highly fluid mobile, is consistent with limited influx of subsurface waters contributing to the upper soils. Localized enrichments of up to ~60 ppm Li have been observed in several rocks but the host mineral for Li is unclear. Bathurst_Inlet is a fine-grained bedrock unit in which several analysis locations show a decrease in Li and other alkalis with depth, which may imply that the unit has undergone low-level aqueous alteration that has preferentially drawn the alkalis to the surface. Ba (~1000 ppm) was detected in a buried pebble in the Akaitcho sand ripple and it appears to correlate with Si, Al, Na, and K, indicating a possible feldspathic composition. Rb and Sr are in the conglomerate Link at abundances >100 ppm and >1000 ppm, respectively. These analysis locations tend to have high Si and alkali abundances, consistent with a feldspar composition. Together, these trace element observations provide possible evidence of magma differentiation and aqueous alteration.","language":"English","publisher":"American Geophysical

Since then, blooms have occurred primarily in a 39-km section of Rapid Creek while blooms were rarely observed in other Black Hills streams. In this study, we evaluated factors related to the presence and development of visible colonies of D. geminata in four streams of the Black Hills. At the watershed scale, stream gradient was negatively associated with the occurrence of D. geminata whereas stream width was positively related to D. geminata presence. At the stream scale, D. geminata coverage was inversely related to canopy coverage and iron concentration. At the local scale, shading by bridges virtually eliminated growth of D. geminata colonies under bridges. At all three scales, proxy measures of light such as stream width, canopy coverage, and bridge shading revealed that light availability was an important factor influencing the presence and coverage of D. geminata colonies.

Close examination shows some important differences in the conceptual models that define bioavailability for metals and Me-ENMs. Metals are delivered to aquatic animals from Me-ENMs via water, ingestion, and incidental surface exposure. Both metal released from the Me-ENM and uptake of the nanoparticle itself contribute to bioaccumulation. Some mechanisms of toxicity and some of the metrics describing exposure may differ from metals alone. Bioavailability is driven by complex interaction of particle attributes, environmental transformations, and biological traits. Characterization of Me-ENMs is an essential part of understanding bioavailability and requires novel methodologies. The relative importance of the array of processes that could affect Me-ENM bioavailability remains poorly known, but new approaches and models are developing rapidly. Enough is known, however, to conclude that traditional approaches to exposure assessment for metals would not be adequate to assess risks from Me-ENMs.","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Frontiers of nanoscience: Nanoscience and the environment","largerWorkSubtype":{"id":15,"text":"Monograph"},"language":"English","publisher":"Elsevier","doi":"10.1016/B978-0-08-099408-6.00005-0","usgsCitation":"Luoma, S.N., Khan, F., and Croteau, M., 2014, Bioavailability and bioaccumulation of metal-based engineered nanomaterials in aquatic environments: Concepts and processes, chap. 5 <i>of</i> Frontiers of nanoscience: Nanoscience and the environment, v. 7, p. 157-193, https://doi.org/10.1016/B978-0-08-099408-6.00005-0.","productDescription":"37 p.","startPage":"157","endPage":"193","numberOfPages":"37","ipdsId":"IP-053018","costCenters":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":294848,"rank":0,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"7","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"542e692ce4b092f17df5a71c","contributors":{"authors":[{"text":"Luoma, Samuel N. 0000-0001-5443-5091 snluoma@usgs.gov","orcid":"https://orcid.org/0000-0001-5443-5091","contributorId":2287,"corporation":false,"usgs":true,"family":"Luoma","given":"Samuel","email":"snluoma@usgs.gov","middleInitial":"N.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true}],"preferred":true,"id":498959,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Khan, Farhan R.","contributorId":102407,"corporation":false,"usgs":true,"family":"Khan","given":"Farhan R.","affiliations":[],"preferred":false,"id":498961,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Croteau, Marie-Noele","contributorId":51668,"corporation":false,"usgs":true,"family":"Croteau","given":"Marie-Noele","email":"","affiliations":[],"preferred":false,"id":498960,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

To this end, we examined size of age-0 crappies in four flood-control reservoirs in northwest Mississippi over 4years. Age-0 crappies inhabiting uplake floodplain habitats grew to a larger size than fish in downlake embayments, but this trend depended on species, length of time a reservoir was dewatered in the months preceding spawning, and reservoir water level in the months following spawning.

Mussels live most of their lives burrowed in sediment, so understanding the effect of sediment on thermal sensitivity is a necessary step in evaluating the effectiveness of the water-only standard method, on which the regulatory framework for potential thermal criteria currently is based, as a test of thermal sensitivity. We developed a method for testing thermal sensitivity of juvenile mussels in sediment and used the method to assess thermal tolerance of 4 species across a range of temperatures common during summer. Stream beds may provide a thermal refuge in the wild, but we hypothesized that the presence of sediment alone does not alter thermal sensitivity. We also evaluated the effects of 2 temperature acclimation levels (22 and 27&deg;C) and 2 water levels (watered and dewatered treatments). We then compared results from the sediment tests to those conducted using the water-only standard methods. We also conducted water-only LT tests with mussel larvae (glochidia) for comparison with the juvenile life stage. We found few consistent differences in thermal tolerance between sediment and water-only treatments, between acclimation temperatures, between waterlevel treatments, among species, or between juvenile and glochidial life stages (LT50 range = 33.3-37.2&deg;C; mean = 35.6&deg;C), supporting our hypothesis that the presence of sediment alone does not alter thermal sensitivity.

Fractionated and unfractionated FAs obtained from streamwater and suspended sediment were utilized in acute Cu toxicity tests on ,i&gt;Ceriodaphnia dubia. Toxicity test results with equal FA concentrations (6 mg FA/L) show that the fractionated dissolved FA was 3 times less effective at reducing Cu toxicity (EC<sup>50</sup> 13 &plusmn; 0.6 &mu;g Cu/L) than were the unfractionated dissolved FAs (EC<sup>50</sup> 39 &plusmn; 0.4 and 41 &plusmn; 1.2 &mu;g Cu/L). The fractionation is a consequence of preferential sorption of molecules having strong metal-binding (more aromatic) moieties to precipitating Fe- and Al-rich oxyhydroxides, causing the remaining dissolved FA to be depleted in these functional groups. As a result, there is more bioavailable dissolved Cu in the water and hence greater potential for Cu toxicity to aquatic organisms. In predicting Cu toxicity, biotic ligand models (BLMs) take into account dissolved organic carbon (DOC) concentration; however, unless DOC characteristics are accounted for, model predictions can underestimate acute Cu toxicity for water containing fractionated dissolved FA. This may have implications for water-quality criteria in systems containing Fe- and Al-rich sediment, and in mined and mineralized areas in particular.

We quantified factors within the riparian zone of the Kansas River, USA, and within its tributaries that influenced sandbar size and density using aerial photographs and land use/land cover (LULC) data. We developed,&nbsp;<i>a priori</i><span>, 16 linear regression models focused on LULC at the local, adjacent upstream river bend, and the segment (18&ndash;44&thinsp;km upstream) scales and used an information theoretic approach to determine what alterations best predicted the size and density of sandbars. Variation in sandbar density was best explained by the LULC within contributing tributaries at the segment scale, which indicated reduced sandbar density with increased forest cover within tributary watersheds. Similarly, LULC within contributing tributary watersheds at the segment scale best explained variation in sandbar size. These models indicated that sandbar size increased with agriculture and forest and decreased with urban cover within tributary watersheds. Our findings suggest that sediment supply and delivery from upstream tributary watersheds may be influential on sandbars within the Kansas River and that preserving natural grassland and reducing woody encroachment within tributary watersheds in Great Plains rivers may help improve sediment delivery to help restore natural river function.</span></p>","language":"English","publisher":"John Wiley & Sons","publisherLocation":"Chichester, West Sussex, UK","doi":"10.1002/rra.2811","usgsCitation":"Fischer, J., Paukert, C.P., and Daniels, M., 2014, Influence of riparian and watershed alterations on sandbars in a Great Plains river: River Research and Applications, v. 31, no. 9, p. 1140-1150, https://doi.org/10.1002/rra.2811.","productDescription":"11 p.","startPage":"1140","endPage":"1150","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-044525","costCenters":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"links":[{"id":305651,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"31","issue":"9","publishingServiceCenter":{"id":8,"text":"Raleigh PSC"},"noUsgsAuthors":false,"publicationDate":"2014-08-01","publicationStatus":"PW","scienceBaseUri":"55a0ecb2e4b0183d66e43043","contributors":{"authors":[{"text":"Fischer, Jeffrey M. 0000-0003-2996-9272 fischer@usgs.gov","orcid":"https://orcid.org/0000-0003-2996-9272","contributorId":573,"corporation":false,"usgs":true,"family":"Fischer","given":"Jeffrey M.","email":"fischer@usgs.gov","affiliations":[{"id":451,"text":"National Water Quality Assessment Program","active":true,"usgs":true}],"preferred":false,"id":564597,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Paukert, Craig P. 0000-0002-9369-8545 cpaukert@usgs.gov","orcid":"https://orcid.org/0000-0002-9369-8545","contributorId":879,"corporation":false,"usgs":true,"family":"Paukert","given":"Craig","email":"cpaukert@usgs.gov","middleInitial":"P.","affiliations":[{"id":198,"text":"Coop Res Unit Atlanta","active":true,"usgs":true}],"preferred":true,"id":564259,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Daniels, M.L.","contributorId":52689,"corporation":false,"usgs":true,"family":"Daniels","given":"M.L.","email":"","affiliations":[],"preferred":false,"id":564598,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

The use of pack stock has become a contentious and litigious issue for land management agencies in the region inter alia due to concerns over effects on the environment. The potential environmental effects of pack stock on Sierra Nevada meadow ecosystems are reviewed and it is concluded that the use of pack stock has the potential to influence the following: (1) water nutrient dynamics, sedimentation, temperature, and microbial pathogen content; (2) soil chemistry, nutrient cycling, soil compaction and hydrology; (3) plant individuals, populations and community dynamics, non-native invasive species, and encroachment of woody species; and (4) wildlife individuals, populations and communities. It is considered from currently available information that management objectives of pack stock should include the following: minimise bare ground, maximise plant cover, maintain species composition of native plants, minimise trampling, especially on wet soils and stream banks, and minimise direct urination and defecation by pack stock into water. However, incomplete documentation of patterns of pack stock use and limited past research limits current understanding of the effects of pack stock, especially their effects on water, soils and wildlife. To improve management of pack stock in this region, research is needed on linking measurable monitoring variables (e.g. plant cover) with environmental relevancy (e.g. soil erosion processes, wildlife habitat use), and identifying specific environmental thresholds of degradation along gradients of pack stock use in Sierra Nevada meadows.</p>","language":"English","publisher":"American Society of Range Management","publisherLocation":"Denver, CO","doi":"10.1071/RJ14050","usgsCitation":"Ostoja, S.M., Brooks, M.L., Moore, P.E., Berlow, E.L., Blank, R., Roche, J., Chase, J.T., and Haultain, S., 2014, Potential environmental effects of pack stock on meadow ecosystems of the Sierra Nevada, USA: Rangeland Journal, v. 36, no. 5, p. 411-427, https://doi.org/10.1071/RJ14050.","productDescription":"17 p.","startPage":"411","endPage":"427","numberOfPages":"17","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-032478","costCenters":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"links":[{"id":298100,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"36","issue":"5","publishingServiceCenter":{"id":1,"text":"Sacramento PSC"},"noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"54ec5d45e4b02d776a67dab0","contributors":{"authors":[{"text":"Ostoja, Steven M. sostoja@usgs.gov","contributorId":3039,"corporation":false,"usgs":true,"family":"Ostoja","given":"Steven","email":"sostoja@usgs.gov","middleInitial":"M.","affiliations":[{"id":33665,"text":"USDA California Climate Hub, UC Davis","active":true,"usgs":false},{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":false,"id":540954,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Brooks, Matthew L. 0000-0002-3518-6787 mlbrooks@usgs.gov","orcid":"https://orcid.org/0000-0002-3518-6787","contributorId":393,"corporation":false,"usgs":true,"family":"Brooks","given":"Matthew","email":"mlbrooks@usgs.gov","middleInitial":"L.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":540952,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Moore, Peggy E. 0000-0002-8481-2617 peggy_moore@usgs.gov","orcid":"https://orcid.org/0000-0002-8481-2617","contributorId":3365,"corporation":false,"usgs":true,"family":"Moore","given":"Peggy","email":"peggy_moore@usgs.gov","middleInitial":"E.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":540953,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Berlow, Eric L.","contributorId":91416,"corporation":false,"usgs":false,"family":"Berlow","given":"Eric","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":540950,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Blank, Robert","contributorId":139377,"corporation":false,"usgs":false,"family":"Blank","given":"Robert","email":"","affiliations":[{"id":12755,"text":"USDA Ag Research Service, Reno, NV","active":true,"usgs":false}],"preferred":false,"id":540955,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Roche, Jim","contributorId":35073,"corporation":false,"usgs":true,"family":"Roche","given":"Jim","email":"","affiliations":[],"preferred":false,"id":540958,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Chase, Jennifer T. jchase@usgs.gov","contributorId":3961,"corporation":false,"usgs":true,"family":"Chase","given":"Jennifer","email":"jchase@usgs.gov","middleInitial":"T.","affiliations":[{"id":651,"text":"Western Ecological Research Center","active":true,"usgs":true}],"preferred":true,"id":540951,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Haultain, Sylvia","contributorId":139378,"corporation":false,"usgs":false,"family":"Haultain","given":"Sylvia","email":"","affiliations":[{"id":12756,"text":"Plant Ecologist, NPS, Sequoia Kings Cyn NPs","active":true,"usgs":false}],"preferred":false,"id":540956,"contributorType":{"id":1,"text":"Authors"},"rank":8}]}}

The organisation embraces a grassroots approach to engage researchers from varying disciplines, sites spanning geographic and ecological gradients, and novel sensor and cyberinfrastructure to synthesise high-frequency lake data at scales ranging from local to global. The high-frequency data provide a platform to rigorously validate process- based ecological models because model simulation time steps are better aligned with sensor measurements than with lower-frequency, manual samples. Two case studies from Trout Bog, Wisconsin, USA, and Lake Rotoehu, North Island, New Zealand, are presented to demonstrate that in the past, ecological model outputs (e.g., temperature, chlorophyll) have been relatively poorly validated based on a limited number of directly comparable measurements, both in time and space. The case studies demonstrate some of the difficulties of mapping sensor measurements directly to model state variable outputs as well as the opportunities to use deviations between sensor measurements and model simulations to better inform process understanding. Well-validated ecological models provide a mechanism to extrapolate high-frequency sensor data in space and time, thereby potentially creating a fully 3-dimensional simulation of key variables of interest.</p>","language":"English","publisher":"International Association of Theoretical and Applied Limnology","publisherLocation":"Stuttgart","doi":"10.5268/IW-5.1.566","usgsCitation":"Hamilton, D.P., Carey, C.C., Arvola, L., Arzberger, P., Brewer, C.A., Cole, J.J., Gaiser, E., Hanson, P.C., Ibelings, B.W., Jennings, E., Kratz, T.K., Lin, F., McBride, C.G., de Motta Marques, D., Muraoka, K., Nishri, A., Qin, B., Read, J.S., Rose, K., Ryder, E., Weathers, K.C., Zhu, G., Trolle, D., and Brookes, J.D., 2014, A Global Lake Ecological Observatory Network (GLEON) for synthesising high-frequency sensor data for validation of deterministic ecological models: Inland Waters, v. 5, no. 1, p. 49-56, https://doi.org/10.5268/IW-5.1.566.","productDescription":"8 p.","startPage":"49","endPage":"56","numberOfPages":"8","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-061713","costCenters":[{"id":160,"text":"Center for Integrated Data Analytics","active":false,"usgs":true}],"links":[{"id":473256,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.5268/iw-5.1.566","text":"Publisher Index Page"},{"id":296705,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":296690,"type":{"id":15,"text":"Index Page"},"url":"https://www.fba.org.uk/journals/index.php/IW/article/view/566/441"}],"volume":"5","issue":"1","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"549165bae4b0d0759afaad7a","contributors":{"authors":[{"text":"Hamilton, David P. 0000-0002-9341-8777 hamiltond@usgs.gov","orcid":"https://orcid.org/0000-0002-9341-8777","contributorId":130968,"corporation":false,"usgs":false,"family":"Hamilton","given":"David","email":"hamiltond@usgs.gov","middleInitial":"P.","affiliations":[{"id":7184,"text":"Environmental Research Institute, University of Waikato, Hamilton, New Zealand","active":true,"usgs":false}],"preferred":true,"id":536729,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Carey, Cayelan C.","contributorId":130969,"corporation":false,"usgs":false,"family":"Carey","given":"Cayelan","email":"","middleInitial":"C.","affiliations":[{"id":7185,"text":"Department of Biological Sciences, Virginia Tech, Blacksburg, VA, USA","active":true,"usgs":false}],"preferred":false,"id":536730,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Arvola, Lauri","contributorId":130970,"corporation":false,"usgs":false,"family":"Arvola","given":"Lauri","affiliations":[{"id":7186,"text":"Lammi Biological Station, Lammi, Finland","active":true,"usgs":false}],"preferred":false,"id":536731,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Arzberger, Peter","contributorId":130971,"corporation":false,"usgs":false,"family":"Arzberger","given":"Peter","email":"","affiliations":[{"id":7187,"text":"University of California-San Diego, California Institute for Telecommunications and Information Technology, La Jolla, CA, USA","active":true,"usgs":false}],"preferred":false,"id":536732,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Brewer, Carol A.","contributorId":79777,"corporation":false,"usgs":true,"family":"Brewer","given":"Carol","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":536733,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Cole, Jon J","contributorId":130972,"corporation":false,"usgs":false,"family":"Cole","given":"Jon","email":"","middleInitial":"J","affiliations":[{"id":7188,"text":"Cary Institute of Ecosystem Studies, Millbrook, NY, USA","active":true,"usgs":false}],"preferred":false,"id":536734,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Gaiser, Evelyn","contributorId":61727,"corporation":false,"usgs":true,"family":"Gaiser","given":"Evelyn","affiliations":[],"preferred":false,"id":536735,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Hanson, Paul C.","contributorId":35634,"corporation":false,"usgs":false,"family":"Hanson","given":"Paul","email":"","middleInitial":"C.","affiliations":[{"id":12951,"text":"Center for Limnology, University of Wisconsin Madison","active":true,"usgs":false}],"preferred":false,"id":536736,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Ibelings, Bas W","contributorId":130973,"corporation":false,"usgs":false,"family":"Ibelings","given":"Bas","email":"","middleInitial":"W","affiliations":[{"id":7189,"text":"Institut F.A.

The essence of the call for integration is that harvest and habitat management affect the same resources, yet exist as separate endeavours with very different regulatory contexts. A common modelling framework could help these management streams to better understand their mutual effects. Particularly, how does successful habitat management increase harvest potential? Also, how do regional habitat programmes and large-scale harvest strategies affect continental population sizes (a metric used to express habitat goals)? In the ensuing five years, several projects took on different aspects of these challenges. While all of these projects are still on-going, and are not yet sufficiently developed to produce guidance for management decisions, they have been influential in expanding the dialogue and producing some important emerging lessons. The first lesson has been that one of the more difficult aspects of integration is not the integration across decision contexts, but the integration across spatial and temporal scales. Habitat management occurs at local and regional scales. Harvest management decisions are made at a continental scale. How do these actions, taken at different scales, combine to influence waterfowl population dynamics at all scales? The second lesson has been that consideration of the interface of habitat and harvest management can generate important insights into the objectives underlying the decision context. Often the objectives are very complex and trade-off against one another. The third lesson follows from the second &ndash; if an understanding of the fundamental objectives is paramount, there is no escaping the need for a better understanding of human dimensions, specifically the desires of hunters and nonhunters and the role they play in conservation. In the end, the compelling question is how to better understand, guide and justify decisions about conservation investments in waterfowl management. Future efforts to integrate harvest and habitat management will include completion of the species-specific case-studies, initiation of policy discussions around how to integrate the decision contexts and governing institutions, and possible consideration of a new level of integration &ndash; integration of harvest and habitats management decisions across waterfowl stocks.</p>","language":"English","publisher":"Wildfowl Trust","publisherLocation":"Gloucester, England","usgsCitation":"Osnas, E.E., Runge, M.C., Mattsson, B., Austin, J.E., Boomer, G.S., Clark, R.G., Devers, P., Eadie, J., Lonsdorf, E., and Tavernia, B., 2014, Managing harvest and habitat as integrated components: Wildfowl, v.

Little information exists about annual or seasonal survival rates of adult Red-throated Loons. This study used tracking data from satellite transmitters implanted into 33 Red-throated Loons captured on breeding areas in Alaska to estimate annual survival with the sampling effort split between two study periods: 2000–2002 and 2008–2010. Mortality was inferred from transmitted sensor data that indicated body temperature of the Red-throated Loon and voltage of the transmitter's battery. Two definitive mortalities occurred, resulting in an annual survival estimate of 0.920 (SE = 0.054). The fates of two additional Red-throated Loons were ambiguous and, when treated as mortalities, the annual survival estimate was 0.838 (SE = 0.074). All four putative mortalities occurred during the non-breeding season in the early study period. Oceanic conditions, indexed by the Pacific Decadal Oscillation, appeared to differ between the study periods with higher Pacific Decadal Oscillation values associated with the early study period. Given that high values for Pacific Decadal Oscillation were also associated with the large decline of Red-throated Loons observed in Alaska during 1977–1993, this study suggests that survival of adult Red-throated Loons may vary in relation to the state of the marine ecosystem and thus contribute to long-term variation in population trends.</span></p>","language":"English","publisher":"The Waterbird Society","doi":"10.1675/063.037.sp114","usgsCitation":"Schmutz, J.A., 2014, Survival of adult Red-throated Loons (Gavia stellata) may be linked to marine conditions: Waterbirds, v. 37, no.

Approximately 16% of the oil was chemically dispersed, at the surface and at 1500 m depth, using Corexit 9527 and Corexit 9500, which contain dioctyl sodium sulfosuccinate (DOSS) as a major surfactant component. This was the largest documented release of oil in history at substantial depth, and the first time large quantities of dispersant (0.77 million gallons of approximately 1.9 million gallons total) were applied to a subsurface oil plume. During two cruises in late May and early June, water samples were collected at the surface and at depth for DOSS analysis. Real-time fluorimetry data was used to infer the presence of oil components to select appropriate sampling depths. Samples were stored frozen and in the dark for approximately 6 months prior to analysis by liquid chromatography/tandem mass spectrometry with isotope-dilution quantification. The blank-limited method detection limit (0.25 μg L<sup>−1</sup>) was substantially less than the U.S. Environmental Protection Agency’s (USEPA) aquatic life benchmark of 40 μg L<sup>−1</sup>. Concentrations of DOSS exceeding 200 μg L<sup>−1</sup> were observed in one surface sample near the well site; in subsurface samples DOSS did not exceed 40 μg L<sup>−1</sup>. Although DOSS was present at high concentration in the immediate vicinity of the well where it was being continuously applied, a combination of biodegradation, photolysis, and dilution likely reduced persistence at concentrations exceeding the USEPA aquatic life benchmark beyond this immediate area.","language":"English","publisher":"Elsevier","doi":"10.1016/j.chemosphere.2013.08.049","usgsCitation":"Gray, J.L., Kanagy, L.K., Furlong, E.T., Kanagy, C., McCoy, J.W., Mason, A., and Lauenstein, G., 2014, Presence of the Corexit component dioctyl sodium sulfosuccinate in Gulf of Mexico waters after the 2010 Deepwater Horizon oil spill: Chemosphere, v. 95, p. 124-130, https://doi.org/10.1016/j.chemosphere.2013.08.049.","productDescription":"7 p.","startPage":"124","endPage":"130","numberOfPages":"7","ipdsId":"IP-037292","costCenters":[{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true},{"id":589,"text":"Toxic Substances Hydrology Program","active":true,"usgs":true}],"links":[{"id":288890,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":288889,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.chemosphere.2013.08.049"}],"country":"United States","otherGeospatial":"Gulf Of Mexico","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -91.5,28.0 ], [ -91.5,31.0 ], [ -87.0,31.0 ], [ -87.0,28.0 ], [ -91.5,28.0 ] ] ] } } ] }","volume":"95","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53ae77f1e4b0abf75cf2c5c2","contributors":{"authors":[{"text":"Gray, James L. 0000-0002-0807-5635 jlgray@usgs.gov","orcid":"https://orcid.org/0000-0002-0807-5635","contributorId":1253,"corporation":false,"usgs":true,"family":"Gray","given":"James","email":"jlgray@usgs.gov","middleInitial":"L.","affiliations":[{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true},{"id":452,"text":"National Water Quality Laboratory","active":true,"usgs":true},{"id":436,"text":"National Research Program - Eastern Branch","active":true,"usgs":true}],"preferred":true,"id":494989,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Kanagy, Leslie K. 0000-0001-5073-8538 lkkanagy@usgs.gov","orcid":"https://orcid.org/0000-0001-5073-8538","contributorId":4543,"corporation":false,"usgs":true,"family":"Kanagy","given":"Leslie","email":"lkkanagy@usgs.gov","middleInitial":"K.","affiliations":[{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true}],"preferred":true,"id":494990,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Furlong, Edward T. 0000-0002-7305-4603 efurlong@usgs.gov","orcid":"https://orcid.org/0000-0002-7305-4603","contributorId":740,"corporation":false,"usgs":true,"family":"Furlong","given":"Edward","email":"efurlong@usgs.gov","middleInitial":"T.","affiliations":[{"id":503,"text":"Office of Water Quality","active":true,"usgs":true},{"id":5046,"text":"Branch of Analytical Serv (NWQL)","active":true,"usgs":true},{"id":191,"text":"Colorado Water Science Center","active":true,"usgs":true},{"id":27111,"text":"National Water Quality Program","active":true,"usgs":true}],"preferred":true,"id":494988,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Kanagy, Chris J.","contributorId":81616,"corporation":false,"usgs":true,"family":"Kanagy","given":"Chris J.","affiliations":[],"preferred":false,"id":494993,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"McCoy, Jeff W. 0000-0002-9817-6711 jefmccoy@usgs.gov","orcid":"https://orcid.org/0000-0002-9817-6711","contributorId":738,"corporation":false,"usgs":true,"family":"McCoy","given":"Jeff","email":"jefmccoy@usgs.gov","middleInitial":"W.","affiliations":[{"id":37464,"text":"WMA - Laboratory & Analytical Services Division","active":true,"usgs":true}],"preferred":true,"id":494987,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Mason, Andrew","contributorId":10334,"corporation":false,"usgs":true,"family":"Mason","given":"Andrew","email":"","affiliations":[],"preferred":false,"id":494991,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Lauenstein, Gunnar","contributorId":50080,"corporation":false,"usgs":true,"family":"Lauenstein","given":"Gunnar","affiliations":[],"preferred":false,"id":494992,"contributorType":{"id":1,"text":"Authors"},"rank":7}]}}

Because methane is only sparingly soluble in seawater, measuring it without contamination is challenging for samples collected and processed in the presence of air. Several methods for analyzing dissolved methane are described in the literature, yet none has conducted a thorough assessment of the method yield, contamination issues during collection, transport and storage, and the effect of temperature changes and preservative. Previous extraction methods transfer methane from water to gas by either a \"sparge and trap\" or a \"headspace equilibration\" technique. The gas is then analyzed for methane by gas chromatography. Here, we revisit the headspace equilibration technique and describe a simple, inexpensive, and reliable method to measure methane in fresh and seawater, regardless of concentration. Within the range of concentrations typically found in surface seawaters (2-1000 nmol L<sup>-1</sup>), the yield of the method nears 100% of what is expected from solubility calculation following the addition of known amount of methane. In addition to being sensitive (detection limit of 0.1 ppmv, or 0.74 nmol L<sup>-1</sup>), this method requires less than 10 min per sample, and does not use highly toxic chemicals. It can be conducted with minimum materials and does not require the use of a gas chromatograph at the collection site. It can therefore be used in various remote working environments and conditions.</p>","language":"English","publisher":"American Society of Limnology and Oceanography","publisherLocation":"Waco, TX","doi":"10.4319/lom.2014.12.637","usgsCitation":"Magen, C., Lapham, L.L., Pohlman, J.W., Marshall, K.N., Bosman, S., Casso, M., and Chanton, J., 2014, A simple headspace equilibration method for measuring dissolved methane: Limnology and Oceanography: Methods, v. 12, p. 637-650, https://doi.org/10.4319/lom.2014.12.637.","productDescription":"14 p.","startPage":"637","endPage":"650","numberOfPages":"14","onlineOnly":"N","additionalOnlineFiles":"N","ipdsId":"IP-059425","costCenters":[{"id":678,"text":"Woods Hole Coastal and Marine Science Center","active":true,"usgs":true}],"links":[{"id":473263,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.4319/lom.2014.12.637","text":"Publisher Index Page"},{"id":299436,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"volume":"12","publishingServiceCenter":{"id":11,"text":"Pembroke PSC"},"noUsgsAuthors":false,"publicationDate":"2014-09-08","publicationStatus":"PW","scienceBaseUri":"5524ffa9e4b027f0aee3d46d","contributors":{"authors":[{"text":"Magen, C","contributorId":140084,"corporation":false,"usgs":false,"family":"Magen","given":"C","affiliations":[{"id":13382,"text":"Earth, Ocean and Atmospheric Science, Florida State University, Tallahassee, Florida 32306","active":true,"usgs":false}],"preferred":false,"id":544191,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Lapham, L.

Compositional data for fractures in the layered rocks suggest formation of Al-rich smectites by aqueous leaching.

Deposits at + 20 m are 481 ± 39 ka, possibly correlative to marine isotope stage (or MIS) 11, while those at + 12 and + 8 m are 120.5 ± 0.8 ka and 130.2 ± 0.8 ka, respectively, correlative to MIS 5.5. The age, elevations, and uplift rates derived from MIS 5.5 deposits on the Canary Islands allow calculations of hypothetical palaeo-sea levels during the MIS 11 high sea stand. Estimates indicate that the MIS 11 high sea stand likely was at least + 9 m (relative to present sea level) and could have been as high as + 24 m. The most conservative estimates of palaeo-sea level during MIS 11 would require an ice mass loss equivalent to all of the modern Greenland and West Antarctic ice sheets; the more extreme estimates would require additional ice mass loss from the East Antarctic ice sheet. Extralimital southern species of mollusks, found in both MIS 11 and MIS 5.5 deposits on the Canary Islands, imply warmer-than-modern sea surface temperatures during at least a part of MIS 11 and much warmer sea surface temperatures during at least a part of MIS 5.5. Both MIS 11 and MIS 5.5 marine deposits on the Canary Islands contain extralimital northern species of mollusks as well, indicating cooler-than-present waters at times during these interglacial periods. We hypothesize that the co-occurrence of extralimital southern and northern species of marine invertebrates in the fossil record of the Canary Islands reflects its geographic location with respect to major synoptic-scale controls on climate and ocean currents. Previous interglacials may have been characterized by early, insolation-forced warming, along with northward migration of the intertropical convergence zone (ITCZ), accompanied by weakened trade winds and diminished upwelling. This allowed the arrival of extralimital southern taxa from the tropical Senegalese faunal province. During later parts of the MIS 11 and 5.5 interglacials, decreased insolation may have resulted in southward migration of the ITCZ, strengthened trade winds, and re-establishment of upwelling. Such conditions may have brought about not only local extinction of the Senegalese fauna, but allowed southward migration of the cooler-water Mediterranean fauna to the Canary Islands in the later parts of interglacials, a complex palaeoclimate record that is mirrored in the deep-sea core record.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Palaeogeography, Palaeoclimatology, Palaeoecology","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Elsevier","doi":"10.1016/j.palaeo.2013.11.015","usgsCitation":"Muhs, D.R., Meco, J., and Simmons, K., 2014, Uranium-series ages of corals, sea level history, and palaeozoogeography, Canary Islands, Spain: an exploratory study for two Quaternary interglacial periods: Palaeogeography, Palaeoclimatology, Palaeoecology, v. 394, p. 99-118, https://doi.org/10.1016/j.palaeo.2013.11.015.","productDescription":"20 p.","startPage":"99","endPage":"118","numberOfPages":"20","ipdsId":"IP-048991","costCenters":[{"id":318,"text":"Geosciences and Environmental Change Science Center","active":true,"usgs":true}],"links":[{"id":488278,"rank":0,"type":{"id":41,"text":"Open Access External Repository Page"},"url":"http://hdl.handle.net/10553/17952","text":"External Repository"},{"id":294108,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":294107,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1016/j.palaeo.2013.11.015"}],"country":"Spain","otherGeospatial":"Canary Islands","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -18.1612,27.6378 ], [ -18.1612,29.4165 ], [ -13.3336,29.4165 ], [ -13.3336,27.6378 ], [ -18.1612,27.6378 ] ] ] } } ] }","volume":"394","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"541bf460e4b0e96537ddf8fd","contributors":{"authors":[{"text":"Muhs, Daniel R. 0000-0001-7449-251X dmuhs@usgs.gov","orcid":"https://orcid.org/0000-0001-7449-251X","contributorId":1857,"corporation":false,"usgs":true,"family":"Muhs","given":"Daniel","email":"dmuhs@usgs.gov","middleInitial":"R.","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":true,"id":501174,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Meco, Joaquin","contributorId":38485,"corporation":false,"usgs":true,"family":"Meco","given":"Joaquin","email":"","affiliations":[],"preferred":false,"id":501176,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Simmons, Kathleen R. ksimmons@usgs.gov","contributorId":4742,"corporation":false,"usgs":true,"family":"Simmons","given":"Kathleen R.","email":"ksimmons@usgs.gov","affiliations":[{"id":218,"text":"Denver Federal Center","active":false,"usgs":true}],"preferred":false,"id":501175,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}
