One of these functions is the production, transport, and transformation of organic matter that constitutes the “primary food supply,” that is, the food supply to the base of the food web. Interest in the primary food supply is motivated by evidence for sub-optimal food quantity or quality at trophic levels that support fish recruitment, including primary consumers such as clams, mysids, cladocerans, rotifers, and native copepods. We used the historical data set to examine the magnitudes of the most important organic matter sources for the Delta, the factors underlying their interannual and longer-term variability, and the implications of ecosystem rehabilitation actions for these sources. Here, we present a summary of the first phase of the analysis, including the quantitative importance of different organic matter sources and some of the hydrological controls on their year-to-year variability. The full report of this first phaseincluding data sources, the methods of calculation, and references, is in press elsewhere (Jassby and Cloern forthcoming). The historical data analysis is part of a larger project in which measurements of stable isotopes and biogeochemical markers, and experiments on organic matter biodegradation and zooplankton growth rates, are being used collectively to define the primary food resources and their quality. </p>","language":"English","publisher":"Interagency Ecological Program for the San Francisco Estuary","usgsCitation":"Jassby, A.D., and Cloern, J.E., 2000, Primary food resources in the Sacramento-San Joaquin Delta: Interagency Ecological Program Newsletter, v. 13, no. 3, p. 21-25.","productDescription":"5 p.","startPage":"21","endPage":"25","costCenters":[{"id":154,"text":"California Water Science Center","active":true,"usgs":true}],"links":[{"id":358449,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":358448,"rank":1,"type":{"id":11,"text":"Document"},"url":"https://water.ca.gov/-/media/DWR-Website/Web-Pages/Programs/Environmental-Services/Interagency-Ecological-Program/Files/Newsletters/IEP-Newsletter-2000-Vol13-Issue3.pdf","linkFileType":{"id":1,"text":"pdf"}}],"country":"United States","state":"California","otherGeospatial":"Sacramento-San Joaquin Delta","volume":"13","issue":"3","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"5c10fbdde4b034bf6a8091b2","contributors":{"authors":[{"text":"Jassby, Alan D.","contributorId":66403,"corporation":false,"usgs":true,"family":"Jassby","given":"Alan","email":"","middleInitial":"D.","affiliations":[],"preferred":false,"id":748742,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cloern, James E. 0000-0002-5880-6862 jecloern@usgs.gov","orcid":"https://orcid.org/0000-0002-5880-6862","contributorId":1488,"corporation":false,"usgs":true,"family":"Cloern","given":"James","email":"jecloern@usgs.gov","middleInitial":"E.","affiliations":[{"id":438,"text":"National Research Program - Western Branch","active":true,"usgs":true},{"id":37277,"text":"WMA - Earth System Processes Division","active":true,"usgs":true}],"preferred":true,"id":748743,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

These estuaries range from large fjords to shallow lagoons; from large to low freshwater flows. Natural hazards include E1 Niños, strong Pacific storms, and active tectonic activity. West Coast estuaries support a wide range of living resources: five salmon species, harvestable shellfish, waterfowl and marine birds, marine mammals, and a variety of algae and plants. Although populations of many of these living resources have declined (salmonids), others have increased (marine mammals). West Coast estuaries are also centers of commerce and increasingly large shipping traffic. The West Coast human population is rising faster than most other areas of the U.S. and Canada, and is distributed heavily in southern California, the San Francisco Bay area, around Puget Sound, and the Fraser River estuary. While water pollution is a problem in many of the urbanized estuaries, most estuaries do not suffer from poor water quality. Primary estuarine problems include habitat alterations, degradation, and loss; diverted freshwater flows; marine sediment contamination; and exotic species introductions. The growing West Coast economy and population are in part related to the quality of life, which is dependent on the use and enjoyment of abundant coastal natural resources.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Estuaries","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Springer","doi":"10.2307/1352998","usgsCitation":"Emmett, R., Llanso, R., Newton, J., Thom, R., Hornberger, M., Morgan, C., Levings, C., Copping, A., and Fishman, P., 2000, Geographic signatures of North American West Coast estuaries: Estuaries, v. 23, no. 6, p. 765-792, https://doi.org/10.2307/1352998.","productDescription":"28 p.","startPage":"765","endPage":"792","numberOfPages":"28","costCenters":[],"links":[{"id":281219,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281217,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.2307/1352998"}],"country":"Canada;United States","state":"British Columbia;California;Oregon;Washington","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -140.0,30.0 ], [ -140.0,55.0 ], [ -115.0,55.0 ], [ -115.0,30.0 ], [ -140.0,30.0 ] ] ] } } ] }","volume":"23","issue":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd5b23e4b0b290850f9d08","contributors":{"authors":[{"text":"Emmett, Robert","contributorId":9963,"corporation":false,"usgs":true,"family":"Emmett","given":"Robert","email":"","affiliations":[],"preferred":false,"id":488696,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Llanso, Roberto","contributorId":89803,"corporation":false,"usgs":true,"family":"Llanso","given":"Roberto","email":"","affiliations":[],"preferred":false,"id":488703,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Newton, Jan","contributorId":19082,"corporation":false,"usgs":true,"family":"Newton","given":"Jan","affiliations":[],"preferred":false,"id":488697,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Thom, Ron","contributorId":56555,"corporation":false,"usgs":true,"family":"Thom","given":"Ron","email":"","affiliations":[],"preferred":false,"id":488699,"contributorType":{"id":1,"text":"Authors"},"rank":4},{"text":"Hornberger, Michelle 0000-0002-7787-3446","orcid":"https://orcid.org/0000-0002-7787-3446","contributorId":49383,"corporation":false,"usgs":true,"family":"Hornberger","given":"Michelle","affiliations":[],"preferred":false,"id":488698,"contributorType":{"id":1,"text":"Authors"},"rank":5},{"text":"Morgan, Cheryl","contributorId":69062,"corporation":false,"usgs":true,"family":"Morgan","given":"Cheryl","email":"","affiliations":[],"preferred":false,"id":488700,"contributorType":{"id":1,"text":"Authors"},"rank":6},{"text":"Levings, Colin","contributorId":69409,"corporation":false,"usgs":true,"family":"Levings","given":"Colin","email":"","affiliations":[],"preferred":false,"id":488701,"contributorType":{"id":1,"text":"Authors"},"rank":7},{"text":"Copping, Andrea","contributorId":81806,"corporation":false,"usgs":true,"family":"Copping","given":"Andrea","email":"","affiliations":[],"preferred":false,"id":488702,"contributorType":{"id":1,"text":"Authors"},"rank":8},{"text":"Fishman, Paul","contributorId":100744,"corporation":false,"usgs":true,"family":"Fishman","given":"Paul","email":"","affiliations":[],"preferred":false,"id":488704,"contributorType":{"id":1,"text":"Authors"},"rank":9}]}}

Although the Mg/Ca data show considerable variability (“scatter”) that is common to single-shell chemical analyses, comparisons between cores, between core top shells and modern bottom water temperatures (BWT), and comparison to other paleo-BWT proxies, among other factors, suggest that multiple-shell average Mg/Ca ratios provide reliable estimates of BWT history at these sites. The BWT records show not only glacial-to-interglacial variations but also indicate BWT changes during the deglacial and within the Holocene interglacial stage. At the deeper sites (4500- and 3400-m water depth), BWT decreased during the last glacial maximum (LGM), the late Holocene, and possibly during the Younger Dryas. Maximum deep-sea warming occurred during the latest deglacial and early Holocene, when BWT exceeded modern values by as much as 2.5°C. This warming was apparently most intense around 3000 m, the depth of the modern-day core of North Atlantic deep water (NADW). The BWT variations at the deeper water sites are consistent with changes in thermohaline circulation: warmer BWT signifies enhanced NADW influence relative to Antarctic bottom water (AABW). Thus maximum NADW production and associated heat flux likely occurred during the early Holocene and decreased abruptly around 6500 years B.P., a finding that is largely consistent with paleonutrient studies in the deep North Atlantic. BWT changes in intermediate waters (1000-m water depth) of the subtropical gyre roughly parallel the deep BWT variations including dramatic mid-Holocene cooling of around 4°C. Joint consideration of the Mg/Ca-based BWT estimates and benthic oxygen isotopes suggests that the cooling was accompanied by a decrease in salinity at this site. Subsequently, intermediate waters warmed to modern values that match those of the early Holocene maximum of ∼7°C. Intermediate water BWT changes must also be driven by changes in ocean circulation. These results thus provide independent evidence that supports the hypothesis that deep-ocean circulation is closely linked to climate change over a range of timescales regardless of the mean climate state. More generally, the results further demonstrate the potential of benthic Mg/Ca ratios as a tool for reconstructing past ocean and climate conditions.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Geochemistry, Geophysics, Geosystems","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Wiley","doi":"10.1029/2000GC000046","usgsCitation":"Dwyer, G., Cronin, T.M., Baker, P.A., and Rodriguez-Lazaro, J., 2000, Changes in North Atlantic deep-sea temperature during climatic fluctuations of the last 25,000 years based on ostracode Mg/Ca ratios: Geochemistry, Geophysics, Geosystems, v. 1, no. 12, 17 p., https://doi.org/10.1029/2000GC000046.","productDescription":"17 p.","numberOfPages":"17","costCenters":[],"links":[{"id":479148,"rank":0,"type":{"id":40,"text":"Open Access Publisher Index Page"},"url":"https://doi.org/10.1029/2000gc000046","text":"Publisher Index Page"},{"id":281215,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281214,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1029/2000GC000046"}],"volume":"1","issue":"12","noUsgsAuthors":false,"publicationDate":"2000-12-28","publicationStatus":"PW","scienceBaseUri":"53cd506be4b0b290850f3531","contributors":{"authors":[{"text":"Dwyer, Gary S.","contributorId":67642,"corporation":false,"usgs":true,"family":"Dwyer","given":"Gary S.","affiliations":[],"preferred":false,"id":488693,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Cronin, Thomas M. 0000-0002-2643-0979 tcronin@usgs.gov","orcid":"https://orcid.org/0000-0002-2643-0979","contributorId":2579,"corporation":false,"usgs":true,"family":"Cronin","given":"Thomas","email":"tcronin@usgs.gov","middleInitial":"M.","affiliations":[{"id":243,"text":"Eastern Geology and Paleoclimate Science Center","active":true,"usgs":true},{"id":40020,"text":"Florence Bascom Geoscience Center","active":true,"usgs":true}],"preferred":true,"id":488692,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Baker, Paul A.","contributorId":89446,"corporation":false,"usgs":true,"family":"Baker","given":"Paul","email":"","middleInitial":"A.","affiliations":[],"preferred":false,"id":488694,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Rodriguez-Lazaro, Julio","contributorId":105227,"corporation":false,"usgs":true,"family":"Rodriguez-Lazaro","given":"Julio","affiliations":[],"preferred":false,"id":488695,"contributorType":{"id":1,"text":"Authors"},"rank":4}]}}

They occur along convergent plate margins and are invariably associated directly with active faults and volcanism. They are complex in form, variable in their characteristics at all scales, and highly localized in the earth’s crust.\nMore than a century of detailed research has provided an extensive base of observational data characterizing these deposits, from their regional setting to the fluid and isotope chemistry of mineral deposition. This has led to a broad understanding of the large-scale hydrothermal systems within which they form. Low salinity vapor, released by magma crystallization and dispersed into vigorously convecting groundwater systems, is recognized as a principal source of metals and the gases that control redox conditions within systems. The temperature and pressure of the ambient fluid anywhere within these systems is close to its vapor-liquid phase boundary, and mineral deposition is a consequence of short timescale perturbations generated by localized release of crustal stress.\nHowever, a review of occurrence data raises questions about ore formation that are not addressed by traditional genetic models. For example, what are the origins of banding in epithermal veins, and what controls the frequency of oscillatory lamination? What controls where the phenomenon of mineralization occurs, and why are some porphyry deposits, for example, so much larger than others?\nThe distinctive, self-organized characteristics of epizonal deposits are shown to be the result of repetitive coupling of fracture dilation consequent on brittle failure, phase separation (“boiling”), and heat transfer between fluid and host rock. Process coupling substantially increases solute concentrations and triggers fast, far-from-equilibrium depositional processes. Since these coupled processes lead to localized transient changes in fluid characteristics, paragenetic, isotope, and fluid inclusion data relate to conditions at the site of deposition and only indirectly to the characteristics of the larger-scale hydrothermal system and its longer-term behavior. The metal concentrations (i.e. grade) of deposits and their internal variation is directly related to the geometry of the fracture array at the deposit scale, whereas finer-scale oscillatory fabrics in ores may be a result of molecular scale processes.\nGiant deposits are relatively rare and develop where efficient metal deposition is spatially focused by repetitive brittle failure in active fault arrays. Some brief case histories are provided for epithermal, replacement, and porphyry mineralization. These highlight how rock competency contrasts and feedback between processes, rather than any single component of a hydrothermal system, govern the size of individual deposits. In turn, the recognition of the probabilistic nature of mineralization provides a firmer foundation through which exploration investment and risk management decisions can be made.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Annual Review of Earth and Planetary Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Annual Reviews","doi":"10.1146/annurev.earth.28.1.669","usgsCitation":"Henley, R.W., and Berger, B.R., 2000, Self-ordering and complexity in epizonal mineral deposits: Annual Review of Earth and Planetary Sciences, v. 28, p. 669-719, https://doi.org/10.1146/annurev.earth.28.1.669.","productDescription":"54 p.","startPage":"669","endPage":"719","numberOfPages":"54","costCenters":[],"links":[{"id":281402,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281401,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1146/annurev.earth.28.1.669"}],"volume":"28","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7267e4b0b2908510847d","contributors":{"authors":[{"text":"Henley, Richard W.","contributorId":107193,"corporation":false,"usgs":true,"family":"Henley","given":"Richard","email":"","middleInitial":"W.","affiliations":[],"preferred":false,"id":489128,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Berger, Byron R. bberger@usgs.gov","contributorId":1490,"corporation":false,"usgs":true,"family":"Berger","given":"Byron","email":"bberger@usgs.gov","middleInitial":"R.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":489127,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Rates of vertical accretion and elevation change were similar in the older and mid-height settings on Scolt Head Island, indicating control of elevation change by surface accretionary processes (e.g. sediment deposition). However, subsurface processes controlled elevation at three of the marsh sites. Spartina Marsh, the youngest and lowest of the back barrier settings at Scolt Head Island, exhibited continuous shallow subsidence (vertical accretion greater than elevation change) over a 4-year period, implying that compaction controls elevation change. In the upper part of Hut Marsh and the interior of the Stiffkey marshes, elevation change exceeded vertical accretion suggesting that subsurface processes (e.g. organic accumulation) controlled elevation in these settings. Surface accretionary processes control elevation change in both the highly dynamic, outer marsh at Stiffkey and the low, restored marsh at Tollesbury. Despite the occurrence of shallow subsidence, all sites gained elevation at an annual rate comparable to that of sea-level rise. In summary, the SET provides the means to critically evaluate the influence of vertical accretion measures on elevation and represents an improved method by which to evaluate the vulnerability of a

That record indicates that the δ18O of the lake water, and by analogy its salinity, evolved through evaporation. Limited and less reliable data on hydrous minerals and fluid inclusions in early diagenetic carbonates indicate that the δD of the lake waters also evolved through evaporation. The isotope data place restrictions on models of the physical limnology of the lake and its evolution.</p><p>The closed-basin Lake Creede formed shortly after collapse of the 26.9 Ma Creede caldera. Throughout most of its history it occupied the northern three quarters of the moat between the resurgent dome and wall of the caldera. The Creede Formation was deposited in the basin, dominantly as lacustrine sediments. Travertine mounds interfinger with Creede Formation sediments along the inner and outer margins of the lake basin. An estimated one-half of the original thickness of the Creede Formation has been lost mainly to erosion although scattered remnants of the upper portion remain on the caldera walls. Two diamond core holes (CCM-1 and CCM-2) sampled the uneroded portion of the Creede Formation as part of the U.S. Continental Drilling Program. Volcaniclastic material, including tuff units deposited directly into the lake and ash washed in from the watershed, compose the main lithologies of the Creede Formation. These volcaniclastic strata were produced by episodic ring-fracture volcanism.</p><p>Lacustrine carbonates make up about 15% of the section sampled by drill core. They occur as 1 mm to 2 cm low-Mg calcite laminae alternating with siliciclastic laminae in scattered intervals throughout the preserved section. The carbonate laminae are accumulations of 5–20 µm crystallites (microsparites) and brine shrimp fecal pellets (peloids) composed mainly of microsparite particles. Low-Mg calcite also occurs as an early diagenetic replacement of gypsum or ikaite (CaCO3 ·6H2O) crystals grown displacively in the muds and silts near the water-sediment interface (rice grains). Other studies indicate that aragonite was the original CaCO3 precipitate forming the microsparite and peloidal laminae and that it converted to calcite during burial diagenesis. Samples from CCM-2 and nearby outcrop do not appear to have undergone significant isotope exchange during recrystallization. Samples from CCM-1 and nearby outcrop, however, appear to have undergone extensive oxygen isotope exchange with meteoric water-dominated fluids possibly during a local 17.6 Ma hydrothermal event.</p><p>The δ18O-δ13C data set produced by microsampling of individual carbonate lamellae and rice grains is exceptional in several aspects and provides important clues concerning the evolution of limnologic structure of the lake and its chemical and isotopic composition. Travertine and ikaite pseudomorphs in travertine deposits extend the record an additional 330 m above the collar of CCM-2. The δ18O values on CCM-2 samples range from 10.4‰ to 37.3‰ and δ13C values range from –10.8‰ to 9.6‰. The data fall into two distinct groups, a covariant group and an invariant group. The covariant group shows a strong negative covariance and a large range of δ18O and δ13C values. The negative covariance is opposite that normally reported for lacustrine carbonates. The large range of δ18O and δ13C values requires that the carbonates precipitated from waters have a large range of temperature and carbon and oxygen isotopic composition. The invariant group has a narrow range of large δ18O values (35‰ ± 2‰) and a wide range of δ13C values (–10.8‰ to 9.6‰), indicating precipitation from waters with a narrow range of temperature and δ18O but a wide range in δ13C of aqueous carbon. The ranges of isotope values for microsparite and peloid samples are virtually identical; two-thirds are in the covariant group. By contrast, the values for almost all rice grain samples are in the invariant group. The range in δ18O for all samples reflects precipitation from waters having varying proportions of deep, cold evaporated lake water and shallow, warmer meteoric water. The range for δ13C reflects varying proportions of organic carbon and carbon of volcanic or atmospheric origin, probably dominantly volcanic, in the aqueous carbon.</p><p>Changes in the detailed carbon-oxygen isotope systematics with stratigraphic position define three periods of isotopic evolution of Lake Creede. Period I is represented by the lowest ~200 m of Creede Formation core in CCM-2. Analyses of individual microsparite and peloidal carbonate laminae within single thin sections of samples from that interval are tightly grouped. The data set as a whole shows a negative covariance. Rice grains are not found in this interval. Period II is represented by the succeeding 120 m of core in CCM-2. In that interval, δ13C-δ18O values for individual microsparite and peloidal carbonate laminae within single thin sections show strong negative covariance, and the set of values for the entire interval also shows strong negative covariance. Rice grains occur near the top of the interval. Period III is represented by the upper 225 m of CCM-2 core. In this interval, rice grains are abundant and δ13C-δ18O values for microsparite and peloidal laminae as well as rice grains fall in the invariant group.</p><p>During Period I the lake was well mixed and the oxygen isotopic composition of the lake in the productive zone was only slightly influenced by short-term (e.g., annual) variations in the water budget of the lake. In Period II the lake was stratified, possibly with annual overturn. The productive zone included the mixolimnion and the isotopic composition of the microsparites and peloids reflected mixtures of shallow surface (meteoric) water containing volcanic or atmospheric CO2 (epilimnion) and cold underlying waters, the oxygen isotopic compositions of which had evolved through evaporation and were dominated by CO2 produced by the oxidation of organic matter (hypolimnion). During Period III the lake remained stratified. The productive zone was in the hypolimnion, probably due to a thinning of the epilimnion resulting from an increase in the surface area of the lake or a decrease in input waters reflecting a climate change. An upsection increase in values of δ18O for the heaviest samples during Periods I and II indicates evaporative concentration of 18O and, by analogy, salinity in the hypolimnion.</p><p>The δD-δ18O evolution of the lake is inferred on theoretical evaporation trends, comparison to Mono Lake, and measurement of the δD in fluid inclusions in a calcite pseudomorph after ikaite. The δD-δ18O composition of the lake water followed a curved path that eventually hooked over at a nearly constant δ18O value for the lake of 2‰ ± 2‰</p><p>Travertine (tufa) mounds formed along the inner and outer margins of the lake in a zone of mixing of warm, volcanic CO2-bearing, meteoric waters and lake water. Ikaite crystals formed on the mounds from unmixed saline lake water, probably below the thermocline. As the position of the thermocline deepened, likely following the spring runoff, the ikaite was replaced by calcite and the resulting “pearls” were covered with travertine deposited from mixed meteoric and lake waters.</p><p>The upsection increase in δ18O values of the carbonates, the long period of invariance of large δ18OH2O values, the presence of brine shrimp fecal pellets, and the inferred hooked δD-δ18O path are consistent with evidence from other studies that Lake Creede obtained significant salinity rather early in its history and certainly by the time the lake became permanently stratified.</p>","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"GSA Special Papers","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Geological Society of America","doi":"10.1130/0-8137-2346-9.233","usgsCitation":"Rye, R.O., Bethke, P., and Finkelstein, D., 2000, Stable isotope evolution and paleolimnology of ancient Lake Creede: GSA Special Papers, v. 346, p. 233-265, https://doi.org/10.1130/0-8137-2346-9.233.","productDescription":"33 p.","startPage":"233","endPage":"265","numberOfPages":"33","costCenters":[],"links":[{"id":282376,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282335,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1130/0-8137-2346-9.233"}],"country":"United States","state":"Colorado","city":"Creede","otherGeospatial":"Lake Creede","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -106.934323,37.841685 ], [ -106.934323,37.869147 ], [ -106.919627,37.869147 ], [ -106.919627,37.841685 ], [ -106.934323,37.841685 ] ] ] } } ] }","volume":"346","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd73e1e4b0b29085109352","contributors":{"authors":[{"text":"Rye, Robert O. rrye@usgs.gov","contributorId":1486,"corporation":false,"usgs":true,"family":"Rye","given":"Robert","email":"rrye@usgs.gov","middleInitial":"O.","affiliations":[{"id":211,"text":"Crustal Geophysics and Geochemistry Science Center","active":true,"usgs":true}],"preferred":true,"id":490213,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Bethke, Philip M.","contributorId":52829,"corporation":false,"usgs":true,"family":"Bethke","given":"Philip M.","affiliations":[],"preferred":false,"id":490214,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Finkelstein, David B.","contributorId":64687,"corporation":false,"usgs":true,"family":"Finkelstein","given":"David B.","affiliations":[],"preferred":false,"id":490215,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Milos Island is part of the active Aegean volcanic arc. A 1 km long basin located between two dacitic domes in northwest Milos is filled with a 35-50 m thick section of Quaternary volcaniclastic and pyroclastic rocks capped by reef limestone that were hydrothermally mineralized by Mn oxides and barite. Manganese occurs as thin layers, as cement of sandstone and as metasomatic replacement of the limestone, including abundant fossil shells. Manganese minerals include chiefly δ-MnO2, pyrolusite and ramsdellite. The MnO contents for single beds range up to 60%. The Mn oxide deposits are rich in Pb (to 3.4%), BaO (to 3.1%), Zn (to 0.8%), As (to 0.3%), Sb (to 0.2%) and Ag (to 10 ppm). Strontium isotopic compositions of the Mn oxide deposits and sulphur isotopic compositions of the associated barite show that the mineralizing fluids were predominantly sea water. The Mn oxide deposit formed in close geographical proximity to sulphide-sulphate-Au-Ag deposits and the two deposit types probably formed from the same hydrothermal system. Precipitation of Mn oxide took place at shallow burial depths and was promoted by the mixing of modified sea water (hydrothermal fluid) from which the sulphides precipitated at depth and sea water that penetrated along faults and fractures in the Cape Vani volcaniclastic and tuff deposits. The hydrothermal fluid was formed from predominantly sea water that was enriched in metals leached from the basement and overlying volcanogenic rocks. The hydrothermal fluids were driven by convection sustained by heat from cooling magma chambers. Barite was deposited throughout the time of Mn oxide mineralization, which occurred in at least two episodes. Manganese mineralization occurred by both focused and diffuse flow, the fluids mineralizing the beds of greatest porosity and filling dilatational fractures along with barite.","largerWorkType":{"id":2,"text":"Article"},"largerWorkTitle":"Applied Earth Sciences","largerWorkSubtype":{"id":10,"text":"Journal Article"},"language":"English","publisher":"Institute of Mining and Metallurgy","doi":"10.1179/aes.2000.109.2.67","usgsCitation":"Hein, J., Stamatakis, G., and Dowling, J., 2000, Trace metal-rich Quaternary hydrothermal manganese oxide and barite deposit, Milos Island, Greece: Applied Earth Sciences, v. 109, no. 2, p. 67-76, https://doi.org/10.1179/aes.2000.109.2.67.","productDescription":"10 p.","startPage":"67","endPage":"76","numberOfPages":"10","costCenters":[],"links":[{"id":281400,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":281399,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1179/aes.2000.109.2.67"}],"country":"Greece","otherGeospatial":"Milos Island","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ 24.317285,36.644784 ], [ 24.317285,36.774206 ], [ 24.547792,36.774206 ], [ 24.547792,36.644784 ], [ 24.317285,36.644784 ] ] ] } } ] }","volume":"109","issue":"2","noUsgsAuthors":false,"publicationDate":"2013-07-18","publicationStatus":"PW","scienceBaseUri":"53cd7972e4b0b2908510cd19","contributors":{"authors":[{"text":"Hein, J.R. 0000-0002-5321-899X","orcid":"https://orcid.org/0000-0002-5321-899X","contributorId":61429,"corporation":false,"usgs":true,"family":"Hein","given":"J.R.","affiliations":[],"preferred":false,"id":489125,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Stamatakis, G.","contributorId":9959,"corporation":false,"usgs":true,"family":"Stamatakis","given":"G.","email":"","affiliations":[],"preferred":false,"id":489124,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Dowling, J.S.","contributorId":72443,"corporation":false,"usgs":true,"family":"Dowling","given":"J.S.","email":"","affiliations":[],"preferred":false,"id":489126,"contributorType":{"id":1,"text":"Authors"},"rank":3}]}}

Of less certainty is the extent to which regional scale (i.e., sub-GCM grid) environmental processes will be affected. In this chapter, a range of downscaling techniques are critiqued. Then a relatively simple (yet robust) statistical downscaling technique and its use in the modelling of future runoff scenarios for three river basins in the Sierra Nevada, California, is described. This region was selected because GCM experiments driven by combined greenhouse-gas and sulphate-aerosol forcings consistently show major changes in the hydro-climate of the southwest United States by the end of the 21st century. The regression-based downscaling method was used to simulate daily rainfall and temperature series for streamflow modelling in three Californian river basins under current-and future-climate conditions. The downscaling involved just three predictor variables (specific humidity, zonal velocity component of airflow, and 500 hPa geopotential heights) supplied by the U.K. Meteorological Office couple ocean-atmosphere model (HadCM2) for the grid point nearest the target basins. When evaluated using independent data, the model showed reasonable skill at reproducing observed area-average precipitation, temperature, and concomitant streamflow variations. Overall, the downscaled data resulted in slight underestimates of mean annual streamflow due to underestimates of precipitation in spring and positive temperature biases in winter. Differences in the skill of simulated streamflows amongst the three basins were attributed to the smoothing effects of snowpack on streamflow responses to climate forcing. The Merced and American River basins drain the western, windward slope of the Sierra Nevada and are snowmelt dominated, whereas the Carson River drains the eastern, leeward slope and is a mix of rainfall runoff and snowmelt runoff. Simulated streamflow in the American River responds rapidly and sensitively to daily-scale temperature and precipitation fluctuations and errors; in the Merced and Carson Rivers, the response to the same short-term influences is much less. Consequently, the skill of simulated flows was significantly lower in the American River model than in the Carson and Merced. The physiography of the three basins also accounts for differences in their sensitivities to future climate change. Increases in winter precipitation exceeding +100% coupled with mean temperature rises greater than +2&deg;C result in increased winter streamflows in all three basins. In the Merced and Carson basins, these streamflow increases reflect large changes in winter snowpack, whereas the streamflow changes in the lower elevation American basin are driven primarily by rainfall runoff. Furthermore, reductions in winter snowpack in the American River basin, owing to less precipitation falling as snow and earlier melting of snow at middle elevations, lead to less spring and summer streamflow. Taken collectively, the downscaling results suggest significant changes to both the timing and magnitude of streamflows in the Sierra Nevada by the end of the 21st Century. In the higher elevation basins, the HadCM2 scenario implies more annual streamflow and more streamflow during the spring and summer months that are critical for water-resources management in California. Depending on the relative significance of rainfall runoff and snowmelt, each basin responds in its own way to regional climate forcing. Generally, then, climate scenarios need to be specified &mdash; by whatever means &mdash; with sufficient temporal and spatial resolution to capture subtle orographic influences if projections of climate-change responses are to be useful and reproducible.</p>","largerWorkType":{"id":4,"text":"Book"},"largerWorkTitle":"Linking climate change to land surface change","largerWorkSubtype":{"id":4,"text":"Other Government Series"},"language":"English","publisher":"Springer","doi":"10.1007/0-306-48086-7_6","isbn":"978-0-306-48086-7","usgsCitation":"Wilby, R.L., and Dettinger, M., 2000, Streamflow changes in the Sierra Nevada, California, simulated using a statistically downscaled general circulation model scenario of climate change, chap. <i>of</i> Linking climate change to land surface change, v. 6, p. 99-121, https://doi.org/10.1007/0-306-48086-7_6.","productDescription":"23 p.","startPage":"99","endPage":"121","numberOfPages":"23","onlineOnly":"N","additionalOnlineFiles":"N","costCenters":[{"id":552,"text":"San Francisco Bay-Delta","active":false,"usgs":true},{"id":5079,"text":"Pacific Regional Director's Office","active":true,"usgs":true}],"links":[{"id":282436,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"},{"id":282435,"type":{"id":10,"text":"Digital Object Identifier"},"url":"https://dx.doi.org/10.1007/0-306-48086-7_6"}],"country":"United States","state":"California","otherGeospatial":"Sierra Nevada","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -119.886496,37.494762 ], [ -119.886496,38.185228 ], [ -119.195416,38.185228 ], [ -119.195416,37.494762 ], [ -119.886496,37.494762 ] ] ] } } ] }","volume":"6","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd7493e4b0b290851099eb","contributors":{"authors":[{"text":"Wilby, Robert L.","contributorId":101561,"corporation":false,"usgs":true,"family":"Wilby","given":"Robert","email":"","middleInitial":"L.","affiliations":[],"preferred":false,"id":490412,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Dettinger, Michael D. 0000-0002-7509-7332","orcid":"https://orcid.org/0000-0002-7509-7332","contributorId":31743,"corporation":false,"usgs":true,"family":"Dettinger","given":"Michael D.","affiliations":[],"preferred":false,"id":490411,"contributorType":{"id":1,"text":"Authors"},"rank":2}]}}

Since becoming operational in October of 1996 through the\ntransfer of programs from various bureaus within the Department of the Interior, the BRD, in\ncooperation with other Federal, State, and local partners, has begun research, inventory and\nmonitoring, information sharing, and technology transfer. Through these activities, the BRD is\nfostering an understanding of biological systems and their benefits to society, and providing the\nessential scientific support and technical assistance required for management and policy decisions.\nThe role of BRD' s National Wetlands Research Center (NWRC) in Lafayette, Louisiana, with\nproject offices in Baton Rouge, LA and Gulf Breeze, FL, is to provide leadership in research and\ndevelopment related to the Nation's natural resources for the Southeast. The research focuses on\nwetlands ecology, animal ecology, and the development and application of spatial analysis\ntechniques for natural resource related studies.\nCurrent geographic information system (GIS) technologies in use at NWRC are designed to provide\nnatural resource managers with the on-line data and computerized techniques necessary to make\ninformed decisions. Major GIS activities at NWRC include: compilation and analysis of digital\ndatabases for monitoring of natural resources; integration and transfer of databases with existing\ndigital databases from various sources into a comprehensive GIS; and development of\nmultifunctional decision support systems for natural resource managers using these data. NWRC is\nalso an active participant in the National Information Infrastructure (NIT), in particular the National\nSpatial Data Infrastructure (NSDI) and the National Biological Information Infrastructure (NBTI),\nwhich will facilitate the dissemination of research results and other knowledge and information\ngained from these efforts.

This field trip will examine the regional geologic and hydrologic setting for Yucca Mountain, as well as specific results of the site characterization program. The first day focuses on the regional setting with emphasis on current and paleo hydrology, which are both of critical concern for predicting future performance of a potential repository. Morning stops will be southern Nevada and afternoon stops will be in Death Valley. The second day will be spent at Yucca Mountain. The field trip will visit the underground testing sites in the \"Exploratory Studies Facility\" and the \"Busted Butte Unsaturated Zone Transport Field Test\" plus several surface-based testing sites. Much of the work at the site has concentrated on studies of the unsaturated zone, an element of the hydrologic system that historically has received little attention. Discussions during the second day will compromise selected topics of Yucca Mountain geology, hydrology and geochemistry and will include the probabilistic volcanic hazard analysis and the seismicity and seismic hazard in the Yucca Mountain area. Evening discussions will address modeling of regional groundwater flow, the results of recent hydrologic studies by the Nye County Nuclear Waste Program Office, and the relationship of the geology and hydrology of Yucca Mountain to the performance of a potential repository. Day 3 will examine the geologic framework and hydrology of the Pahute Mesa-Oasis Valley Groundwater Basin and then will continue to Reno via Hawthorne, Nevada and the Walker Lake area.","language":"English","publisher":"Geological Society of America","doi":"10.1130/0-8137-0002-7.383","usgsCitation":"Levich, R., Linden, R., Patterson, R., and Stuckless, J., 2000, Hydrologic and geologic characteristics of the Yucca Mountain site relevant to the performance of a potential repository: GSA Field Guides, v. 2, p. 383-414, https://doi.org/10.1130/0-8137-0002-7.383.","productDescription":"32 p.","startPage":"383","endPage":"414","numberOfPages":"32","costCenters":[],"links":[{"id":281259,"type":{"id":24,"text":"Thumbnail"},"url":"https://pubs.usgs.gov/thumbnails/outside_thumb.jpg"}],"country":"United States","state":"Nevada","otherGeospatial":"Yucca Mountain","geographicExtents":"{ \"type\": \"FeatureCollection\", \"features\": [ { \"type\": \"Feature\", \"properties\": {}, \"geometry\": { \"type\": \"Polygon\", \"coordinates\": [ [ [ -117.0,36.0 ], [ -117.0,37.0 ], [ -115.0,37.0 ], [ -115.0,36.0 ], [ -117.0,36.0 ] ] ] } } ] }","volume":"2","noUsgsAuthors":false,"publicationStatus":"PW","scienceBaseUri":"53cd615ee4b0b290850fd7c7","contributors":{"authors":[{"text":"Levich, R.A.","contributorId":68553,"corporation":false,"usgs":true,"family":"Levich","given":"R.A.","affiliations":[],"preferred":false,"id":488909,"contributorType":{"id":1,"text":"Authors"},"rank":1},{"text":"Linden, R.M.","contributorId":66007,"corporation":false,"usgs":true,"family":"Linden","given":"R.M.","email":"","affiliations":[],"preferred":false,"id":488908,"contributorType":{"id":1,"text":"Authors"},"rank":2},{"text":"Patterson, R.L.","contributorId":24272,"corporation":false,"usgs":true,"family":"Patterson","given":"R.L.","email":"","affiliations":[],"preferred":false,"id":488907,"contributorType":{"id":1,"text":"Authors"},"rank":3},{"text":"Stuckless, J.
