Benthic Community and Bivalve Metrics Data in the Sacramento - San Joaquin Delta from 2015 to 2018 Benthic Community and Bivalve Metrics Data in the Sacramento - San Joaquin Delta from 2015 to 2018
Declining phytoplankton biomass and the resulting stress on the food web has been suggested as one contributor to the decline of Delta Smelt and other fish species in the San Francisco Bay (SFB) and the Sacramento San Joaquin River Delta. Filter feeding by two species of bivalves, Corbicula fluminea and Potamocorbula amurensis, has been shown to control phytoplankton growth rate in the...
Benthic Foraminiferal Data from Surface Samples and Sedimentary Cores in the Grand Bay Estuary, Mississippi and Alabama Benthic Foraminiferal Data from Surface Samples and Sedimentary Cores in the Grand Bay Estuary, Mississippi and Alabama
Microfossil (benthic foraminifera) samples were obtained from surficial grab (denoted with 'G') and push core (denoted with 'M') sediments collected in Grand Bay estuary, Mississippi and Alabama, to aid in the paleoenvironmental understanding of Grand Bay estuary. The data presented here were collected as part of the U.S. Geological Survey's Sea-level and Storm Impacts on Estuarine...
Benthic infaunal communities of Baltimore and Norfolk canyons Benthic infaunal communities of Baltimore and Norfolk canyons
Submarine canyons are morphologically complex systems, acting as major conduits of organic matter along continental shelves, promoting gradients in food resources, habitat heterogeneity, and areas of sediment resuspension and deposition. Often environmental conditions within canyons can be highly distinct, particularly in different parts of the canyon and in contrast to adjacent slopes...
Bighorn sheep Ovine HD array genotypes from National Parks, 2004-2011 Bighorn sheep Ovine HD array genotypes from National Parks, 2004-2011
Between 2004 and 2011 bighorn sheep were darted in Glacier National Park and in Dinosaur National Monument. Blood was drawn. These are the genotypes resulting from an Ovine HD array from the bighorns. The first 3 columns refers to bighorn sheep identifiers: 'Herd_Unit', 'IndID', and 'AgencyID'. IndID is the identifier assigned at Montana State University. Subsequent columns each...
Bile acid concentrations in tissues of American eel that were held at Northern Appalachian Research Laboratory, Wellsboro, Pennsylvania, as derived from liquid chromatography coupled to tandem mass spectrometry Bile acid concentrations in tissues of American eel that were held at Northern Appalachian Research Laboratory, Wellsboro, Pennsylvania, as derived from liquid chromatography coupled to tandem mass spectrometry
The American eel (Anguilla rostrata) is an imperiled fish hypothesized to use conspecific cues, in part, to coordinate long distance migration during their multi-stage life history. Here, tissues from multiple American eel life stages were collected and analyzed for the presence and concentration of bile acids. Specifically, samples were collected in the Northern Appalachian Research...
Bio-engineered oyster reef monitoring, Eloi Bay, Louisiana, 2017-2019 Bio-engineered oyster reef monitoring, Eloi Bay, Louisiana, 2017-2019
This dataset includes annual encrusting organism (oyster, mussel, barnacle) counts and density (ind m-2), and oyster shell height (mm) data for five bio-engineered reef designs: OysterbreakTM (OB), Wave Attenuating Device (WAD), Reef Ball (rows of two, RFB2; rows of three, RFB3), ReefBLK? (RBL), and ShoreJAX (JAX). Data were collected during winter months (i.e., December-January) in 2017...
Bioelectrical Impedance, Deuterium Dilution, Body Mass, and Morphological Measures of Southern Beaufort Sea Female Polar Bears, Spring 2014-2016 Bioelectrical Impedance, Deuterium Dilution, Body Mass, and Morphological Measures of Southern Beaufort Sea Female Polar Bears, Spring 2014-2016
This dataset contains data from the use of bioelectrical impedance analysis and deuterium injection as methods to estimate the body composition of female polar bears in the southern Beaufort Sea subpopulation. Data are provided on bioelectrical impedance resistance measures, the enrichment level of deuterium oxide that was injected and measured in blood samples, and morphological...
Biogeochemical Data for Mercury and other Constituents in Surface Sediment and Deep Cores from the Hells Canyon Reservoir Complex, Idaho and Oregon 2014-2018 Biogeochemical Data for Mercury and other Constituents in Surface Sediment and Deep Cores from the Hells Canyon Reservoir Complex, Idaho and Oregon 2014-2018
The Hells Canyon Complex (HCC) is comprised of a series of three consecutive reservoirs (Brownlee, Oxbow, and Hells Canyon) along a 145 km reach of the Snake River bordered by Idaho to the east and Oregon to the west. Due to concerns regarding mercury (Hg) contamination within the HCC, in cooperation with Idaho Power Company, the U.S. Geological Survey has been leading an investigation...
Bird Behavior and Mortality in Relation to Power Lines in Prairie Habitats, North Dakota, 1981to1982 Bird Behavior and Mortality in Relation to Power Lines in Prairie Habitats, North Dakota, 1981to1982
A biologist and field crew from Northern Prairie Wildlife Research Center observed bird flights at 7study sites, twice weekly during two spring and two fall migration periods between April 3, 1981 and May 20, 1982. Study sites were located in south-central North Dakota in Barnes, Kidder, and Stutsman counties. The database includes flight observation's of bird species in the vicinity of...
Blank results for trace-element data collected for the California Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project, October 2009-October 2018 Blank results for trace-element data collected for the California Groundwater Ambient Monitoring and Assessment (GAMA) Program Priority Basin Project, October 2009-October 2018
Groundwater samples have been collected in California as part of statewide investigations of groundwater quality conducted by the U.S. Geological Survey for the Groundwater Ambient Monitoring and Assessment (GAMA) Priority Basin Project (PBP). Quality-control samples are routinely collected as part of the GAMA-PBP quality assurance plan. Olsen and others (2010) and Davis and others (2014...
Body condition score of horses wearing radio collars, weekly behavior data of treatments and controls, and monthly descriptive data of collar and radio tag effects, 2015-2016, Oklahoma, USA Body condition score of horses wearing radio collars, weekly behavior data of treatments and controls, and monthly descriptive data of collar and radio tag effects, 2015-2016, Oklahoma, USA
These data are from a study of wild horses and burros wearing radio collars in a captive facility in Oklahoma, USA, for one year. We also evaluated radio transmitter tags (braided into the mane and tails of horses but not burros). We recorded behavior, body condition score, and effects of collars on the necks of horses and burros wearing radio collars and of horses and burros not wearing...
Boreal toad metamorph capture, recapture and covariates data, Colorado 2017-2018 Boreal toad metamorph capture, recapture and covariates data, Colorado 2017-2018
