Benthic algae and plankton occurrence information to support environmental DNA surveys at nine selected sites the Tualatin River Basin Benthic algae and plankton occurrence information to support environmental DNA surveys at nine selected sites the Tualatin River Basin
Dataset includes qualitative benthic algae and plankton occurrence data from 148 discrete samples of plankton (n=58) collected with an 80-micron mesh plankton net and streambed sediment (n=90) collected using a pipettor and(or) petri dish and spatula. Samples were collected, placed on ice, and analyzed within 1-3 days. Multiple wet mount slides were prepared and examined with a Leica...
Biliary PAHs in white perch collected in Chesapeake Bay and Albemarle Sound, North Carolina, 2022-2023 Biliary PAHs in white perch collected in Chesapeake Bay and Albemarle Sound, North Carolina, 2022-2023
Biliary concentrations of naphthalene, phenanthrene, and benzo[a]pyrene equivalents measured in white perch (Morone americana) collected in Chesapeake Bay (April to August 2022) and Albemarle Sound, NC (March 2023). Data include measured concentrations in each sample and associated QA/QC measurements for analytical chemistry.
Biological and Chemical Findings Associated with Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus from Selected Northeast United States and Quebec Waterbodies Biological and Chemical Findings Associated with Melanoma and Other Melanistic Lesions in Brown Bullhead Ameiurus nebulosus from Selected Northeast United States and Quebec Waterbodies
Brown bullhead were collected from seven sites in Lake Memphremagog in Vermont and Quebec, Hermon Pond in Maine and Village Pond in New Hampshire. Both visibly normal and lesioned adult bullhead were collected at each site. Biological data collected included length, weight, sex, age, condition factor and presence or absence of non-raised and raised black lesions. Plasma from five sites...
Biological soil crust and vegetation cover from two previously grazed grasslands within Canyonlands National Park, Utah Biological soil crust and vegetation cover from two previously grazed grasslands within Canyonlands National Park, Utah
These tabular data were compiled to monitor vegetation and biocrust cover two previously grazed grassland located in the Needles District of Canyonlands National Park. Objectives of this study are to document potential changes in biological soil crust (biocrust) and vegetation cover and species composition over time and with ongoing U.S. National Park Service (NPS) management. These data...
Bird dataset from point counts at 2023 CASC and NPS field sites in the Sky Islands and Mogollon Plateau, U.S. and Mexico Bird dataset from point counts at 2023 CASC and NPS field sites in the Sky Islands and Mogollon Plateau, U.S. and Mexico
This dataset field sampling of bird communities based on standardized point count methods with distance sampling. University of Arizona field crews gathered all data using 8-minute point counts, with stations placed 200-300 m apart along transects.
Blotchy Bass Syndrome (BBS) Citizen Science Surveillance Data, North America, 2022–2024 Blotchy Bass Syndrome (BBS) Citizen Science Surveillance Data, North America, 2022–2024
This data release contains quality-controlled records of angler-submitted observations of black bass (Micropterus spp.) collected through a two-year citizen science initiative using the MyCatch mobile application. The dataset includes verified catch records for largemouth bass and smallmouth bass, with each entry providing information on catch date, time, location (latitude/longitude)...
Bluegill Size Structure and Growth Data for Six States in the Midwestern USA Bluegill Size Structure and Growth Data for Six States in the Midwestern USA
Bluegill length and age data from standardized surveys conducted during 2000-2021 were obtained from Indiana, Illinois, Iowa, Michigan, Wisconsin and Minnesota through direct requests. Some data were obtained through collaboration with Dr. Gretchen Hansen at the University of Minnesota. These data were used to calculate proportional size distribution (PSD), mean total length (TL) at age...
Braiding Index Measurements, Río Coca, Ecuador, 2012–2023 Braiding Index Measurements, Río Coca, Ecuador, 2012–2023
On February 2, 2020, the Río Coca in Ecuador undermined a basaltic-andesitic lava dam that formed the 144-meter-high San Rafael waterfall. Following the failure of the lava dam, the sudden loss of grade control prompted rapid knickpoint retreat and regressive erosion into poorly consolidated sediment, which initially migrated tens of meters upstream per day. On February 25, 2021, the...
Brown treesnake 2009 supplemental feeding data and 2008-2012 capture mark recapture data from a closed population on Guam Brown treesnake 2009 supplemental feeding data and 2008-2012 capture mark recapture data from a closed population on Guam
The two datasets consist of capture-mark-recapture (cmr) data for brown treesnakes (Bioga irregularis), and a database containing information about supplemental food added to the population in 2009. The cmr data were collected in the closed population (CP) on Andersen Air Force Base in Guam. These data were used to assess how the population growth rate was affected by two perturbations...
Calculation of CFFDRS Fire Weather Indices in Boreal North America Using Bias-Corrected CMIP6 Calculation of CFFDRS Fire Weather Indices in Boreal North America Using Bias-Corrected CMIP6
This data release contains Canadian Forest Fire Danger Rating System (CFFDRS) fire weather indices calculated using bias-corrected CMIP6 daily data for the period of 1980 - 2100. The spatial domain includes the boreal ecoregion of North America.
Calibration data from Mount Hamilton, California, for USGS Volcano Science Center gravimeters Calibration data from Mount Hamilton, California, for USGS Volcano Science Center gravimeters
Temporal changes in gravity, also called microgravity in volcano geodesy and exploration geophysics applications, provide a means of measuring mass change beneath the surface—for example, due to the accumulation or withdrawal of water, magma, or other fluids. Relative spring-based gravimeters, however, require calibration to establish consistency between instruments, and to assess...
California 270-meter Basin Characterization Model using Weather Generator Scenarios, Part I - Monthly Climate and Hydrology California 270-meter Basin Characterization Model using Weather Generator Scenarios, Part I - Monthly Climate and Hydrology
This data release includes the downscaled climate inputs from twenty-four Weather Generator Scenarios and hydrologic outputs using the Basin Characterization Model (BCM) version 8 (v8), described in Flint and others (2021a), with a 270 by 270-meter spatial resolution at a monthly time steps from water years 1916 to 2018 for California. The twenty-four Weather Generator scenarios are...
