Shed viral load and survival of spring-run and fall-run Columbia River Basin Chinook salmon exposed to 3 genogroups of infectious hematopoietic necrosis virus (IHNV) Shed viral load and survival of spring-run and fall-run Columbia River Basin Chinook salmon exposed to 3 genogroups of infectious hematopoietic necrosis virus (IHNV)
This investigation sought to characterize the shedding of infectious hematopoietic necrosis virus (IHNV) in two populations of Columbia River Basin (CRB) Chinook salmon (Oncorhynchus tshawytscha). Juvenile spring- and fall-run Chinook salmon were exposed by immersion to each of three IHN virus strains from the UC, MD, and L subgroups, and then monitored for viral shedding from individual...
Meteorological data from Pea Island National Wildlife Refuge, North Carolina, 9/13/2021 to 10/24/2021 Meteorological data from Pea Island National Wildlife Refuge, North Carolina, 9/13/2021 to 10/24/2021
Meteorological data were collected as part of the DUring Nearshore Event eXperiment (DUNEX) on Pea Island National Wildlife Refuge in North Carolina during 2021. The DUNEX project is a collaborative, multi-agency experiment designed to provide comprehensive measurements of storm-induced processes on coastal habitats. The overarching goals of this study are to understand oceanographic...
Data Release for Holocene Paleohydrology from alpine lake sediment, Emerald Lake, Wasatch Plateau of central Utah, USA Data Release for Holocene Paleohydrology from alpine lake sediment, Emerald Lake, Wasatch Plateau of central Utah, USA
Holocene sediments at Emerald Lake in central Utah (3090 m a.s.l), document the paleohydroclimatic history of the western Upper Colorado River headwater region. Multi-proxy analyses of sediment composition, mineralogy, and stable isotopes of carbonate (d18O and d13C) show changes in effective moisture for the past ca. 10,000 years at millennial to decadal timescales. Emerald Lake...
Aerial imagery and structure-from-motion data products from a UAS survey of the Los Padres Reservoir delta, Carmel River valley, CA, 2017-11-01 Aerial imagery and structure-from-motion data products from a UAS survey of the Los Padres Reservoir delta, Carmel River valley, CA, 2017-11-01
An unoccupied aerial system (UAS) was used to acquire high-resolution imagery of the exposed reservoir delta at Los Padres Reservoir, in the Carmel River valley in central California on 1 November 2017. This survey followed sediment delivery to the reservoir by the Carmel River due to landscape response after the 2016 Soberanes Fire and high flows in winter 2017. The imagery from this...
GIS Data for Geologic Map of Precambrian Metasedimentary Rocks of The Medicine Bow Mountains, Albany and Carbon Counties, Wyoming GIS Data for Geologic Map of Precambrian Metasedimentary Rocks of The Medicine Bow Mountains, Albany and Carbon Counties, Wyoming
This U.S. Geological Survey (USGS) data release provides a digital geospatial database for the geologic map of Precambrian metasedimentary rocks of the Medicine Bow Mountains, Albany and Carbon Counties, Wyoming (Houston and Karlstrom, 1992). Attribute tables and geospatial features (points, lines and polygons) conform to the Geologic Map Schema (GeMS, 2020) and represent the geologic...
Rainbow trout growth data and growth covariate data from Glen Canyon, Colorado River, Arizona, 2012-2021 Rainbow trout growth data and growth covariate data from Glen Canyon, Colorado River, Arizona, 2012-2021
These data are the primary data used to model rainbow trout growth in Glen Canyon. Fish growth data were collected from nighttime boat electrofishing field campaigns conducted five to six times per year in April, July, September, and January, from April 2012 through November 2021 for a total of 9798 observations of mark-recapture-based growth. Sampling was conducted in a five km reach in...
Data describing vulnerability of Pacific salmon to invasion of northern pike (Esox lucius) in southcentral Alaska, 2017-2019 Data describing vulnerability of Pacific salmon to invasion of northern pike (Esox lucius) in southcentral Alaska, 2017-2019
The shapefile contains the data necessary to recreate the analyses used in Jalbert et al., in review, Vulnerability of Pacific salmon to invasion of northern pike (Esox lucius) in southcentral Alaska. Specifically, users will be able to view 1) intrinsic potential model calculations for 5 Pacific salmonids (Chinook, chum, pink, sockeye, and coho salmon) and northern pike and 2) all...
Sagebrush (Artemisia spp.) scale of effect for Greater Sage-grouse (Centrocercus urophasianus) population trends in southwest Wyoming, USA 2003-2019 Sagebrush (Artemisia spp.) scale of effect for Greater Sage-grouse (Centrocercus urophasianus) population trends in southwest Wyoming, USA 2003-2019
The distance within which populations respond to features in a landscape (scale of effect) can indicate how disturbance and management may affect wildlife. Using annual counts of male Greater Sage-grouse (Centrocercus urophasianus) attending 584 leks in southwest Wyoming (2003-2019) and estimates of sagebrush cover from the Rangeland Condition Monitoring Assessment and Projection (RCMAP)...
Emerging contaminant data at wastewater treatment facilities, municipal water supplies, surface water and lake sites in the northeastern United States, 2009-2018 (ver. 1.1, January 2023) Emerging contaminant data at wastewater treatment facilities, municipal water supplies, surface water and lake sites in the northeastern United States, 2009-2018 (ver. 1.1, January 2023)
Over 300 samples were collected in New York, Vermont, and Massachusetts from wastewater treatment facilities (20 locations), drinking water facilities (9 locations), streams (53 locations), lakes (2 locations), a bay (1 location), and a POCIS (Polar Organic Chemical Integrative Sampler) blank sample between April 2009 and October 2018. This data release provides chemistry data for over...
PFAS, pesticide, and pharmaceutical concentrations in the Bronx River, New York, 2019 (ver. 1.1, January 2023) PFAS, pesticide, and pharmaceutical concentrations in the Bronx River, New York, 2019 (ver. 1.1, January 2023)
This U.S. Geological Survey Data Release provides surface-water and bed sediment quality data at the Bronx River, New York, 2019. The data were collected with support from the Urban Waters Federal Partnership (UWFP) and others. Surface-water samples were collected at six locations along the Bronx River and analyzed for poly- and perfluoroalkyl substances (PFAS), pharmaceuticals, and...
Total mercury, bulk density, percent organic matter, and percent organic carbon measured in permafrost cores from the interior and northern slope of Alaska and previously published studies Total mercury, bulk density, percent organic matter, and percent organic carbon measured in permafrost cores from the interior and northern slope of Alaska and previously published studies
This data release contains two datasets (see child items below). The first dataset, "MasterDB-csv-published-final.csv", includes 11,000 published measurements of sediment total mercury (STHg, nanograms per gram of soil, dry), bulk density (BD, grams per cm3 of soil, dry), percent of soil organic matter (%OM, loss on ignition, LOI), percent of soil organic carbon (%SOC, calculated using...
Water quality sites indexed to NHDPlus v2.1 flowlines for the 2012 and the 2017 periods of the U.S. Geological Survey's Surface Water Status and Trends project Water quality sites indexed to NHDPlus v2.1 flowlines for the 2012 and the 2017 periods of the U.S. Geological Survey's Surface Water Status and Trends project
This data release provides a list of 2,304 water-quality sampling sites indexed to NHDPlus v2.1 flowlines along with the verified ComIDs. ComIDs are the unique identifiers for NHDPlus flowlines and allow the sites to be joined to ancillary and watershed information from other sources published for that purpose. The sites include those assembled for the period 1972-2012 by the U.S...
