Validating daily age via lapilli otolith growth rings in larval Grass Carp Ctenopharyngodon idella Validating daily age via lapilli otolith growth rings in larval Grass Carp Ctenopharyngodon idella
Accurate age estimation is crucial for understanding fish population dynamics, yet daily age validation for invasive Grass Carp in the Midwestern U.S. is lacking. We validated daily otolith increment deposition in known-age Grass Carp reared in laboratory and pond environments. Larval Grass Carp from captive broodstock were sampled between 6- and 120-days post-hatch. Lapilli otoliths...
Vegetation and soil moisture data from 2019 selective mortality experiment in perennial grassland on the Colorado Plateau, Utah, USA Vegetation and soil moisture data from 2019 selective mortality experiment in perennial grassland on the Colorado Plateau, Utah, USA
These data were compiled to investigate competitive interactions between Pleurphis jamesii and other herbaceous plants in a semiarid grassland community. The objectives of our study were to determine whether selective mortality of either C3 or C4 herbaceous plants led to changes in (1) soil moisture during the growing season, (2) water use by Pleuraphis jamesii during the growing season...
Geospatial datasets of seabed topography, sediment mobility, and the distribution of geologic substrates in quadrangle 3 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts Geospatial datasets of seabed topography, sediment mobility, and the distribution of geologic substrates in quadrangle 3 of the Stellwagen Bank National Marine Sanctuary region offshore of Boston, Massachusetts
The U.S. Geological Survey (USGS), in cooperation with the National Marine Sanctuary Program of the National Oceanic and Atmospheric Administration (NOAA), has conducted seabed mapping and related research in the Stellwagen Bank National Marine Sanctuary (SBNMS) region since 1993. The interpretive datasets and source information presented here are for quadrangle 3, which is one of 18...
A Generalized Hydrologic Stream Network (GenNet) of the Conterminous United States A Generalized Hydrologic Stream Network (GenNet) of the Conterminous United States
A generalized hydrologic stream network (GenNet) consisting of 263,494 generalized flowlines, inclusive of coastline and terminating flow paths, was constructed for the conterminous United States (CONUS) to support efficient dynamic modeling of nutrient loads, streamflow, and downstream transport of other contaminants in streams. GenNet was generalized from the base network E3NHDPlusV2...
Digital data of structural and isopach features derived from previously published Black Warrior Basin studies Digital data of structural and isopach features derived from previously published Black Warrior Basin studies
The Black Warrior Basin is a sedimentary foreland basin in western Alabama and northern Mississippi. This basin is named after the Black Warrior River and is developed extensively for coal, coalbed methane, conventional oil, and natural gas production. Its geologic genesis was due to Paleozoic tectonic events between the Appalachian and Ouachita orogenic belts. The Paleozoic rock hosts...
Whole rock geochemistry data from Mesoproterozoic rocks in the Paradox Lake quadrangle, Essex County, New York Whole rock geochemistry data from Mesoproterozoic rocks in the Paradox Lake quadrangle, Essex County, New York
This data release includes whole rock (WR) geochemical data. Bureau Veritas Commodities Canada Ltd. Laboratories in Vancouver, British Columbia, Canada analyzed the samples. Meghan Toft and Greg Walsh collected the rock samples from outcrops in the 7.5-minute Paradox Lake quadrangle, New York. The whole rock geochemistry data constrain the composition of mapped rocks in the eastern...
Collection, analysis, and age-dating of sediment cores from coastal wetlands in Oyster Bay, Alabama, 2021 Collection, analysis, and age-dating of sediment cores from coastal wetlands in Oyster Bay, Alabama, 2021
To assess historical environment changes associated with changes in hydrologic connection to the Gulf Intracoastal Waterway (GIW) and Mobile Bay, six sediment cores (50-80 cm in length) were collected in 2021 from two coastal wetland sites. These two sites in Gulf Shores, Alabama were: Oyster Bay Nature Preserve ("OB", a brackish marsh with natural hydrology) and the Emmet O. and Vina...
USGS National Shoreline Change - A compilation of published shoreline change rates (1800s-2010s) for the contiguous United States USGS National Shoreline Change - A compilation of published shoreline change rates (1800s-2010s) for the contiguous United States
The U.S. Geological Survey (USGS) maintains shoreline positions for the United States coasts from both older sources, such as aerial photos or topographic surveys, as well as contemporary sources like lidar elevation point clouds and digital elevation models (DEMs). These shorelines are compiled and analyzed in the Digital Shoreline Analysis System (DSAS) software to compute rates of...
Invasive carp environmental DNA data from the Blackwater and Lamine rivers, Missouri, 2015 Invasive carp environmental DNA data from the Blackwater and Lamine rivers, Missouri, 2015
Data describe environmental DNA (eDNA) concentrations from invasive silver and bigheaded carp (Hypophthalmichthys spp.) in Missouri’s Blackwater and Lamine Rivers in 2015. Two, 3-day sampling trips were conducted in March and September 2015 (winter and summer samples, respectively) to collect water samples and associated water quality data. Parameters include locations of collected water...
Environmental DNA shedding and degradation rates of Epioblasma capsaeformis in a laboratory setting Environmental DNA shedding and degradation rates of Epioblasma capsaeformis in a laboratory setting
Data describe designed environmental DNA (eDNA) experiments for the estimation of eDNA shedding and degradation rates for the Oyster Mussel (Epioblasma capsaeformis) at different biomass densities from water samples collected in the laboratory. A total of 12 experimental tanks (3 per biomass treatment) were used and randomly assigned one of the following biomass treatments: control = 0...
Drivers, characteristics, and impacts of streamflow drought across the Delaware River Basin Drivers, characteristics, and impacts of streamflow drought across the Delaware River Basin
This data release contains supporting input data tables and results from analysis to identify and interpret clusters of drought events with similar meteorological and hydrological characteristics in the Delaware River Basin. Input data consists of hydrologic variables from the National Hydrologic Model Infrastructure with Precipitation-Runoff Modeling System, version 1.1 (NHM-PRMS v1.1)
Data for Factors affecting Benthic Macroinvertebrate Health in the City of Roanoke Virginia, 2020 – 2023 Data for Factors affecting Benthic Macroinvertebrate Health in the City of Roanoke Virginia, 2020 – 2023
The United States Geological Survey Virginia and West Virginia Water Science Center (USGS VA-WV-WSC) and City of Roanoke, Virginia assembled this data release to support a report that analyzed factors affecting benthic macroinvertebrate health in the City of Roanoke, Virgina between calendar years 2020 and 2023. The benthic macroinvertebrate and stream habitat sampling and surveying were...
