Environmental Sampling of Per- and Polyfluoroalkyl Substances in the Middle Chickahominy River Watershed, Virginia, 2021-2022 (ver. 2.0, September 2023) Environmental Sampling of Per- and Polyfluoroalkyl Substances in the Middle Chickahominy River Watershed, Virginia, 2021-2022 (ver. 2.0, September 2023)
These data were collected to understand the occurrence of Per- and Polyfluoroalkyl Substances (PFAS) in the middle Chickahominy River watershed. Specifically, this effort was initiated to: 1. Determine concentrations of PFAS in surface water at select locations in the middle Chickahominy River watershed; 2. Determine concentrations of PFAS in edible portions of fish at select locations...
Common loon migration and winter data: telemetry locations and archival geolocator tag location (ver 2.0, October 2022) Common loon migration and winter data: telemetry locations and archival geolocator tag location (ver 2.0, October 2022)
The data details common loon locations based on archival geolocator tag information, characteristics of common loon dives during wintering, and common loon locations based on telemetry data. Satellite transmitters (Model PTT-100, Microwave Telemetry, Inc) were implanted in 31 adult male (marked during July 2010 and July 2011) and 27 juvenile (marked during August 2014 and August 2015)...
Genetically informed seed transfer zones for Astragalus lonchocarpus, Cleome serrulata, and Heliomeris multiflora across the Colorado Plateau and adjacent regions Genetically informed seed transfer zones for Astragalus lonchocarpus, Cleome serrulata, and Heliomeris multiflora across the Colorado Plateau and adjacent regions
These data were compiled to provide seed transfer and native plant materials development guidance to managers and practitioners across the Colorado Plateau and in adjacent regions. This data release contains empirical seed transfer zones derived from molecular genetic data for Cleome serrulata (syn. Peritoma serrulata), Heliomeris multiflora, and Astragalus lonchocarpus. These species...
Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2021 Nitrogen, phosphorus, and suspended-sediment loads and trends measured at the Chesapeake Bay River Input Monitoring stations: Water years 1985-2021
Nitrogen, phosphorus, and suspended-sediment loads, and changes in loads, in major rivers across the Chesapeake Bay watershed have been calculated using monitoring data from the Chesapeake Bay River Input Monitoring (RIM) Network stations for the period 1985 through 2021. Nutrient and suspended-sediment loads and changes in loads were determined by applying a weighted regression approach...
RestoreNet subplot data for 21 sites within major dryland ecoregions throughout the southwestern United States, 2018 - 2021 RestoreNet subplot data for 21 sites within major dryland ecoregions throughout the southwestern United States, 2018 - 2021
These data were compiled for a networked field-trial restoration experiment (RestoreNet) that spans the southwestern US, including 21 distributed field sites. The objective of our study was to understand the environmental factors and restoration practices (including seed mixes and soil manipulation) that increase plant establishment and survival to ultimate improve restoration outcomes...
Webb and Rosenberry, 2020, MODFLOW 2005 and MODPATH 5 model data sets used to evaluate seepage-meter efficiency in high-permeability settings Webb and Rosenberry, 2020, MODFLOW 2005 and MODPATH 5 model data sets used to evaluate seepage-meter efficiency in high-permeability settings
A three-dimensional finite-difference model, MODFLOW-2005 (version 1.12.00), was developed to better understand how Seepage Meter efficiency changes when installed in sediments with wide range of conductivities. The hypothesis is that coarser sediments will allow a greater portion of upward-flow to flow around the meter instead of through it. The hypothetical model simulates upward flow...
