PFAS accumulation and effects in juvenile ospreys (Pandion haliaetus) from Chesapeake and Delaware Bays PFAS accumulation and effects in juvenile ospreys (Pandion haliaetus) from Chesapeake and Delaware Bays
Per- and polyfluoroalkyl substances (PFAS) are a class of ubiquitous, environmentally persistent compounds that pose a threat to human and wildlife health. Ospreys (Pandion halieatus) are a model avian species with a documented history of serving as effective bioindicators of contamination. Our study aims to provide a more thorough understanding of PFAS presence in the Chesapeake and...
Topographic data, aerial imagery, and GPS data collected during uncrewed aircraft system (UAS) operations at Lower Darby Creek, Darby Township, Pennsylvania, March to August 2024 Topographic data, aerial imagery, and GPS data collected during uncrewed aircraft system (UAS) operations at Lower Darby Creek, Darby Township, Pennsylvania, March to August 2024
The U.S. Geological Survey deployed small uncrewed aircraft systems (sUAS) to collect aerial remote sensing data across sites within the Lower Darby Creek Superfund Site and the adjacent John Heinz National Wildlife Refuge (JHNWR) ~5 miles outside of Philadelphia, PA in March and August of 2024. March datasets include aerial images from natural color (RGB) and thermal infra-red (TIR)...
Hawaiian Islands High-Resolution Topographical and Ecological Raster Datasets for Conservation Planning 2025 Hawaiian Islands High-Resolution Topographical and Ecological Raster Datasets for Conservation Planning 2025
This data release comprises a collection of high-resolution environmental raster data for the Hawaiian Islands, developed to support conservation planning and ecological research. The collection includes both 30-meter and 10-meter resolution GeoTIFFs with topographical variables (elevation, aspect, slope, hillshade, and geomorphon landform classification), as well as complementary...
Watershed Data Management (WDM) Database (WBDR23.WDM) for West Branch DuPage River Streamflow Simulation, DuPage County, Illinois, January 1, 2007, through September 30, 2023 Watershed Data Management (WDM) Database (WBDR23.WDM) for West Branch DuPage River Streamflow Simulation, DuPage County, Illinois, January 1, 2007, through September 30, 2023
This data release (DR) is the update of the U.S. Geological Survey (USGS) - ScienceBase (SB) DR Bera (2024b), with the processed data for the period October 1, 2022, through September 30, 2023. This SB DR describes the watershed data management (WDM) database WBDR23.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and...
Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024 Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024
This data set contains Lake Trout (Salvelinus namaycush) egg density estimates obtained from suction sampling across five locations in Lake Ontario. These data were collected in October-November 2020 and November-December 2024 as part of an effort to identify Lake Trout spawning locations and habitat preference in Lake Ontario. Additional information on habitat characteristics at each...
Potential for microbially mediated nitrogen transformations in benthic algae, sediment, and overlying water in the Great Lakes, 2022 Potential for microbially mediated nitrogen transformations in benthic algae, sediment, and overlying water in the Great Lakes, 2022
This dataset is associated with an examination of environmental DNA (eDNA) obtained from freshwater matrices (i.e. benthic algae, sediment, and near bottom water) collected by scuba divers from previously established transects located along the U.S. shoreline of Lakes: Michigan, Huron, Erie, and Ontario. 16S rRNA gene amplicon sequencing (i.e., targeting bacterial communities) and high...
