Serum samples were collected from an American Kestrel colony at the U.S. Geological Survey (USGS) Eastern Ecological Science Center and analyzed for per- and polyfluoroalkyl substances (PFAS). The sampling effort was undertaken as part of a Strategic Environmental Research and Development Program (SERDP) funded project (ER22-3388) to study the exposure effect of PFAS on immunomodulation...

This Data Release contains four child items that represent sequential data processing and modeling steps. {Child Item 1} Data Preparation contains data inputs and processing steps for select sites in the Delaware and Illinois River Basins (DRB/IRB). This child item includes five sub folders: site info, streamflow and turbidity time-series, climatological information, basin shape...

This data release consists of flood hazard maps from compound coastal hazards--specifically sea-level rise (SLR), projected coastal storms, and streamflow. Products include projected flood depths, flood extents including uncertainties, water elevations, velocity hazards, and flood duration. These are generated using a suite of numerical models driven by outputs from Global Climate Models...

This study investigates the feeding and trophic ecology of invasive Blue Catfish (Ictalurus furcatus) in the Nanticoke River watershed on the Chesapeake Bay’s Eastern Shore (Maryland, U.S.A). From a total of 1,032 stomach samples collected, a subset of 88 was analyzed using 18S and COI metabarcoding primers to enhance taxonomic resolution of prey items. USGS-generated genetic reference...

This data release provides spatial digital data for factors that influence pluvial flood hazard potential, including closed depressions, curve number, drainage networks, topographic slope, average annual rainfall, 1-hr and 24-hour 100-year return period rainfall accumulation, and locations of recorded floods. In addition, these flood influencing factors are summarized to a common 900...

This legacy dataset includes digitized ground temperatures from four borehole sites in Utqiagvik, Alaska. The data were measured by scientists from the Naval Arctic Research Laboratory (NARL) on a weekly to biweekly frequency spanning 1950 to 1961. The datasets include ground temperatures at approximately 15-24 depth increments down to 60-110 ft (28-33 m) (with higher measurement...

Monthly surface water samples were collected at sites in the Lake Pontchartrain estuary to assess the phytoplankton biomass and composition using algal pigment analysis. A total of 27 algal pigments including chlorophyll a and accessory pigments were evaluated from each of the water samples.

Infinity water level recorders were installed in 2004 to monitor hydrologic conditions in five freshwater forested wetlands in Louisiana: Bayou Chevreuil, Bayou Teche National Wildlife Refuge, Mandalay National Wildlife Refuge, Jean Lafitte National and Historical Park, and Treasure Island. Hourly measurements were collected continuously on a 24- hour basis through April 2022, producing...

This software release contains the R code to jointly run an integrated population model (IPM) and Bayesian population viability analysis (BPVA) for the Cape Sable Seaside Sparrow (CSSS; Ammospiza maritima mirabilis). The CSSS is a federally endangered bird endemic to a small part of the Everglades in southern Florida, USA. The IPM-BPVA synthesizes thirty years (1992-2021) of range-wide...

We monitored breeding birds at Whiskey Island, Louisiana between March through July from 2015 to 2020. We surveyed all available habitat by foot, using high-powered spotting scopes and binoculars to search for and identify nesting birds. We documented species, abundance, habitat, location, and breeding behavior for each bird that we observed to be breeding. We modeled the counts of...

This data release contains the boundaries of assessment units and input data for the assessment of undiscovered oil and gas resources in the Santa Maria Basin Province, California. The assessment unit is the fundamental unit used in the National Assessment Project for the assessment of undiscovered oil and gas resources. The assessment unit is defined within the context of the higher...
