Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Native freshwater mussel density and population estimates from a systematic survey in the Rappahannock River, Virginia, in 2024 Native freshwater mussel density and population estimates from a systematic survey in the Rappahannock River, Virginia, in 2024
Native freshwater mussels are a substantial resource of concern to resource managers because of their contribution to aquatic ecosystems, First Foods status for Native American tribes, and general imperilment. As such, resource managers in the USFWS Lower Great Lakes Fish and Wildlife Conservation Office partnered with USGS to characterize the native freshwater mussel assemblage in the...
Estimates of Elk Aggregation Metrics Calculated Across Varying Sample Sizes from Two Herds in Western Wyoming, USA Estimates of Elk Aggregation Metrics Calculated Across Varying Sample Sizes from Two Herds in Western Wyoming, USA
This data is a compilation of elk aggregation metrics (inter-animal distance, proximity rate, and kernel density contour area) calculated using GPS collar data from elk belonging to the Jackson and West Green River herds in western Wyoming, USA. The data represents two seasonal time periods (high- and low-density) for animals from each herd. Time periods of inference vary by herd and...
2020 Level 2 Aquatic Areas - Upper Mississippi River System 2020 Level 2 Aquatic Areas - Upper Mississippi River System
The U.S. Army Corps of Engineers' Upper Mississippi River Restoration (UMRR) program, through its Long Term Resource Monitoring (LTRM) element, collected aerial imagery of the systemic Upper Mississippi River System (UMRS) during the summer of 2020. A Land Cover/Land Use (LCU) spatial database was developed based on the 2020 aerial imagery, which adds a fourth systemic-wide database to...
Antimycin A cytotoxicity to rainbow trout gill cell line (RTgill-W1): Exploring a new screening approach for prioritizing pesticide candidates Antimycin A cytotoxicity to rainbow trout gill cell line (RTgill-W1): Exploring a new screening approach for prioritizing pesticide candidates
This dataset describes in vitro Rainbow trout (Oncorhynchus mykiss) RTgill-W1gill cell cytotoxicity assay fluorescence data used to estimate the effective concentration to cause 50% viability (EC50) of cells following antimycin A (complex and individual homologs) exposure. Antimycin A dosing stocks were analytically verified using high-performance liquid chromatography with tandem triple
MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts MODPATH Model Used to Evaluate Flowpaths from Two Contaminant Plume Source Areas near Joint Base Cape Cod, Western Cape Cod, Massachusetts
The U.S. Geological Survey (USGS) used an existing groundwater flow model to determine steady-state groundwater flowpaths from two contaminant plume source areas by using a particle tracking post-processing model (MODPATH; Pollock, 2012) as part of an assessment of potential contaminant discharge at the coast in Bourne, Massachusetts. The extents of the source areas, originating from two...
Data supporting "Detecting bumble bees in the wild using environmental DNA: development and validation of a qPCR assay for the endangered Franklin's bumble bee (Bombus franklini)" Data supporting "Detecting bumble bees in the wild using environmental DNA: development and validation of a qPCR assay for the endangered Franklin's bumble bee (Bombus franklini)"
This dataset includes quantitative polymerase chain reaction (qPCR) data for an in vitro test of the Bombus franklini eDNA assay using target and nontarget DNA extract, qPCR data for a plate used to calculate the limits of detection and quantification of the assay based on serial 10-fold dilutions of B. franklini gBlock, qPCR data for an in situ test of the assay using flower samples...
