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.

Shotgun sequencing of multiple families of Polychaeta from U.S. Atlantic margin seeps and eDNA metabarcoding sequences of benthic community from Cascadia margin seeps using 18S marker, 2018–2019 Shotgun sequencing of multiple families of Polychaeta from U.S. Atlantic margin seeps and eDNA metabarcoding sequences of benthic community from Cascadia margin seeps using 18S marker, 2018–2019
Reported here are the geographic sampling information associated with the raw shotgun sequencing data of multiple families of Polychaeta samples collected from cold seep sites off the U.S. Atlantic margin as well as raw 18S amplicon sequencing data from sediment eDNA collected from Astoria Canyon seeps, located on the Cascadia margin, northeastern Pacific Ocean. Also included are GenBank...
Louisiana Barrier Island Comprehensive Monitoring Program – 2021 habitat map, Modern Delta Region Louisiana Barrier Island Comprehensive Monitoring Program – 2021 habitat map, Modern Delta Region
The Barrier Island Comprehensive Monitoring (BICM) program was developed by Louisiana’s Coastal Protection and Restoration Authority (CPRA) and is implemented as a component of the System Wide Assessment and Monitoring Program (SWAMP). The program uses both historical data and contemporary data collections to assess and monitor changes in the aerial and subaqueous extent of islands...
A Conodont Biostratigraphic and Color Alteration Index Dataset for New England: Maine, Vermont, Massachusetts, and parts of eastern New York, USA A Conodont Biostratigraphic and Color Alteration Index Dataset for New England: Maine, Vermont, Massachusetts, and parts of eastern New York, USA
For decades, researchers have recognized the functionality of using conodont elements in biostratigraphic investigations. A growing need now exists, however, for a digital dataset of fossil data. The New England conodont dataset is the region's first publicly accessible digital collection of previously published U.S. Geological Survey (USGS) conodont paleontological data and Color...
Index Velocity Rating Example Datasets Index Velocity Rating Example Datasets
These data are a compilation of example index velocity ratings used at USGS streamgaging stations. Each directory contains seven comma-delimited files consisting of a read me, the hydrographer developed rating, a table of discharge measurements used to develop the velocity rating, a mixture model analysis, statistically recommended rating, and the variance covariance matrix for both the

This data release presents a national cross-section (XS) database (NXSDB) of bathymetric cross-sections collected during water year (WY) 2022 (October 1, 2021, to September 30, 2022). The WY 2022 NXSDB has been approved by the U.S. Geological Survey (USGS) for publication and supersedes the provisional versions. The data were collected by hydrographers during routine site visits to...
