Bathymetric data for Selected Resacas in the Brownsville, Texas area, September 2021 through April 2023 Bathymetric data for Selected Resacas in the Brownsville, Texas area, September 2021 through April 2023
The U.S. Geological Survey, in cooperation with the City of Brownsville, Texas, collected bathymetric data for selected resacas (former distributary channels and oxbow lakes of the Rio Grande that are now cut off from the river) in the Brownsville, Texas area during September 2021 through April 2023. Bathymetric survey points were collected using real-time network Global Navigation...
USGS 3D Hydrography Program (3DHP) Data Collaboration Announcement Projects from Fiscal Year 2024 to Present (ver. 2.0, December 2025) USGS 3D Hydrography Program (3DHP) Data Collaboration Announcement Projects from Fiscal Year 2024 to Present (ver. 2.0, December 2025)
These data depicts 3D Hydrography Program (3DHP) Data Collaboration Announcement (DCA) hydrography data acquisition projects from federal fiscal year (FY) 2024 to present. The DCA provides a mechanism for partnering with the USGS and other Federal agencies to acquire high-quality hydrography data to provide the Nation with high-resolution hydrographic products to support a broad array of
Chronic wasting disease (CWD) survey by hunters in Massachusetts in early 2023. Chronic wasting disease (CWD) survey by hunters in Massachusetts in early 2023.
We implemented an online survey questionnaire for adult Massachusetts licensed hunters in December 2022-February 2023 using the Qualtrics survey platform (Qualtrics, Provo, UT). The online survey covers a number of topics related to chronic wasting disease (CWD) such as knowledge, risk perception, management acceptability, hunting behavior, channel use, and trust in different sources. Of...
Long-term monotonic trends in aquifer and regional groundwater metrics in the United States through 2020 Long-term monotonic trends in aquifer and regional groundwater metrics in the United States through 2020
The U.S. Geological Survey (USGS) Water Resources Mission Area (WMA) is working to address a need to understand where the Nation is experiencing water shortages or surpluses relative to the demand by delivering routine assessments of water supply and demand. A key part of these national assessments is identifying long-term trends in water availability, including groundwater and surface...

This vector data set represents the evapotranspiration (ET) discharge quantification area polygon in the lower Walker River basin.
Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025) Particle size distribution of MIS 5a aeolianites across windward islands of the Bahamas (Great Abaco, Eleuthera, San Salvador, and Long Island) (ver. 1.1, May 2025)
Recent Quaternary carbonate island sediment preservation along low-latitude coastal regions, such as in the Bahamas, contain sediment sourced from adjacent marine environments during interglacial intervals. During these interglacial intervals, denoted by odd-numbered Marine Isotope Stages (e.g., MIS 1, 3, 5), sea levels are at a highstand relative to glacial periods (e.g., MIS 2, 4, 6)...
