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.

CMIP6-LOCA2 spatial summaries of HU8 and HU10 watershed boundaries from 1950-2100 for the Contiguous United States CMIP6-LOCA2 spatial summaries of HU8 and HU10 watershed boundaries from 1950-2100 for the Contiguous United States
Three different CMIP6-LOCA2 based climate projection data sets are spatially averaged over the Watershed Boundary Dataset (WBD) using HU8 and HU10 hydrologic units for the contiguous United States to provide time series for analysis. The primary data set is the statistically downscaled CMIP6-LOCA2 (Localized Constructed Analogs, v20220519 version, Pierce et al. 2023), which includes...
Grass Carp Movement and Removal Effort Data from the Sandusky River, Lake Erie, Ohio, USA from 2022 to 2023 Grass Carp Movement and Removal Effort Data from the Sandusky River, Lake Erie, Ohio, USA from 2022 to 2023
Data include grass carp position and sampling data from 2022 to 2023. We used grass carp that were implanted with acoustic transmitters. The position data was generated in Fathom Position from receivers that composed several VEMCO Positioning Systems (VPS). We also queried the Great Lakes Acoustic Telemetry Observation Network (GLATOS) to obtain non-VPS position detections from receivers...
Historical and future simulated streamflow and sediment loads from Clear Lake tributaries in California Historical and future simulated streamflow and sediment loads from Clear Lake tributaries in California
This dataset includes simulated streamflow and sediment discharge for major tributaries contributing to Clear Lake, California. Historical hourly streamflow and sediment for each tributary location were outputs from an Hydrological Simulation Program - FORTRAN (HSPF) model. The historical data is available at an hourly time step from October 1980 to March 2024. The future time series...
Select Mineral Abundancy Data from Alaska Placer and Pan Concentrate Samples Reanalyzed from 2020-2023 Select Mineral Abundancy Data from Alaska Placer and Pan Concentrate Samples Reanalyzed from 2020-2023
Samples from the Alaska Placer Concentrate Collection (APCC) were retrieved from the USGS National Geochemical Sample Archives and submitted for mineralogical analysis at the Colorado School of Mines. The APPC contains samples from placer mining operations throughout Alaska. The original collection contained approximately 5,000 samples that were collected by U.S. Geological Survey...
Bibliography of U.S. Geological Survey Contributions to Carbon and Greenhouse Gas Science Bibliography of U.S. Geological Survey Contributions to Carbon and Greenhouse Gas Science
This data release contains a bibliography of U.S. Geological Survey publications on carbon and greenhouse gas research. Publications between 2014 and 2024 were identified using search terms such as: carbon, greenhouse gas, methane, nitrous oxide, emission, sequestration, and primary productivity. Publications were primarily sourced from the USGS Publications Warehouse (https://pubs.usgs...
