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.

Hawaiian Islands High-Resolution Topographical and Ecological Raster Datasets for Conservation Planning 2025 Hawaiian Islands High-Resolution Topographical and Ecological Raster Datasets for Conservation Planning 2025
This data release comprises a collection of high-resolution environmental raster data for the Hawaiian Islands, developed to support conservation planning and ecological research. The collection includes both 30-meter and 10-meter resolution GeoTIFFs with topographical variables (elevation, aspect, slope, hillshade, and geomorphon landform classification), as well as complementary...
Watershed Data Management (WDM) Database (WBDR23.WDM) for West Branch DuPage River Streamflow Simulation, DuPage County, Illinois, January 1, 2007, through September 30, 2023 Watershed Data Management (WDM) Database (WBDR23.WDM) for West Branch DuPage River Streamflow Simulation, DuPage County, Illinois, January 1, 2007, through September 30, 2023
This data release (DR) is the update of the U.S. Geological Survey (USGS) - ScienceBase (SB) DR Bera (2024b), with the processed data for the period October 1, 2022, through September 30, 2023. This SB DR describes the watershed data management (WDM) database WBDR23.WDM. The precipitation data are collected from a tipping-bucket rain-gage network and the hydrologic data (stage and...
Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024 Lake trout (Salvelinus namaycush) egg density estimates in Lake Ontario from egg pumping, 2020, 2024
This data set contains Lake Trout (Salvelinus namaycush) egg density estimates obtained from suction sampling across five locations in Lake Ontario. These data were collected in October-November 2020 and November-December 2024 as part of an effort to identify Lake Trout spawning locations and habitat preference in Lake Ontario. Additional information on habitat characteristics at each...
Potential for microbially mediated nitrogen transformations in benthic algae, sediment, and overlying water in the Great Lakes, 2022 Potential for microbially mediated nitrogen transformations in benthic algae, sediment, and overlying water in the Great Lakes, 2022
This dataset is associated with an examination of environmental DNA (eDNA) obtained from freshwater matrices (i.e. benthic algae, sediment, and near bottom water) collected by scuba divers from previously established transects located along the U.S. shoreline of Lakes: Michigan, Huron, Erie, and Ontario. 16S rRNA gene amplicon sequencing (i.e., targeting bacterial communities) and high...
Benthic Algal Community Composition in the Laurentian Great Lakes (2024) Benthic Algal Community Composition in the Laurentian Great Lakes (2024)
This data set includes information on benthic algae community composition collected during the growing season of 2024 at stations located along the U.S. shoreline of Lakes Michigan, Huron, Erie, and Ontario. Benthic algal community observations were taken by scuba divers in the field and by personnel in the lab during sample processing, including detailed microscopic examination of...
Data Describing Effects of Bison (Bison bison) Herbivory on Herbaceous Production and Nitrogen Yield throughout Grand Canyon Grasslands from 2021 to 2022 Data Describing Effects of Bison (Bison bison) Herbivory on Herbaceous Production and Nitrogen Yield throughout Grand Canyon Grasslands from 2021 to 2022
This dataset includes three datasets collected in 2021 and 2022 to assess the potential effects of bison (Bison bison) herbivory and climate on grassland functional properties throughout semi-arid meadows in Grand Canyon National Park and Kaibab National Forest of northern Arizona. Bison herbivory offtake (utilization) and aboveground herbaceous production are demonstrated in the...
