Twelve-digit hydrologic unit total flow and snowmelt from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System, 1980-2016 Twelve-digit hydrologic unit total flow and snowmelt from the National Hydrologic Model Infrastructure with the Precipitation-Runoff Modeling System, 1980-2016
This dataset is part of the National Water Census ongoing development of best estimates of daily historical water budgets for over 100,000 hydrologic units across the United States. In this release, estimates of total flow and snowmelt for each hydrologic unit are added to the already released estimates of actual evapotranspiration, snowpack water-equivalent storage, soil moisture...
Contemporary fire history metrics for the conterminous United States (1984-2025)(ver. 5.0, April 2026) Contemporary fire history metrics for the conterminous United States (1984-2025)(ver. 5.0, April 2026)
Fire history metrics enable rapidly increasing amounts of burned area data to be collapsed into a handful of data layers that can be used efficiently by diverse stakeholders. In this effort, the U.S. Geological Survey's Landsat Burned Area product was used to identify burned area across CONUS over a 41-year period (1984-2024). The Landsat BA product was consolidated into a suite of...
Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity O-1-99-SC Reprocessed multichannel seismic reflection data acquired offshore Southern California during USGS field activity O-1-99-SC
Multichannel seismic (MCS) data were collected by the U.S. Geological Survey (USGS) in June of 1999 in the coastal zone and continental shelf between Los Angeles and San Diego, offshore California (USGS field activity O-1-99-SC). In 2021 these data were reprocessed to improve accuracy and resolvability of geologic structures and fault systems of California's continental margin.
Macroinvertebrate community and sediment toxicity data from the Eighteenmile Creek Area of Concern, New York, 2021 Macroinvertebrate community and sediment toxicity data from the Eighteenmile Creek Area of Concern, New York, 2021
A data release containing information on benthic macroinvertebrate communities and sediment toxicity in the Eighteenmile Creek Area of Concern and a nearby reference area at Oak Orchard Creek. Bed sediments were collected during summer 2021 at 8 sites on Eighteenmile Creek and at 6 sites on Oak Orchard Creek using a petite Ponar dredge for macroinvertebrate identification and sediment...
Sampling Data for Eelgrass (Zostera marina) in Norma Bay, Izembek Lagoon, Alaska, 1987 Sampling Data for Eelgrass (Zostera marina) in Norma Bay, Izembek Lagoon, Alaska, 1987
These data are related to surveys of eelgrass beds in Norma Bay, Izembek Lagoon, Alaska. The table provides eelgrass shoot lengths and density measurements from sampling in September 1987.
Fisheries-dependent data for Cisco in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron between 1929 and 1970 Fisheries-dependent data for Cisco in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron between 1929 and 1970
This data release presents part of historical fisheries-dependent data for Cisco (Coregonus artedi) in Green Bay of Lake Michigan and Saginaw Bay of Lake Huron collected by scientists from U.S. Geological Survey's Great Lakes Science Center, including three tables for monthly Cisco-catch and fishing-effort data and two tables for biological data of Cisco individuals. The monthly Cisco...
