Upper Colorado River Basin Accumulated Wastewater Ratios and PFAS Model Predictions (ver. 2.0, August 2025) Upper Colorado River Basin Accumulated Wastewater Ratios and PFAS Model Predictions (ver. 2.0, August 2025)
A wastewater reuse model was applied to the Upper Colorado River basin to assess the (1) percent of accumulated wastewater (ACCWW%) from municipal and industrial wastewater treatment plants (WWTPs) in each initialized (that is, has an assigned hydrosequence number for flow-routing) National Hydrography Dataset Version 2.1 (NHDPlus V2.1) stream segment; and (2) predicted environmental
Performance maps, weights, and associated data sets for Version 2.0 of the OpenET evapotranspiration models for the conterminous U.S. Performance maps, weights, and associated data sets for Version 2.0 of the OpenET evapotranspiration models for the conterminous U.S.
This data release provides maps of estimated performance metrics for the remotely sensed evapotranspiration (ET) models within the OpenET ensemble, at the scale of the conterminous U.S. (CONUS). It also provides relative weight maps for each of the ensemble models that can be used to produce performance-weighted ensemble estimates. These maps are provided at a 4 kilometer spatial...
Survey Data for Siskiyou Mountains Salamanders (Plethodon stormi) and Scott Bar Salamanders (P. asupak) in Siskiyou County, California, 2023-2024 Survey Data for Siskiyou Mountains Salamanders (Plethodon stormi) and Scott Bar Salamanders (P. asupak) in Siskiyou County, California, 2023-2024
These data contain information about the sites, visits, and transects surveyed for Siskiyou Mountains salamanders (Plethodon stormi) and Scott Bar salamanders (P. asupak) in Siskiyou County, California, 2023-2024. The survey sites were near locations of recent (since 2005) historical occurrence of the salamanders and were designed to separate occurrence, availability on the surface, and...
Nearshore Electrical Resistivity Tomography (ERT) profile data, Ofu, American Samoa, February 2020 Nearshore Electrical Resistivity Tomography (ERT) profile data, Ofu, American Samoa, February 2020
Along-shore surface-based 2D electrical resistivity tomography (ERT) surveys were collected in the nearshore region of Ofu, American Samoa.
Nearshore seawater-column measurements of coastal groundwater discharge, Ofu, American Samoa, February 2020 Nearshore seawater-column measurements of coastal groundwater discharge, Ofu, American Samoa, February 2020
In-situ nearshore seawater measurements of dissolved radon and water level were used to determine the advection rate of groundwater onto the fringing reef off Ofu, American Samoa.
2023 Environmental DNA (eDNA) Baseline to Monitor Intertidal Biodiversity in Waters Adjacent to Mixed Coarse Substrate Habitats Across the Boston Harbor Islands 2023 Environmental DNA (eDNA) Baseline to Monitor Intertidal Biodiversity in Waters Adjacent to Mixed Coarse Substrate Habitats Across the Boston Harbor Islands
This data set contains environmental DNA (eDNA) data enumerating the presence of intertidal marine vertebrates, invertebrates, and macro algae collected across 5 islands with 10 sites in the Boston Harbor in 2023. This data was collected using water samples collected in association with other intertidal biodiversity monitoring protocols developed specifically for the mixed coarse...
