Global Daily Grass Reference Evapotranspiration (ETo) Climatology (1981–2010) Derived from Integrated Multi‑Source Data Global Daily Grass Reference Evapotranspiration (ETo) Climatology (1981–2010) Derived from Integrated Multi‑Source Data
This dataset provides a globally consistent daily climatology of grass reference evapotranspiration (ETo, units in millimeter) for the 1981–2010 climatological period. The product integrates multiple sources to improve spatial completeness and regional accuracy, including TerraClimate monthly potential evapotranspiration (PET) fields, the Australian Bureau of Meteorology...
Trends in Nutrient and Other Water Quality Constituent Loads to the Gulf of America from the Mississippi and Atchafalaya Rivers, 1980–2025 (ver. 3.0, May 2026) Trends in Nutrient and Other Water Quality Constituent Loads to the Gulf of America from the Mississippi and Atchafalaya Rivers, 1980–2025 (ver. 3.0, May 2026)
The National Water Quality Network (NWQN) for Rivers and Streams includes 105 sites monitored by the U.S. Geological Survey (USGS) National Water Quality Program (https://www.usgs.gov/mission-areas/water-resources/science/usgs-national-water-quality-network). This data release provides streamflow, nutrient, and sediment data collected and analyzed by USGS for one Mississippi River site...
Scale Specific Sinuosity metrics and associated derived and modeled Manning’s n values for the global SWOT River Database (SWORD), v17b Scale Specific Sinuosity metrics and associated derived and modeled Manning’s n values for the global SWOT River Database (SWORD), v17b
Scale Specific Sinuosity (S3) attributes are generated for the global SWOT River Database (SWORD) stream reaches greater than 150 meters in length. The S3 and SWORD reach attributes are used in a Random Forest model, trained on 745 gage sites on SWORD measured reaches in North America with available USGS ADCP data. The model is used to predict a baseline Manning’s n resistance...
Decadal Trends in Streamflow and Stream Temperature across the Contiguous United States, Alaska, Hawaii, and Puerto Rico (1980–2020): Input Data and R Code Decadal Trends in Streamflow and Stream Temperature across the Contiguous United States, Alaska, Hawaii, and Puerto Rico (1980–2020): Input Data and R Code
This data release contains the input data and R scripts to compile streamflow and stream temperature trend outputs (Hecht and others, 2024; Johnson, 2025), calculate Mann-Kendall and Theil-Sen slope trends for driver datasets (Konrad, 2020; PRISM Climate Group, 2014; USGS, 2024), and determine trend likelihood categories and associated driver correlations. The dataset includes 7,655...
Inventory of Shorebirds and other Bird Species in Western Alaska including the Seward Peninsula, Nulato Hills, Unalakleet, and Cape Krusenstern National Monument, 1988-2012 Inventory of Shorebirds and other Bird Species in Western Alaska including the Seward Peninsula, Nulato Hills, Unalakleet, and Cape Krusenstern National Monument, 1988-2012
This data release contains tabular data and photographs from avian surveys of shorebird, predator birds, and other bird species in western Alaska between 1988 and 2012. The data package includes seven tables: 1) characteristics of bird survey sites, 2) habitat classification at survey sites, 3) detections of all birds at survey sites, 4) detections and behaviors of shorebirds and...
Lower Cook Inlet Fish and Invertebrate Community Composition, Distribution, and Density Lower Cook Inlet Fish and Invertebrate Community Composition, Distribution, and Density
This data package includes seven tables with data about the composition, distribution, relative abundance, seasonal availability, energy density, morphometrics, taxonomy, and stable isotope values of benthic fish and invertebrates, as well as oceanographic data within the proposed oil and gas lease sale area in lower Cook Inlet, Alaska.
