WRTDS-K nutrient and sediment loads at Illinois EPA Ambient Water Quality Monitoring Network sites, from WY 1978 through 2020 WRTDS-K nutrient and sediment loads at Illinois EPA Ambient Water Quality Monitoring Network sites, from WY 1978 through 2020
This data release contains estimates of annual nitrate, suspended sediment, phosphorus, and chloride loads and uncertainty from sites in the Illinois Environmental Protection Agency (Illinois EPA) Ambient Water Quality Monitoring Network. The loads were estimated using Weighted Regressions on Time, Discharge, and Season with Kalman filtering (WRTDS-K) and existing discrete water-quality...
Estimated tree mortality, basal area, climate, and drought conditions for ponderosa pine in forest inventory plots across the western U.S. Estimated tree mortality, basal area, climate, and drought conditions for ponderosa pine in forest inventory plots across the western U.S.
These data consist of environmental covariates and estimated plot-level mortality of ponderosa pine trees. Environmental covariates include growing season temperature and soil moisture, and values are summarized into long-term mean conditions, and anomalies observed between forest inventory sampling events for each plot. Data also include plot locations (with uncertainty introduced by...

Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA (ver. 2, December 2023) Topographic and bathymetric data, sediment samples, structure from motion imagery, and reference mark data collected at Marconi Beach, Wellfleet in winter 2021, U.S Geological Survey Field Activity 2021-022-FA (ver. 2, December 2023)
The data in this publication map the beach and nearshore environment at Marconi Beach in Wellfleet, MA and provide regional context for the 2021 CoastCam installation that looks out at the coast shared by beachgoers, shorebirds, seals, and sharks. These data were collected as part of field activity 2021-022-FA and a collaboration with the National Park Service at Cape Cod National...
Illinois River: Emiquon and surrounding area aerial imagery Illinois River: Emiquon and surrounding area aerial imagery
Located in floodplain of the Illinois River near Havana, IL, Emiquon is one of the largest floodplain restoration projects in the Midwest. The Nature Conservancy (TNC) and U.S. Fish and Wildlife Service (FWS) manage a TNC preserve and FWS Naitonal Wildlife Refuge in this area. In 2012, the Emiquon National Wildlife Refuge was designated a "Ramsar Wetland of International Importance."
