All Data

Data files contain the simulated mean daily environmental conditions in Lake Michigan for historical (2005, 2006, 2010, 2014, 2015, and 2016) and future (2040-2049, 2090-2099) years. Simulations were generated by integrating a series of climatic, hydrodynamic, and biological models. Each year's dataset predicts water temperature, photosynthetically active radiation, and phytoplankton...

The U.S. Geological Survey (USGS) Oregon Water Science and Forest and Rangeland Ecosystem Science Centers have developed a spatial database of the stream network in the Willamette River Basin classified by degree of obstruction to fish passage. This effort was funded by the USGS Ecological Flows program in cooperation with the Integrated Water Availability Assessments in the Willamette...

This report and associated dataset, contains subsurface geologic information collected in the Sacramento-San Joaquin Valley. The primary data includes X, Y, Z locations of stratigraphic horizons and, to a much lesser extent, geologic structures where penetrated by oil and gas wells in the subsurface as recorded in well logs and well records. Selected oil and gas wells are not only...

Hydraulic models of the Siletz River, Oregon, were developed using the U.S. Army Corps of Engineers Hydraulic Engineering Center River Analysis System (HEC-RAS; version 6.5). A one-dimensional (1D) steady-flow model was developed from Moonshine Park to the City of Siletz, Oregon (river kilometer [Rkm] 87.2 to 68.5). Results from the 1D model provided insights into longitudinal patterns...

Sedimentary charcoal particle data and 14C age control measurements derived from a core recovered from Paixban, a wetland/lake in northern Guatemala in 2003

We used Wilderlab eDNA kits to collect eDNA samples in a creek colloquially known as Cañada del Puerto Creek (Hydrologic Unit Code 12 number 180600140201) on Santa Cruz Island, California, in May 2025. Samples were sent to Wilderlab for metabarcoding analysis using their comprehensive panel of assays to amplify DNA from a variety of taxa, including vertebrates (fish, mammals, reptiles...

Planktic foraminifera are single-celled organisms playing a crucial role in marine food webs by cycling nutrients within ecosystems. They are heterotrophic protists feeding on phytoplankton, the primary producers in the ocean. In turn, planktic foraminifera serve as a food source for a range of marine animals including fish, crustaceans, other zooplankton, and larger predators. In this...

This data release provides R scripts for estimating future stream water quality using Weighted Discharge on Time Discharge and Season for Projection (WRTDS-P). The technique is tested against hold-out data and is applied to four drought scenarios in the Delaware River Basin (DRB). The scripts retrieve WRTDS models from an existing data release for 39 sites in the DRB with observations...

High-resolution bathymetric maps were compiled in support of hydrogeologic research conducted by the U.S. Geological Survey Caribbean-Florida Water Science Center in a region offshore of southeastern Florida (Cunningham and others, 2024). Sub-circular to circular seafloor depressions were identified and mapped during 2016-2024 using established and new multibeam-bathymetry of the Miami...

The Highland Lakes are a chain of five reservoirs (Lake Buchanan, Inks Lake, Lake Lyndon B. Johnson, Lake Marble Falls, and Lake Travis) on the Colorado River of central Texas that are collectively managed by the Lower Colorado River Authority (LCRA). Since 2013 the LCRA has used a combination of Soil and Water Assessment Tool (SWAT, version 2005 [Neitsch and others, 2005] or 2009...

These data, modified from Horton and San Juan (2016), are a consolidation of point and polygon features representing mine and prospect-related symbols shown on U.S. Geological Survey (USGS) 7.5- and 15-minute topographic maps from the Historical Topographic Map Collection (HTMC). This consolidation supports more accurate counts of mine features represented in the database, which are...

This data set represents laboratory measurements conducted on a suite of select 53 pegmatite and host rock samples to better spectrally characterize complex pegmatite minerals. Of these 53 samples that were measured and analyzed, this includes 24 samples collected from the Morefield Mine, Amelia County, VA, six samples from the Martin-Marietta Amelia Quarry, Amelia County, VA, three...
