PRISM Pliocene-Pleistocene Planktic Foram Taxonomy PRISM Pliocene-Pleistocene Planktic Foram Taxonomy
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...
Scripts for projecting stream water quality using Weighted Regression on Time Discharge and Season (WRTDS) in the Delaware River Basin Scripts for projecting stream water quality using Weighted Regression on Time Discharge and Season (WRTDS) in the Delaware River Basin
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 of deep-water sub-circular to circular seafloor depressions offshore of southeastern Florida High-resolution bathymetric maps of deep-water sub-circular to circular seafloor depressions offshore of southeastern Florida
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...
Harmful Algal Bloom Modeling Framework for the Highland Lakes, Colorado River, Texas, 1984–2018 Harmful Algal Bloom Modeling Framework for the Highland Lakes, Colorado River, Texas, 1984–2018
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...
Consolidated Prospect- and Mine-Related Features from U.S. Geological Survey 7.5- and 15-Minute Topographic Quadrangle Maps of the United States Consolidated Prospect- and Mine-Related Features from U.S. Geological Survey 7.5- and 15-Minute Topographic Quadrangle Maps of the United States
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...
Data (VNIR-SWIR reflectance, TIR emissivity, XRD and ATR-FTIR) Supporting Analyses of NYF Pegmatite and Garnet-Biotite Gneiss Rocks from Amelia County, Virginia Data (VNIR-SWIR reflectance, TIR emissivity, XRD and ATR-FTIR) Supporting Analyses of NYF Pegmatite and Garnet-Biotite Gneiss Rocks from Amelia County, Virginia
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...
