Data

The U.S. Geological Survey (USGS), in cooperation with the Galveston Bay Estuary Program, collected surface water samples for microplastics analysis from selected Galveston Bay, Texas tributaries. These data were collected to establish a baseline dataset documenting the distribution and extent of microplastic pollution within the watershed. This data release documents microplastic counts...

Ar/Ar geochronology is a versatile method that provides age constraints for a wide range of potassium-bearing rocks and minerals. It can be applied to understand the timing of volcanic eruptions, igneous intrusions, metamorphic or heating events, and alteration events, among other processes. The USGS Denver Argon Geochronology Laboratory produces data for multiple programs, including the...

We collected field-based vegetation data during the summer of 2024 on six islands within the Oregon Coast National Wildlife Refuge Complex, Oregon, U.S.A.: Goat Island, Hunters Island, North Crook Point Rock, Saddle Rock, Whaleshead Cove East Rock, and Whaleshead Cove West Rock. Data were collected by Oregon State University in collaboration with the U.S. Fish and Wildlife Service to...

The U.S. Geological Survey (USGS) simulated the drift of invasive carp eggs and larvae in the lower Sandusky River, Ohio, after the removal of Ballville Dam near Fremont, Ohio, using the Fluvial Egg Drift Simulator (FluEgg) 4.1.1 (Garcia and others, 2013; Domanski and Berutti, 2020; Domanski and others, 2021). The hydraulic inputs used in the FluEgg simulations were generated using a one

Analyses were conducted in 2026 to examine glaciolacustrine rhythmic laminations interpreted as annual layers (varves) in a suite of two sediment drill cores collected from Sheffield, Massachusetts in 2010. The dataset includes results from portable X-ray fluorescence (pXRF), particle size analysis (PSA), visible (color) and near-infrared spectrophotometry, and magnetic susceptibility...

These datasets were compiled to support the publication Mordensky et al. (2026) that discusses how supervised machine learning can be used to delineate zones that vary according to feature data and predict which locations in a given region are more favorable for geothermal activity. The datasets contained herein are the point data for the 53 publicly available input features organized by...

These datasets were compiled to support the publication Caraccioli, P.D., Mordensky, S.P., DeAngelo, J., Burns, E.R., Lipor, J.J., 2026, How Selecting Representative Training Sites and Features Can Improve Machine Learning Models for Hydrothermal Resource Favorability. Geothermics, 103833, https://doi.org/10.1016/j.geothermics.2026.103833 that details how training strategies (e.g., the...

New dating of lahar-killed trees underscores volcano hazards in the Puget Sound metropolitan area. Beginning as a landslide from the west flank of Mount Rainier, Washington, the Electron Mudflow swept more than 60 km down the Puyallup River drainage into areas now heavily populated. Wiggle-matching of seven radiocarbon ages from buried, bark-bearing Douglas-fir (Pseudotsuga menziesii)...

Daily measurements of evaporation using the Bowen ratio method were made at USGS station name LZ40 (USGS site number 265405080472100), a platform-based station constructed by the South Florida Water Management District (SFWMD) at the approximate center of Lake Okeechobee, Florida. Data collection began on November 15, 2012. Meteorological and environmental variables were measured every...

This data release provides coupling of Conterminous United States and several Canadian operational reservoirs used in recent hydrologic modeling studies to authoritative national hydrographic datasets used to identify, calibrate, model, and assess streamflow, water quantity, quality, and ecological resources. The National Inventory of Dams (NID) provides linkages to dams operated in the...

A Geographic Information System (GIS) shapefile and summary tables of irrigated agricultural land-use are provided for Hardee, Hillsborough, Manatee, Pinellas, and Polk Counties, Florida. These files were compiled through a cooperative project between the U.S. Geological Survey and the Florida Department of Agriculture and Consumer Services, Office of Agricultural Water Policy...

NASA’s lunar exploration objectives, which include both robotic and human missions to the surface, require data products with high spatial resolution and accuracy. Using rigorous photogrammetric methods, we have co-aligned thousands of high-resolution images from the Lunar Reconnaissance Orbiter Camera (LROC) Narrow Angle Camera (NAC) [Robinson et al. 2010] of the lunar north and south...
