Data

This data release includes snow depth and snow water equivalent (SWE) for the water year 2025 during ten separate field campaigns that took place between late December and late May. The field area is comprised of 703 surveyed points in, on the perimeter of, and surrounding six flat field (‘no_slope’) forest openings, four northern hillslope aspect (‘north_slope’) forest openings and four...

This data release contains SnowModel snow evolution simulation output from water years 2022 to 2023 (October 1, 2021, through September 30, 2023) on a 100-meter (m) geospatial grid for a 3 kilometer (km) × 2 km model domain near Coal Creek off Coal Bank Pass in the San Juan Mountains in southwest Colorado, USA. The three quantities simulated for this release were snow water equivalent...

Soil data includes carbon (total, organic, mineral-associated, particulate-organic) and texture. Bulk density data includes bulk density values used to calculate carbon stocks. Plant data includes microsite coverage percents and sagebrush demographics. Data is from uninvaded and cheatgrass invaded points near Grand Junction, Colorado and Rock Springs, Wyoming in October and November 2023...

This data release represents samples collected in 1981 along a series of five marine terraces between Ano Nuevo and Santa Cruz in California as a part of a U.S. Geological Survey project led by Dennis Marchand to study soil chronosequences in the Western United States. These sequential surfaces of soils have similar key elements for development in the slope, climate, vegetation, and...

The Everglades Vulnerability Analysis (EVA) is a series of connected, modular Bayesian networks that predict the response of several Everglades indicators of ecosystem health to changes in hydrology, salinity, and the landscape. We created a soil depth layer for use in the sawgrass peat module by using universal kriging to estimate soil depth at a 400-meter resolution for individual...

Soil cores were collected across the marshes of Don Edwards San Francisco Bay National Wildlife Refuge in California to assess belowground properties and for radioisotope dating. Data from the soil cores include dry bulk density, organic matter proportion, carbon, and accretion rates. These data were then used to calibrate a wetland model (WARMER3) to assess future elevation and...

California’s wildfires are setting historic records for length, size, and severity (Safford and others, 2022, Kreider and others, 2024). These wildfires are altering soil processes like infiltration rates and carbon cycling over increasingly large areas (Staley and others, 2017; Kelly and others, 2020; Baur and others, 2024; Dow and others, 2024). In northern California, it is unclear...

The Falcon Refinery Superfund site (hereinafter referred to as “the site”) is in an unincorporated area of San Patricio County, approximately one mile southeast of Ingleside, Texas. The site is an inactive petroleum refinery that operated during the 1980s and consisted of 32 aboveground storage tanks (ASTs) used to store petroleum products. Since 2004, many of these ASTs have been...

This product is a dataset of volumetric soil-water content and soil temperature in an area affected by wildfire in the Boulder Creek watershed, in the Colorado Front Range, USA. The data contained in this archive continue through 7 years of recovery following a wildfire in 2010. Automated sensors (Decagon Devices, 5TE and 5TM) were used to collect the data at 1-minute and 5-minute...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB) and the Oka' Institute, constructed a Soil-Water-Balance (SWB) model of the eastern part of the Arbuckle-Simpson aquifer in south-central Oklahoma. The SWB model was used to estimate recharge to the eastern part of the Arbuckle-Simpson aquifer between January 2019 and December 2022 for...

This archive contains the data used to (1) summarize the hydrogeology and update the hydrogeologic framework of the Antlers aquifer in southeastern Oklahoma, and (2) develop a conceptual groundwater-flow model and water budget to estimate recharge to the Antlers aquifer during 1980–2022 as part of a hydrologic investigation (the model documentation report is available at https://doi.org...

The U.S. Geological Survey (USGS), in cooperation with the Oklahoma Water Resources Board (OWRB), constructed a Soil-Water-Balance (SWB) model of the Red River alluvial aquifer east of Lake Texoma in southeastern Oklahoma. Although the SWB model active area extends into parts of Texas and Arkansas, the SWB model was used to estimate recharge to the Red River alluvial aquifer between...
