Data

In 2015, scientists from the U.S. Geological Survey St. Petersburg Coastal and Marine Science Center (USGS SPCMSC) conducted sediment sampling surveys on and around the barrier islands of Dauphin Island and Little Dauphin Island, Mobile County, Alabama (AL). The study investigated the surficial sediment surrounding Dauphin Island and surrounding environments to inform sediment transport model scen

Four indices—the Langelier Saturation Index (LSI), Ryznar Stability Index (RSI), Puckorius Scaling Index (PSI), and the Potential to Promote Galvanic Corrosion (PPGC) — in addition to an analysis which normalized the results from the existing indices, the Combined Index (CI), were used to assess the potential corrosivity of groundwater in Louisiana.

This data set consists of 19 wideband magnetotelluric (MT) and 23 transient electromagnetic (TEM) soundings collected by the U.S. Geological Survey in June 2020 as part of the Umatilla Indian Reservation Geothermal Resources Assessment: Phase 2 project. Each MT station had 4 components, 2 orthogonal magnetic induction coils and 2 horizontal orthogonal electric dipoles. Data were collected for an a

Phenological dynamics of terrestrial ecosystems reflect the response of the Earth's vegetation canopy to changes in climate and hydrology and are thus important to monitor operationally.  The cheatgrass and medusahead phenology in the Snake River Plain (SRP) and Northern Basin and Range (NBR) based on 30m near seamless Harmonized Landsat and Sentinel-2 (HLS) Normalized Difference Vegetation Index

Catalog datasets in support of publication, "A Decade of Precursory Seismicity at Mauna Loa: 2013-2022". The earthquake catalogs begin April 1, 2009 and extend to January 1, 2023. The entire dataset has been generated with the ANSS Quake Management System (AQMS), which has the real-time software package Earthworm at its core. Automated and reviewed locations use the Hypoinverse location program an

This data set is a geospatial database for the 1:24,000 scale Geologic Map of the Southern Stillwater Range, Nevada (John and others, 2024). It contains all the geologic spatial information and text unit descriptions from the printed map, in the Geologic Map Schema (GeMS) format for digital geologic maps maintained by the USGS’ National Cooperative Geologic Mapping Program (NCMGP). Base map data a

The dataset includes .csv spreadsheets which provide whole rock geochemical data for the alkaline silicate and carbonatite samples from which apatite and monazite were analyzed, as well as geochemical data collected via electron microprobe and laser ablation ICP-MS for the apatite and monazite mineral grains. Whole rock geochemical data were collected by SGS Labs, except carbonatite samples 84-6-1

There are 9 datasets. one distance sampling dataset, 4 resource selection datasets, and 4 outputs from bootstrapped resource selection models the use the estimated correction factor. The 4 resource selection datasets have data that can be used in a binomial generalized linear mixed effect model to create the correction factor. The distance sampling data set is used to estimate density, and the 4 r

The U.S. Geological Survey (USGS), in cooperation with Scott Air Force Base (SAFB), Illinois, assessed the effects of temporal land-use development in the Silver Creek Basin, the potential effects of projected changes in future precipitation, and the effects of added detention storage in selected tributaries near SAFB. A hydrologic model was used to simulate precipitation runoff and streamflows fo

The Kingshill aquifer resides under St. Croix, an Island in the U.S. Virgin Islands. The Island of St. Croix is mountainous in the northwestern and eastern regions of the island and the central and southwest regions contain rolling hills and plains. The Kingshill aquifer underlies the plains of St. Croix. The aquifer is composed primarily of limestone and marl and has a maximum saturated thicknes

The Rush Springs aquifer resides in west-central Oklahoma with an area of about 1,400 square miles. The aquifer consists of the Rush Springs Sandstone and the Marlow Formation which are part of the Whitehorse Group of Permian age (HA 730-E). The Rush Springs Sandstone has a maximum thickness of about 300 feet and the Marlow Formation has a maximum thickness of about 125 feet. The aquifer is prim

The Southern Nevada volcanic-rock aquifers reside in southern-central Nevada. This group of aquifers can be categorized into welded tuff, bedded tuff, and lava flow aquifers. Each of these categories possess different physical characteristics and have varying degrees of welding and number of interconnected joints. The lithology of these aquifers is primarily dependent on mode of eruption and cool
