Data

This data release contains the boundaries of assessment units, assessment input data, and resulting fact sheet data tables for the assessment of undiscovered oil and gas resources in the offshore East Africa and Seychelles region. The Assessment Unit is the fundamental unit used in the National and Global Oil and Gas Assessment Project for the assessment of undiscovered oil and gas resources. The

The dataset documents results from particle size analysis (PSA) conducted on a suite of sediment samples from U.S. Army Base Fort Drum, Jefferson County, New York. Most of the PSA samples were collected from representative cells in a series of five portable optically stimulated luminescence (OSL) grids, here denoted G1 through G5, to constrain variations in grain size. These samples were also coll

These data are geochemical analyses of Earthquake Flat Pyroclastics pumice and phase equilibria experiments.

Soil cores were collected in mangrove forests across Pohnpei, Federated States of Micronesia to understand spatial variation in accretion rates. Cores were dated using lead-210 and processed for bulk density and organic matter percent through loss-on-ignition analysis. A total of 30 cores were successfully dated across seven regions around the island.

These data were used to examine grammatical structures and patterns within a set of geospatial glossary definitions. Objectives of our study were to analyze the semantic structure of input definitions, use this information to build triple structures of RDF graph data, upload our lexicon to a knowledge graph software, and perform SPARQL queries on the data. Upon completion of this study, SPARQL que

The Aransas-Wood Buffalo population of whooping cranes migrates through the U.S. Great Plains twice annually, moving between wintering areas along coastal Texas and summering areas in and around Wood Buffalo National Park, Canada. These birds primarily migrate within a roughly 300-km-wide corridor that spans areas in Texas, Oklahoma, Kansas, Nebraska, South Dakota, North Dakota, and northwestern M

The Little Sequatchie River and Pryor Cove Creek watersheds are located in southern Tennessee and drain the eastern escarpment of the Cumberland Plateau to the Sequatchie River.  The Little Sequatchie River has the largest drainage area of any Sequatchie River tributary, with over 130 square miles in the topographic confines of the watershed.  The hydrology of both watersheds has been largely alte

Karst hydrologic systems are important resources in the state of Tennessee both as drinking water resources and as centers for possible biological diversity. These systems are susceptible to contamination due to the inherent connectivity between surface water and groundwater in karst landscapes. A partnership between the U.S. Geological Survey (USGS) and Tennessee Department of Conservation (TDEC)

Isotopic compositions (87Sr/86Sr, 143Nd/144Nd, 176Hf/177Hf, 206Pb/204Pb, 207Pb/204Pb, 208Pb/204Pb) and major oxide and trace element concentrations of Quaternary basalts, hawaiites, mugearites, benmoreites, and trachytes from northern Harrat Rahat, Kingdom of Saudi Arabia.

Two digital video cameras were temporarily installed at the U.S. Fish and Wildlife Service (USFWS) Pea Island National Wildlife Refuge (PINWR) in North Carolina (NC), as part of the DUring Nearshore Event eXperiment (DUNEX). DUNEX was a collaborative community-led experiment that took place in the fall of 2021 along the Outer Banks of NC, with the goal of improving the understanding, observational

A three-dimensional geologic map was created by assembling eight geologic cross sections derived from geologic mapping, potential field geophysics, and petroleum well logs. The central feature of the map is the San Andreas Fault, with many other prominent structural features depicted that express the regional transpressional tectonic setting. The subsurface interpretation was based on existing two
