Integrating land use land cover change into future scenarios of electricity systems - Data Release Integrating land use land cover change into future scenarios of electricity systems - Data Release
Modeled projections for deep decarbonization require large amounts of solar energy, which may compete with other land uses such as agriculture, urbanization, and conservation of natural lands. Existing capacity expansion models do not integrate land use land cover change (LULC) dynamics into projections. We explored the interaction between projected LULC and solar photovoltaic (PV)...
Landscape data compiled for fish health sites in and around the Chesapeake Bay Watershed. Landscape data compiled for fish health sites in and around the Chesapeake Bay Watershed.
These data include estimates of landcover and land use characteristics including high phytoestrogen crop cover, estimated pesticide applications, EPA PFAS facilities, nutrients from biosolids, and select climate (temperature and precipitation) variables summarized for several fish health sites in the eastern United States.
MODFLOW 6 models for simulating groundwater flow in the Mississippi Embayment with a focus on the Mississippi Delta MODFLOW 6 models for simulating groundwater flow in the Mississippi Embayment with a focus on the Mississippi Delta
This model archive contains the model files for the MERAS 3 and Mississippi Delta groundwater flow models documented in the U.S. Geological Survey Scientific Investigations Report 2023-5100. The MERAS 3 model provides a simplified representation of groundwater flow in the Mississippi Embayment Regional Aquifer Study (MERAS) area for the period of 1900 through 2018, with the primary goal...
Rock mass quality and structural geology observations in northwest Prince William Sound, Alaska from the summer of 2021 Rock mass quality and structural geology observations in northwest Prince William Sound, Alaska from the summer of 2021
Multiple subaerial landslides adjacent to Prince William Sound, Alaska (for example, Dai and others, 2020; Higman and others, 2023; Schaefer and others, 2024) pose a threat to the public because of their potential to generate ocean waves (Dai and others, 2020; Barnhart and others, 2021; Barnhart and others, 2022) that could impact towns and marine activities. One bedrock landslide on the...
Mercury Methylation Assay Along a Salinity Gradient in Coastal Peat Soils in the Florida Everglades Mercury Methylation Assay Along a Salinity Gradient in Coastal Peat Soils in the Florida Everglades
This data was collected as part of a laboratory study examining the effects of sea level rise on mercury (Hg) methylation and demethylation rates in peat cores collected from the Florida Everglades. Peat cores were collected from a freshwater region of the Everglades, Water Conservation Area 3, in 2022 and taken to the University of California-Davis for methylation and demethylation...
USGS National and Global Oil and Gas Assessment Project—East Africa and Seychelles Provinces: Assessment Unit Boundaries, Assessment Input data, and Fact Sheet Data Tables USGS National and Global Oil and Gas Assessment Project—East Africa and Seychelles Provinces: Assessment Unit Boundaries, Assessment Input data, and Fact Sheet Data Tables
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...
Particle size distribution data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver. 1.1, May 2025) Particle size distribution data from U.S. Army Base Fort Drum, Jefferson County, New York, 2023 (ver. 1.1, May 2025)
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...

Soil Characteristics and Accretion Rates in Mangrove Forests across Pohnpei, Federated States of Micronesia Soil Characteristics and Accretion Rates in Mangrove Forests across Pohnpei, Federated States of Micronesia
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.
Grammar transformations of topographic feature type annotations of the U.S. to structured graph data Grammar transformations of topographic feature type annotations of the U.S. to structured graph data
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...
Whooping crane use around Air Force Bases in Oklahoma, 2017-2022 Whooping crane use around Air Force Bases in Oklahoma, 2017-2022
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...
Mapping karst groundwater flow paths and delineating recharge areas for springs in the Little Sequatchie and Pryor Cove watersheds, Tennessee Mapping karst groundwater flow paths and delineating recharge areas for springs in the Little Sequatchie and Pryor Cove watersheds, Tennessee
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...
