Data Releases
The data collected and the techniques used by USGS scientists should conform to or reference national and international standards and protocols if they exist and when they are relevant and appropriate. For datasets of a given type, and if national or international metadata standards exist, the data are indexed with metadata that facilitates access and integration.

Wetland transformations for three relative sea-level rise scenarios along the middle and upper Texas Coast, wetland current condition map and wetland transformation maps by decade, sea-level rise scenario, and coastal wetland drowning threshold (ver. 2.0, Wetland transformations for three relative sea-level rise scenarios along the middle and upper Texas Coast, wetland current condition map and wetland transformation maps by decade, sea-level rise scenario, and coastal wetland drowning threshold (ver. 2.0,
As sea levels rise, wetlands exposed to oceanic water can adapt to changing conditions through vertical development (i.e., soil surface elevation gains via biophysical feedbacks) and horizontal migration into upslope areas. Elevation-based models of wetland transformation from sea-level rise are often hampered from a variety of sources of uncertainty, including contemporary elevation and...
Multisource Discrete Chlorophyll Data in the Illinois River Basin, 1976–2023 Multisource Discrete Chlorophyll Data in the Illinois River Basin, 1976–2023
This data release contains discrete chlorophyll data, specifically corrected chlorophyll a, uncorrected chlorophyll a, and pheophytin pigments, from inland waters in the Illinois River Basin for 1981–2023. These data are discrete samples (collected in the field and analyzed in the laboratory) of plankton (suspended algae) and periphyton (benthic algae) from lakes, streams, rivers, canals...
Long-term change on barrier islands and barrier shorelines from extreme storms and restoration along the north central Gulf of Mexico coast Long-term change on barrier islands and barrier shorelines from extreme storms and restoration along the north central Gulf of Mexico coast
These data utilize existing land cover products and elevation information to provide information on changes on barrier islands and barrier shorelines along the north central Gulf of Mexico coast. Specifically, this data release includes information on changes in subaerial land, habitat types, and high-tide flooding for barrier islands and barrier shorelines along the north central Gulf...
Species of Greatest Conservation Need National Database 2005-2022 Species of Greatest Conservation Need National Database 2005-2022
The Species of Greatest Conservation Need National Database is an aggregation of lists from State Wildlife Action Plans. Species of Greatest Conservation Need (SGCN) are wildlife species that need conservation attention as listed in action plans. In this database, we have validated scientific names from original documents against taxonomic authorities to increase consistency among names...
Structure-from-Motion derived point clouds and orthomosaic images of reference sections of the Brallier and Foreknobs Formations, Baker, WV Structure-from-Motion derived point clouds and orthomosaic images of reference sections of the Brallier and Foreknobs Formations, Baker, WV
This dataset consists of Structure-from-Motion (SfM) - derived point clouds and highly detailed orthomosaic images of four roadcut exposures covering the upper part of the Harrell Shale, the full Brallier Formation, the full Foreknobs Formation, and the lower part of the Hampshire Formation at Baker, West Virginia. For each roadcut exposure, two datasets are published: an orthomosaic...
Uranium-lead isotopic data from the New Hampshire Plutonic Suite and metasedimentary rocks of the New Hampshire Sequence in the Bronson Hill anticlinorium from the Bellows Falls 7.5- x 15-minute quadrangle, Vermont and New Hampshire Uranium-lead isotopic data from the New Hampshire Plutonic Suite and metasedimentary rocks of the New Hampshire Sequence in the Bronson Hill anticlinorium from the Bellows Falls 7.5- x 15-minute quadrangle, Vermont and New Hampshire
This data release includes uranium-lead isotopic data collected from metaplutonic rocks of the New Hampshire Plutonic Suite and metasedimentary rocks of the New Hampshire Sequence. Rock samples were collected by Arthur Merschat, Greg Walsh, and Ryan McAleer. Samples were processed and analyzed by Arthur Merschat and Ryan McAleer. Uranium-lead isotopic data was collected using a sensitive...
