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.

Spatial Coverage for Estimated Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA Spatial Coverage for Estimated Baseflow for Streams Containing Endangered Atlantic Salmon in Maine, USA
The U.S. Geological Survey (USGS) developed a regression model for estimating mean August baseflow per square mile of drainage area in cooperation with National Oceanic and Atmospheric Administration (NOAA) to help resource managers assess relative amounts of baseflow in streams with Maine Atlantic Salmon habitat (Lombard and others, 2021). The model was applied to each reach of a stream...
Population genetic data for three at-risk tiger beetles Habroscelimorpha dorsalis dorsalis, H. d. media, and Ellipsoptera puritana Population genetic data for three at-risk tiger beetles Habroscelimorpha dorsalis dorsalis, H. d. media, and Ellipsoptera puritana
This dataset includes microsatellite genotypes for 16 collections of tiger beetles (Ellipsoptera puritana) distributed in Connecticut and Maryland, United States and 44 collections of Habroscelimorpha dorsalis dorsalis and 14 collections of H. d. media distributed from Massachusetts to Florida, United States.
Data release for Predicting the impacts of future sea level rise on specialist snake species in the imperiled pine rockland ecosystem of South Florida Data release for Predicting the impacts of future sea level rise on specialist snake species in the imperiled pine rockland ecosystem of South Florida
Approximately 90% of pine rockland habitat in South Florida and the Florida Keys, USA, has been lost, fragmented, and degraded due to urbanization and other anthropogenic disturbances. Low-lying islands and coastal areas are also becoming increasingly vulnerable to sea-level rise and high tide flooding, which is rapidly increasing in frequency, depth, and extent, putting these areas and...
Regeneration trends along climate gradients in Taxodium distichum forest of the southeastern United States, 2007-2019 Regeneration trends along climate gradients in Taxodium distichum forest of the southeastern United States, 2007-2019
Data provided are the volumes of cypress cones, collected in the North American Baldcypress Swamp Network along the Mississippi River Alluvial Valley (southern Illinois to southern Louisiana, and Gulf of Mexico, east Texas to west Florida Panhandle, 2007 - 2019.
Geophysical characterization of geothermal resources on the Umatilla Indian Reservation in northeast Oregon Geophysical characterization of geothermal resources on the Umatilla Indian Reservation in northeast Oregon
During the summers of 2017 and 2020, our team collected gravity, ground magnetic (ATV and hiked traverses), paleomagnetic and rock property (density and susceptibility) data on the Umatilla Indian Reservation (UIR) in northeast Oregon to aid in characterizing subsurface stratigraphy using 2D and 3D modeling methods. This data was integrated with conductance surfaces from a 3D...
Developing bare-earth digital elevation models from structure-from-motion data on barrier islands, Dauphin Island, AL, 2018-2019 Developing bare-earth digital elevation models from structure-from-motion data on barrier islands, Dauphin Island, AL, 2018-2019
This U.S. Geological Survey data release includes bare-earth digital elevation models (DEMs) that were produced by removing elevation bias in vegetated areas from structure-from-motion (SfM) data products for two sites on Dauphin Island, Alabama. These data were collected in the late fall of 2018 and spring of 2019. In addition to the bare-earth DEMs, this data release also includes...
