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.

Potential contaminant sources and other landscape variables summarized for NHDPlus Version 2.1 catchments within the Chesapeake Bay Watershed (ver. 2.0, June 2021)
This dataset consists of 262 variables which describe various known and suspected point and non-point sources of contaminants and endocrine disrupting compounds (EDCs) throughout the Chesapeake Bay Watershed. Contaminant data was summarized to the NHDPlus Version 2.1 catchment level (1:100K). Contaminant data summarized span a time range of 2001 to 2016 and include regulated facilities, pesticides
Missouri River Bend Classification
Management actions intended to increase growth and survival of pallid sturgeon (Scaphirhynchus albus) age-0 larvae on the Lower Missouri River require a comprehensive understanding of the geomorphic habitat template of the river. The datasets described here are intended to support decisions relating to where channel-reconfiguration projects should be located to optimize effectiveness of intercepti
Glass deformation experiments under hydrothermal conditions
Six time-series data files are included in this release. The files contain mechanical data (described in metadata file below) collected during deformation experiments performed on obsidian gouge. A detailed description of the experiments along with the data reduction procedures are provided in the published manuscript titled Conversion of wet glass to melt at lower seismogenic zone conditions: i
FishTail, Indices and Supporting Data Characterizing the Current and Future Risk to Fish Habitat Degradation in the Northeast Climate Science Center Region
Human impacts occurring throughout the Northeast and Midwest United States, including urbanization, agriculture, and dams, have multiple effects on the regions streams which support economically valuable stream fishes. Changes in climate are expected to lead to additional impacts in stream habitats and fish assemblages in multiple ways, including changing stream water temperatures. To manage str
Seed biomass from shallow coastal water areas along a salinity gradient in Barataria Bay, Louisiana (2015)
This dataset provides bi-monthly data on seed biomass collected in shallow water habitats across the fresh to saline gradient at coastal sites in Barataria Bay, Louisiana.
Seed biomass from shallow coastal water areas from Texas through Alabama, 2013-2015
This projects primary goal was to provide data on biomass of potential seed resources located within shallow water coastal areas within fresh to saline coastal waters of the northern Gulf of Mexico. The data set provides biomass of seeds, by species or lowest practical taxon from 2013, 2014 and 2015 across 384 randomly selected sites located in shallow water coastal areas. The data were collected
Prioritization of areas for open pine ecosystem restoration in the Southeastern United States: All Species
We used NLCD 2011, SSURGO, and SEGAP data to map the density of desired resources for open pine ecosystems and six focal species of birds and 2 reptiles within the historic range of longleaf pine east of the Mississippi River. Binary rasters were created of sites with desired characteristics such as land form, hydrology, land use and land cover, soils, potential habitat for focal species, and puta
Submerged aquatic vegetation and environmental data along a salinity gradient in Barataria Bay, Louisiana (2015)
This data set includes bi-monthly data on submerged aquatic vegetation species composition, percent cover, above and below ground biomass and environmental data at coastal sites across the fresh to saline gradient in Barataria Bay, LA.
Nonindigenous aquatic species and potential spread after Hurricane Irma
This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Irma. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along co
Nonindigenous aquatic species and potential spread after Hurricane Nate
This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Nate. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along co
Nonindigenous aquatic species and potential spread after Hurricane Maria
This map was created to help assess impacts on nonindigenous aquatic species distributions due to flooding associated with Hurricane Maria. Storm surge and flood events can assist expansion and distribution of nonindigenous aquatic species through the connection of adjacent watersheds, backflow of water upstream of impoundments, increased downstream flow, and creation of freshwater bridges along c
Water temperature in Three Sisters Springs, and water temperature and level in Magnolia Spring: Winter 2014-15
Water level and water temperature from Magnolia Spring were recorded with a level datalogger (HOBO U20-001-01-Ti; Onset Computer Corp., Bourne, MA) set to record every 15 min. The datalogger was attached to a Crystal River National Wildlife Refuge signpost (LAT 28.8913, LONG -82.5925). Data were reported in meters of water depth to the logger and degrees Celcius. Water temperature from Three Siste
