Science Datasets
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.
Benthic Foraminiferal Data from Sedimentary Cores Collected in the Grand Bay (Mississippi) and Dauphin Island (Alabama) Salt Marshes
Microfossil (benthic foraminifera) data from coastal areas were collected within the Grand Bay National Estuarine Research Reserve and Grand Bay National Wildlife Refuge, Grand Bay, Mississippi/Alabama; Bon Secour National Wildlife Refuge on Cedar Island and Little Dauphin Island, Alabama; and land around Dauphin Island, Alabama.
Archive of Ground Penetrating Radar and Differential Global Positioning System Data Collected in April 2016 from Fire Island, New York
Archive of ground penetrating radar (GPR) and post-processed differential global positioning system (DGPS) data collected from beach and back-barrier environments on Fire Island, New York, April 6–13, 2016. Data can be used to map shallow subsurface sediments and to image deeper stratigraphic features.
Archive of digitized analog boomer and minisparker seismic reflection data collected from the Northern Gulf of Mexico: 1981, 1990, and 1991
Archive of HRSP profiles annotated with header information, converted SEG-Y files, navigation data, and cruise trackline shapefiles. Data collection dates and locations: July 1–15, 1981, Chandeleur and Mississippi Sounds; April 9–23, 1981, Gulf of Mexico; June 21–27, 1990, Mississippi Sound and the Gulf of Mexico; July 10–11 and July 21–27, 1991, Mississippi Sound and the Gulf of Mexico.
Aerial imagery and photogrammetric products from unmanned aerial systems (UAS) flights over the Lake Ontario shoreline at Sodus Bay, New York, July 12 to 14, 2017
This data release includes images tagged with locations determined from the UAS GPS; tables with updated estimates of camera positions and attitudes based on the photogrammetric reconstruction; tables listing locations of the base stations, ground control points, and transect points; geolocated, RGB-colored point clouds; orthomosaic images; and digital elevation models for each of the regions...
2018 Known and Probable Grizzly Bear Mortalities in the Greater Yellowstone Ecosystem
Known mortality - a carcass is in hand; Probable mortality - evidence strongly suggests a mortality has occurred but no carcass is recovered.

Archive of Digitized Analog Boomer Seismic Reflection Data Collected during USGS Cruise USFHC in Mississippi Sound and Bay St. Louis, September 1989
Archive of HRSP profiles annotated with header information, converted SEG-Y files, navigation data, cruise trackline files, logbooks, and annotated/core location maps. Geophysical surveys were conducted between September 13 and 19, 1989, within Bay St. Louis and the adjacent Mississippi Sound offshore of Hancock County, Mississippi.
Detection Limits
(Intro) (mg = µg) Elemental detection limits for NAA are variable because some elements become very radioactive–, and can be determined at very low levels while other elements do not become very radioactive or have very short half–lives (less than 10 seconds). Activation analysis determines the total mass of an element in a sample.
Sea-Floor Sediment Samples, Seabed Imagery, and CTD Instrument Data Collected on Stellwagen Bank in August 2017, U.S. Geological Survey Field Activity 2017-043-FA
The data collected in this study will aid research on the ecology of fish and invertebrate species that inhabit the region. On August 22 and 23, 2017, the U.S. Geological Survey, in collaboration with the Stellwagen Bank National Marine Sanctuary, conducted a research cruise aboard the Sanctuary’s Research Vessel Auk, visiting 39 locations within the sanctuary.
