Data and Tools

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.

Walrus Haulout Outlines Apparent from Satellite Imagery Near Point Lay Alaska, Autumn 2018-2020

These data are in three folders of Keyhole Markup Language (KML) geospatial polygons representing the outlines of walrus herds apparent in satellite imagery. Each KML file contains one or more geospatial polygons of walrus herd outlines created by one observer who visually interpreted the images. The attribute values from all KML files are collected in a CSV table included with this data...

Innate Immunity and Stress and Reproductive Hormone Metrics for Southern Beaufort Sea Polar Bears, 2013-2015

These were data collected from polar bears from the Southern Beaufort Sea during the spring between 2013 and 2015. Data include individual id, demographic characteristics, year, status for the current and prior year regarding use of land, concentrations of stress response and reproductive hormones, blood-based biomarker measures indicative of fasting, body mass index, and body condition.

Structure from motion products associated with UAS flights in Sandwich, Massachusetts between January 2016 - September 2017

Low-altitude (80-100 meters above ground level) Unmanned Aircraft Systems (UAS) imagery of Town Neck Beach in Sandwich, Massachusetts, were used in a structure-from-motion (SfM) photogrammetry workflow to create high-resolution topographic datasets. Imagery was collected at close to low tide on twelve days to observe changes in beach and dune morphology.

Blood Parasite Infection, Body Mass, and Survival Data from Emperor Geese (Anser canagicus), Yukon-Kuskokwim Delta, Alaska, 2006-2016

This dataset provides two tables of blood parasite infection data collected from Emperor Geese (Anser canagicus) on Yukon-Kuskokwim Delta, Alaska, 2006-2016. Three genera of blood parasites (Leucocytozoon, Haemoproteus, Plasmodium) were detected by molecular sequencing of a 479 bp fragment of the Cytochrome-b gene.

Río Icacos, Puerto Rico, Turbidity, FDOM, and Water Temperature, March 2017 to March 2019

The data were collected as part of a six-site study (four in New Hampshire and two in Puerto Rico) to understand how the relative variation in stream chemistry and discharge responds to variations in climate, represented by anomalies in precipitation and temperature, and how these responses differed in forests in these contrasting locations and climates.

Sedimentological and geotechnical analyses of marine sediment cores from the New England Mud Patch

 Ninety-two piston, vibra-, and gravity cores with a maximum length of 8.2 meters were collected from across the New England Mud Patch during a 2-leg, 10-day cruise aboard the R/V Endeavor in the spring of 2016. Geologic characterization and analysis of a subset of the cores was carried out at the Woods Hole Sediment Analysis Laboratory.

Donated AUV bathymetry and Chirp seismic-reflection data collected during Monterey Bay Aquarium Research Institute cruises in 2018-2019 offshore of south-central California

This data release consists of donated autonomous underwater vehicle (AUV) bathymetry and Chirp seismic-reflection data collected using an AUV in 2018 and 2019. The collection of these data was funded entirely by the Monterey Bay Aquarium Research Institute (MBARI), and the data have been donated to the USGS. The data were collected in collaboration with the USGS and BOEM

Composite multibeam bathymetry surface and data sources of the southern Cascadia Margin offshore Oregon and northern California

Bathymetry data from various sources, including newly released 2018 and 2019 multibeam data collected by NOAA and the USGS, were combined to create a composite 30-m resolution multibeam bathymetry surface of the southern Cascadia Margin offshore of Oregon and northern California. The bathymetry data are available as a 30-m resolution geoTIFF file, accompanied by a polygon shapefile

Historical shorelines and morphological metrics for barrier islands and spits along the north coast of Alaska between Cape Beaufort and the U.S.-Canadian border, 1947 to 2019

A suite of morphological metrics were derived from existing shoreline and elevation datasets for barrier islands and spits located along the north-slope coast of Alaska between Cape Beaufort and the U.S.-Canadian border. This dataset includes barrier shorelines and polygons attributed with morphological metrics from five time periods: 1950s, 1980s, 2000s, 2010s, and 2020s.
