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.

High-resolution geophysical data collected along the Mississippi River Delta front offshore of southeastern Louisiana, U.S. Geological Survey Field Activity 2017-003-FA

High resolution bathymetric, sea-floor backscatter, and seismic-reflection data were collected offshore of southeastern Louisiana aboard the research vessel Point Sur on May 19-26, 2017, in an effort to characterize mudflow hazards on the Mississippi River Delta front. The primary objective of this cruise was to assess the suitability of sea-floor mapping and shallow subsurface imaging tools...

USGS Spectral Library Version 7 Data

Researchers at the USGS Spectroscopy Laboratory have measured the spectral reflectance of thousands of materials in the lab and compiled them in the USGS Spectral Library.  Detailed sample descriptions are provided with the spectra, including the results of X-ray Diffraction, Electron Probe Micro-Analysis, and other analytical methods.

Annual Variation Birds as indicators of contaminants in the Great Lakes

Tachycineta bicolor eggs and nestlings were collected from sites across the Great Lakes to quantify normal annual variation in total polychlorinated biphenyl (PCBs) exposure and to validate the sample size choice in earlier work. A sample size of 5 eggs or 5 nestlings per site was adequate to quantify exposure to PCBs in tree swallows given the current exposure levels and variation.

Ethanol and sodium acetate as a preservation method to delay degradation of environmental DNA: Data

This data contains environmental DNA (eDNA) sample assay results that were collected from water samples taken from a tank housing Asian carp and placed either on ice or at room temperature. At both treatment temperatures, water samples were left untreated or were treated with an ethanol and sodium acetate solution (EtOH-NaAc).

Distribution and foraging patterns of common loons on Lake Michigan with implications for exposure to type E avian botulism: Data

Common loons staging on the Great Lakes during fall migration are at risk to episodic outbreaks of type E botulism. Information on distribution, foraging patterns, and exposure routes of loons are needed for understanding the physical and ecological factors that contribute to avian botulism outbreaks. Aerial surveys were conducted to document the spatiotemporal distribution of common

Data compilation of soil respiration, moisture, and temperature measurements from global warming experiments from 1994-2014

This dataset is the largest global dataset to date of soil respiration, moisture, and temperature measurements, totaling >3800 observations representing 27 temperature manipulation studies, spanning nine biomes and nearly two decades of warming experiments. Data for this study were obtained from a combination of unpublished data and published literature values.

Continuous and optimized 3-arcsecond elevation model for United States east and west coasts

This data release contains the compilation of multiple elevation products into a continuous digital elevation model at a resolution of 3-arcseconds (approximately 90 meters) from the terrestrial landscape to the seafloor for the contiguous U.S. and portions of Mexico and Canada, focused on the coastal interface.

Bathymetry and Backscatter Intensity of the Sea Floor South of Long Island, New York

Surveys of the bathymetry and backscatter intensity of the sea floor south of Long Island, New York, were carried out in November 1998 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed. 

The area was mapped by the U.S. Geological Survey with support from the Canadian Hydrographic Service and the University of New Brunswick.

Bathymetry and backscatter intensity of the sea floor of the Historic Area Remediation Site in 1996, 1998, and 2000

Surveys of the bathymetry and backscatter intensity of the sea floor of the Historic Area Remediation Site (HARS), offshore of New York and New Jersey, were carried out in 1996, 1998, and 2000 using a Simrad EM1000 multibeam echosounder mounted on the Canadian Coast Guard ship Frederick G. Creed
