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.

Multibeam Bathymetry Data Collected in 2016 from Grand Bay Alabama/Mississippi Multibeam Bathymetry Data Collected in 2016 from Grand Bay Alabama/Mississippi
The U.S Geological Survey (USGS) St. Petersburg Coastal and Marine Science Center (SPCMSC) conducted a reconnaissance multibeam bathymetry (MBB) survey in Grand Bay Alabama/Mississippi on May 12th, 2016, as an assessment of the shallow water capabilities of a Teledyne Reson SeaBat T50-P multibeam echosounder. The survey is a part of an ongoing wetland/estuarine sediment study being...
Field observations of ground failure triggered by the 2020 Puerto Rico earthquake sequence Field observations of ground failure triggered by the 2020 Puerto Rico earthquake sequence
This dataset consists of over 800 field observations of ground failure (landslides, lateral spreading, and liquefaction) and other damage triggered by the 2019-2020 Puerto Rico earthquake sequence. The sequence started with a M4.7 earthquake on 28 December 2019, followed by many more earthquakes, including 15 larger than M5 (as of 7 July 2020). The M6.4 mainshock, which is thought to...

This dataset includes the following measurements made over a managed lawn at Fort Logan Cemetery in Denver Colorado in 2011 and 2012. (No measurements were made in winter months: December, January, February). 1) half hourly eddy covariance measurements of evapotranspiration and fluxes of carbon dioxide and sensible heat 2) half hour averages of solar and net radiation, air temperature...
Eddy covariance measurements of ET, CO2 and Energy Fluxes, and, ancillary data for the Rocky Flats National Wildlife Refuge West site Eddy covariance measurements of ET, CO2 and Energy Fluxes, and, ancillary data for the Rocky Flats National Wildlife Refuge West site
This dataset includes the following measurements made over a xeric tall grass prairie in the southwest portion of Rocky Flats National Wildlife Refuge in 2011 and 2012: 1) half hourly eddy covariance measurements of latent heat flux (evapotranspiration) and fluxes of carbon dioxide and sensible heat, and friction velocity (U star) 2) half hour averages of solar and net radiation
Density and magnetic susceptibility measurements on Precambrian rocks in the Iron Mountain-Menominee region, Michigan-Wisconsin Density and magnetic susceptibility measurements on Precambrian rocks in the Iron Mountain-Menominee region, Michigan-Wisconsin
The U.S. Geological Survey (USGS) collected rock physical property measurements to help understand causative sources of gravity and magnetic survey anomalies in the Iron Mountain-Menominee region, Michigan-Wisconsin. A total of 2,356 measurements of magnetic susceptibility and density from 152 locations have been conducted on Precambrian rocks. The measurements aid in interpretation of...
