The U.S. Army Fort Irwin National Training Center (NTC), approximately 35 miles north-northeast of Barstow, California, obtains all of its potable water supply from three groundwater basins (Irwin, Langford, and Bicycle Basins) within the NTC boundaries. In these basins, groundwater withdrawals exceed natural recharge, resulting in water-level declines. However, managed aquifer recharge using trea

This dataset contains data from visual encounter and acoustic surveys in Big Thicket National Preserve in Texas from August 2010 to September 2018. This dataset also includes salinity measurements from nine salinity loggers deployed in the study area.

This dataset includes soil data collected from various landscapes adjacent to thaw ponds on the North Slope of Alaska between 2012 and 2018. The landscapes include ice-rich polygonal ground found on basin uplands, as well as bluffs and lake edges. At each site a visual description of soil type and texture was performed, and a permafrost probe was used to determine a 'depth to refusal'. Given that

This data release includes three categories of data that were compiled as part of a study of sediment and solute transport and landscape denudation in watersheds of western Oregon and northwestern California: 1) mean annual loads of suspended sediment, total suspended solids, and silicate solutes at fixed water-quality stations; 2) fluvial transport of bedload, suspended sediment, and silicate sol

This Data Release presents multi-agency data for selenium concentrations in ecosystem media that includes water column, suspended particulate material, zooplankton, invertebrates, and fish. Because the data are compiled from multiple sources, the significant figures used to report contaminant concentrations and other metrics may not be internally consistent. These data will serve as the basis for

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 conducted by th

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 have triggere

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 and humidity

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; photosyntheticall

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 newly acqui

The Mars 2020 rover will explore Jezero crater, Mars to investigate an ancient delta for evidence of past microbial life and to better understand the geologic history of the region. The landing system onboard Mars 2020 will use technology developed at the Jet Propulsion Laboratory (JPL) called Terrain Relative Navigation (TRN), which will enable the spacecraft to autonomously avoid hazards (e.g.,
