Irrigated field characterization at Fort Irwin National Training Center, San Bernardino County, California, 2018-2020 Irrigated field characterization at Fort Irwin National Training Center, San Bernardino County, California, 2018-2020
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...
Data from visual encounter and acoustic monitoring surveys targeting amphibians and reptiles in Big Thicket National Preserve in southeast Texas from August 2010 to September 2018 Data from visual encounter and acoustic monitoring surveys targeting amphibians and reptiles in Big Thicket National Preserve in southeast Texas from August 2010 to September 2018
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.
Descriptions, Depth to Refusal, and Field-Saturated Hydraulic Conductivity of Soils on the Arctic Coastal Plain of Alaska, 2012-2016 Descriptions, Depth to Refusal, and Field-Saturated Hydraulic Conductivity of Soils on the Arctic Coastal Plain of Alaska, 2012-2016
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'...
Mean annual loads of suspended sediment, total suspended solids the dissolved silicate minerals in watersheds of western Oregon and northwestern California (1951-2016) Mean annual loads of suspended sediment, total suspended solids the dissolved silicate minerals in watersheds of western Oregon and northwestern California (1951-2016)
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...
Selenium concentrations in food webs of Lake Koocanusa in the vicinity of Libby Dam (MT) and the Elk River (BC) as the basis for applying ecosystem-scale modeling, 2008-2018 Selenium concentrations in food webs of Lake Koocanusa in the vicinity of Libby Dam (MT) and the Elk River (BC) as the basis for applying ecosystem-scale modeling, 2008-2018
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...
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...
