Science Datasets

狠狠噜天天噜日日噜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.

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'. G

Electrical resistivity tomography processed data on irrigated fields at Fort Irwin National Training Center, San Bernardino County, California, 2019-2020

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 a

Fluvial transport of bedload, suspended sediment, and silicate solutes in watersheds of western Oregon and northwestern California (1901-2016)

These data sets contain the estimated fluvial transport of bedload, suspended sediment, and silicate solutes in the watersheds of western Oregon and northwestern California. The estimates for bedload represent mean conditions that existed during the 20th century, the estimates for suspended sediment represent mean conditions that existed between 1983 and 2012, and the estimates for silica

Mean annual loads of suspended sediment, total suspended solids, and silicate solutes at selected fixed water-quality stations in western Oregon and northwestern California (1951-2016)

This data set contains mean annual loads of suspended sediment, total suspended solids, and dissolved silicate minerals for select watersheds of western Oregon and northwestern California between water years 1951 and 2016. The loads were estimated using the USGS Fluxmaster program with no detrending, which is equivalent to the loads estimated using the USGS LOADEST program.
