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.

Soil properties dataset in the United States Soil properties dataset in the United States
The dataset consists of three raster GeoTIFF files describing the following soil properties in the US: available water capacity, field capacity, and soil porosity. The input data were obtained from the gridded National Soil Survey Geographic (gNATSGO) Database and the Gridded Soil Survey Geographic (gSSURGO) Database with Soil Data Development tools provided by the Natural Resources...
Laboratory results for anthropogenic bioactive chemicals in the Illinois Waterway upstream and downstream of the bigheaded carp population front (2015; ver. 2.0, March 2020) Laboratory results for anthropogenic bioactive chemicals in the Illinois Waterway upstream and downstream of the bigheaded carp population front (2015; ver. 2.0, March 2020)
Two non-native bigheaded carp species have invaded the Illinois River system and are a potential threat to the Great Lakes ecosystem. Discharges from industry, wastewater treatment plants, and urban and agricultural runoff, may be a factor contributing to the stalling of the upstream movement of the bigheaded carp population front near Illinois Waterway mile 278. In 2015, the U.S...
Long-term soil carbon data and accretion from four marsh types in Mississippi River Delta in 2015 Long-term soil carbon data and accretion from four marsh types in Mississippi River Delta in 2015
The Mississippi River Deltaic Plain has extensive marsh habitats (fresh, intermediate, brackish, and saline) where soil cores were collected to a depth of 100 cm at 24 sites to assess long-term carbon accumulation rates and coast-wide burial rates. Each core was sectioned into 2-cm depth intervals, and select intervals were analyzed for percent moisture, bulk density, total carbon, and
Trace metals in water and biota in and near headwater streams in the Colorado Mineral Belt Trace metals in water and biota in and near headwater streams in the Colorado Mineral Belt
This data release includes sampling location data, field-collected water chemistry data, cation and anion concentration data for water and tissues of submerged aquatic vegetation, aquatic insect larvae, adult aquatic insects and riparian spiders from 35 first- and second-order sub-alpine streams that ranged over several orders of magnitude in metal concentrations but were similar in...
Time-lapse color photography of Milford Lake, Kansas, June through November 2017 and June through November 2018 Time-lapse color photography of Milford Lake, Kansas, June through November 2017 and June through November 2018
This U.S. Geological Survey (USGS) Data Release provides time-lapse color photography collected from three sites at Milford Lake, Kansas, during June through November 2017 and June through November 2018. Photographic images are displayed using a .mp4 common multimedia format. Time-lapse cameras were used to visually capture cyanobacterial accumulations and movement throughout Milford...
