Between 1900 and 1932, a copper (Cu) mine operated near Gay, Michigan, along the shore of Lake Superior, discharged approximately 22.8 million metric tons of waste material known as ‘stamp sands’...
-
The Fox River transports elevated loads of nitrogen and phosphorus to Lake Michigan. The increased concentration of N and P causes eutrophication of the lake, creating hypoxic zones and damaging...

This dynamic data release presents an aquatic reflectance product with 20-meter spatial resolution derived from Sentinel-2 satellite imagery for the conterminous United States using the...
-
The dataset provides a spatially explicit estimate of 2019 herbaceous annual percent cover predicted on May 1st with an emphasis on annual grasses. The estimate is based on the mean output of two...
-
Field observations of water and suspended-sediment fluxes were conducted at Benicia Bridge and Mallard Island during the 2019 water year wet season to capture suspended-sediment flux during...
-
The location of a point (or pixel) within the conterminous U.S. can be assigned based on its position relative to the Nation’s stream network. Two metrics are recognized: lateral position (LP) and...
-
This dataset contains the input (temperature and precipitation from climate models) and output from the Soil and Water Assessment Tool (SWAT) model runs using the Hydrologic and Water Quality...
-
This dataset includes CSV data files containing environmental data that may be associated with the occurrence and toxicity of the diatom Pseudo nitzschia in Frenchman Bay, Maine, that can form...
-
Sulfide- and chromite-bearing samples of the Basal and Ultramafic series of the Stillwater Complex are known to contain elevated concentrations of platinum-group elements (PGE). Thin sections were...
-
The "Broad-scale assessment of biophysical features in Colorado: Ecological Communities" raster dataset provides a hierarchical vegetation classification (vegetation type, ecological community,...
-
Infiltrometers are devices used to measure the infiltration rates of water into soils or porous media (Bouwer, 1986). Cylinder infiltrometers are generally constructed from metal shaped into...
-
A CE-QUAL-W2 river hydrodynamics and water temperature model was developed for a 21-mile reach of the Illinois River including a 3-mile reach of the Fox River near the confluence with the Illinois...
-
The layered mafic and ultramafic Stillwater Complex in southwest Montana is known for its platinum-group element (PGE) production from reef-style mineralization (J-M Reef) in the Lower Banded...
-
Air temperature and relative humidity (T/RH) sensors (Onset Computer Corp. model U23-002) were measured from June 2015 to August 2016 at 100-m elevation intervals, from ~600 to ~1000 m, along a...
-
The American Tunnel, the Black Hawk mine, the Gold King mine, the Mogul mine, and the Red and Bonita mine are located in the Cement Creek watershed, tributary to the upper Animas River near...
-
Paleo-water depth is an important component of modeling surface temperatures through time. Paleo-water depth values represent the elevation of the sediment-water interface relative to global mean...
-
Floodplain inundation is believed to be the dominant physical driver of an array of ecosystem patterns and processes in the Upper Mississippi River System (UMRS), which comprises the Upper...
-
A 3D petroleum systems model requires that the temperature at the sediment surface be defined at each geological time step. Generally, surface temperature can be modeled from paleo-elevation or...
