GFLOW groundwater flow model for the Park Falls Unit of the Chequamegon-Nicolet National Forest, Wisconsin

A GFLOW model was constructed of the Park Falls Unit as part of a larger study of the Chequamegon-Nicolet National Forest. The model supports the goals of the project by providing improved characterization of the groundwater/surface-water system and a tool to evaluate the sensitivity of hydrologic flows and temperature to future climate and land use changes. The purpose of this model and the bigge

Field measurements for characterizing salmon spawning habitat in two restored reaches of the lower Merced River, California

To support an investigation of the effectiveness of a large-scale river restoration project, several types of field data were collected from two gravel-bed reaches of the regulated lower Merced River in California's Central Valley, primarily in the fall of 2016. These data sets were intended to characterize salmon spawning habitat and identify factors influencing spawning site selection. This pa

Hyperspectral image data and multibeam echosounder surveys used for bathymetric mapping of the Kootenai River in northern Idaho, September 26-27, 2017

To support research on remote sensing of rivers, hyperspectral image data and supporting field measurements of water depth obtained with a multibeam echosounder were acquired from a segment of the Kootenai River in northern Idaho, September 26 and 27, 2017. These data sets also facilitate efforts to characterize in-stream habitat for sturgeon, understand and model dispersion processes, and monito

Metal Concentrations of Sediment from 1993-2017 in San Francisco Bay-Delta Estuary (San Pablo Bay and Suisun Bay), CA

Surface sediment samples from the North San Francisco Bay-Delta Estuary were collected monthly at five stations located west of Rio Vista and east of Point Pinole. Sediment was collected near Montezuma Slough, Chips Island, the Concord Naval Weapons Station, Carquinez Strait near Martinez, and San Pablo Bay at water depths ranging from 6.5 to 14.3 meters. Samples were collected coincident with wat

Geophysical data from the unnamed lake at the National Crude Oil Spill Fate and Natural Attenuation Research Site, Bemidji, MN (ver. 3.0, May 2022)

The National Crude Oil Spill Fate and Natural Attenuation Research Site is located near Bemidji, MN, USA. A high-pressure oil pipeline ruptured in 1979 releasing ~1.7 million liters of light crude oil, which sprayed over an area of ~6500 square meters and collected in topographic depressions. Approximately 75% of the spilled oil was recovered. Much of the remainder reached the water table, where i

2016-2017 Geophysical data from the Kuparuk aufeis, North Slope, AK

This release contains geophysical data from the Kuparuk aufeis associated with the manuscript "Seasonal thaw dynamics of an aufeis feature inferred from surface geophysical methods." Data were collected in two campaigns in September 2016 and April 2017 with the purpose of investigating freeze-thaw dynamics below the aufeis feature during maximally frozen and maximally thawed conditions.
