NOT YET READY... Airborne electromagnetic (AEM) surveys from the Tallahatchie River near Shellmound, Mississippi
Airborne frequency domain electromagnetic (AEM) data were acquired in a grid pattern consisting of many west-east oriented survey lines over the Tallahatchie River during November 2018. Data were collected by members of the U.S. Geological Survey, Crustal Geophysics and Geochemistry Science Center Group, and CGG. AEM data acquired in Leflore County, Mississippi, were collected to char
Towed transient electromagnetic (tTEM) surveys adjacent to the Tallahatchie River near Shellmound, Mississippi
Towed transient electromagnetic (tTEM) data were acquired adjacent to the Tallahatchie River during March 2018. During the survey, approximately 35 line-kilometers were collected in the Shellmound, Mississippi study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, and the Aarhus University HydroGeophysics Group. FloaTEM data acquired near the
Hyperspectral and RGB image data used to map salmon spawning locations on the American River, California, November 5-7, 2018
An unmanned aerial system (UAS) was used to acquire red/green/blue (RGB) and hyperspectral image data from the American River in California November 5-7, 2018, to support research on remote sensing of rivers, specifically mapping salmon spawning locations (redds) as part of an overall salmon habitat assessment program. The RGB images were acquired uisng a DJI MAtrice 210 equ
Salmon spawning locations (redds) mapped in the field along the American River, California, November 5-7, 2018
This data release includes images and field measurements used to map salmon spawning locations along the American River near Sacramento, California, via remote sensing; the data were collected November 5-7, 2018. The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from various types of remotely sens
Floating transient electromagnetic (FloaTEM) surveys in the Tallahatchie River near Shellmound, Mississippi
Floating transient electromagnetic (FloaTEM) data were acquired on the Tallahatchie River during October 2018. During the survey, approximately 18.3 line-kilometers were collected in the Shellmound, Mississippi study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, Lower-Mississippi Gulf Science Center and the Aarhus University HydroGeophysic
Field measurements of water depth from the American River, California, November 5-7, 2018
Field measurements of water depth were acquired from a reach of the upper American River in California, November 5-7, 2018, to support research on mapping salmon spawning locations (redds) via remote sensing. The depth measurements included in this data release were obtained by wading the shallow channel margins with RTK GPS receivers and measuring water surface elevations along the wat
Field spectra from salmon spawning locations on the American River, California, November 5-7, 2018
This child data release includes field spectra obtained as part of a study focused on mapping salmon spawning locations along the American River near Sacramento, California, via remote sensing; the data were collected November 5-7, 2018. The purpose of this study was to develop and test a spectrally based technique for identifying salmon spawning locations, known as redds, from vario
Floating and Towed Transient Electromagnetic Surveys used to Characterized hydrogeology underlying Rivers and Estuaries: March to December 2018
Surface and water-borne geophysical methods can provide information for the characterization of the subsurface structure of the earth for aquifer investigations. Floating and towed transient electromagnetic (FloaTEM and tTEM) surveys provide resistivity soundings of the subsurface, which can be related to lithology and hydrogeology. In the TEM method, electrical current is cycled through
Floating transient electromagnetic (FloaTEM) surveys in the Rainbow Reservoir near Windsor, Connecticut
Floating transient electromagnetic (FloaTEM) data were acquired on the Rainbow Reservoir during November 2018. During the survey, approximately 12 line-kilometers were collected in the Rainbow Reservoir, near Windsor, Connecticut study area. Data were collected by members of the U.S. Geological Survey, Hydrogeophysics Branch, and New England Water Science Center. FloaTEM data acquir
Floating transient electromagnetic (FloaTEM) surveys in the Delaware River near Barryville, New York
Floating transient electromagnetic (FloaTEM) data were acquired on the Upper Delaware River during December 2018. During the survey, approximately 10 line-kilometers were collected in the Upper Delaware River, near USGS boring 12008-14 (https://webapps.usgs.gov/GeoLogLocator/#!/search) near Barryville, New York study area. Data...
Floating transient electromagnetic (FloaTEM) surveys in the Eel River near Falmouth, Massachusetts

Data used to model and map pH and redox conditions in the Northern Atlantic Coastal Plain aquifer system, eastern USA
Data used to model and map pH and redox conditions in groundwater in the Northern Atlantic Coastal Plain aquifer system, eastern USA, are documented in this data release. The models use as input data measurements of pH and dissolved oxygen concentrations at about 3000 to 5000 wells, which were compiled primarily from U.S. Geological Survey and U.S. Environmental Protection Agency databases....
