Floating Transient Electromagnetic Survey Data from the Columbia River near Hanford, WA
This data release contains motorboat-towed floating transient electromagnetic data collected from the Columbia River near Hanford WA. Data were collected using a ~16 foot (4.9 meters) outboard motorboat during two field campaigns: July 2021 and April 2022. In total, several hundred linear kilometers of data were collected from a reach of the Columbia that extends from approximately Vernita Bridge to Richland, WA with some additional data collected in the Horn area north of White Bluffs in April 2022.
An Aarhus Geoinstruments FloaTEM system was used to collect these data. The depth of investigation of the FloaTEM system is variable but ranged from approximately 50 to 100 meters. Previously collected high-resolution bathymetric data and observed specific conductance of the water column were used to constrain water depth and resistivity in the processing and interpretation of results.
