The Goldstream Valley, located in Fairbanks, Alaska, is a semi-urban arctic watershed targeted for multidisciplinary investigations of interactions between permafrost, groundwater, surface hydrology, and biogeochemical cycles to understand the release of methane gas from degrading permafrost. To support concurrent research, Alaska Division of Geological & Geophysical Surveys (DGGS) staff collected gravity measurements from 105 stations throughout the Goldstream Valley during 2017 and 2018 (fig. 1). These stations were collected to help determine the depth of fill in the Goldstream Valley. Bouguer anomaly maps were created of the study area. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30473.

This data set is complete and includes files that contain both raw and processed gravity data as well as corresponding locational data for the entire survey area. Data originate from one company using the same contract specifications for all data. The originating coordinate system was retained for all publication products. This lineage was generated by the FGDC CSDGM to 19139 transformation Data collection, processing, reporting - CSAMT data were acquired throughout the study area using a Stratagem EH4 standard transmitter electrical resistivity imaging system from August 9th to 11th, 2016. Electrodes were 50 meters apart. Electrode dipoles and magnetic coils were oriented east-west and north-south. Stations were located with a WAAS enabled L1 handheld GPS units. Data were evaluated for quality. In some cases, the natural source signals were low amplitude and often poor quality. All poor time series were deleted from the data. Using IMAGEM software, one-dimensional inversion models were created for east-west and north-south orientations. 2016-01-01T00:00:00 otherRestrictions Metadata Use Constraints: If the user has modified the data in any way they are obligated to describe the types of modifications they have performed in the supporting metadata file.
