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.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.

Reports in this series present raw field data and analytical results with limited or no interpretation by DGGS staff or project collaborators. The reports and accompanying data have been evaluated by project staff for general readability and logical consistency but have not undergone technical peer review. Repeat readings were made for data quality. The data were examined and filtered to remove erroneous locations or readings. The accompanying report provides additional detail.Data originate from one company using the same contract specifications for all data. The originating coordinate system was retained for all publication products.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.Station coordinates were positioned using a real-time or post-processed corrected differential GPS.Not applicableData 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.2016Universal Transverse Mercator60.999600-1470500000.0000000coordinate pair.00000001.00000001MetersWorld Geodetic System of 1984WGS 846378137298.257223563000025ascii_dataASCII format line data, other ASCII dataClark Jorgensenascii_datadatabases_geosoftGeosoft format database of line data, other Geosoft format databasesClark Jorgensendatabases_geosoftdocumentsProject and field reports, survey background information, gridded data explanations, other supporting documentationClark Jorgensen and Alaska Division of Geological & Geophysical Surveys (DGGS)documentsgrids_geosoftGeosoft-format binary grids, these grids can be viewed in ESRI ArcMap using a free plugin from Geosoft or using the free viewer available from GeosoftClark Jorgensen and Alaska Division of Geological & Geophysical Surveys (DGGS)grids_geosoftimages_registeredGeoTiff format images of all gridded dataAlaska Division of Geological & Geophysical Surveys (DGGS)images_registeredkmzKeyhole markup language (kml) kmz archive files of project data.
