Online_Linkage: https://doi.org/10.14509/30472 Description: Abstract: Pilgrim Hot Springs is in the Seward Peninsula, western Alaska, approximately 60 road miles north of Nome. Pilgrim Hot Springs has reported surface temperatures ranging from 145 degrees F to 160 degrees F (63 degrees C-71 degrees C) (Miller and others, 1973; Motyka and others, 1983). Due to the proximity to a large community, Pilgrim Hot Springs is considered a potential resource for providing power or direct-use heat. As a pilot study to inform ongoing investigation of the subsurface geology of Pilgrim Hot Springs, DGGS staff collected 29 controlled source and natural source audio magnetotelluric (CSAMT) readings to develop resistivity models of the study area. This data release provides Stratogem format raw data and resistivity models and depth slice grids in ASCII text and GeoTIFF format. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30472. Purpose: Due to the proximity to a large community, Pilgrim Hot Springs is considered a potential resource for providing power or direct-use heat. To inform ongoing investigation of the geology of Pilgrim Hot Springs, DGGS staff collected 29 controlled source and natural source audio magnetotelluric (CSAMT) readings to develop resistivity models of the study area. These data were acquired as a pilot study to determine if CSAMT data would provide new insight into the subsurface geology.

In some cases, the natural source signals were low amplitude and often poor quality. All poor time series were deleted from the data. Logical_Consistency_Report: Data originate from one collection effort using the same specifications for all data. The originating coordinate system was retained for all publication products. Completeness_Report: This release provides data directly downloaded from the Stratagem instrument with no editing and the reprocessed data used for modeling and interpretation. IMAGEM software is required to read these data. IMAGEM software and instructions are available from DGGS upon request.

Vertical_Positional_Accuracy: Vertical_Positional_Accuracy_Report: Not applicable Lineage: Process_Step: Process_Description: 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.
