Online_Linkage: http://doi.org/10.14509/30461 Description: Abstract: Gravity data were acquired at 1,175 stations during the period April 13 to May 3, 1982 by EDCON, Inc. using a helicopter-borne inertial surveying system and LaCoste and Romberg G-meters. Of the total number of stations, 1,156 were acquired along one of 19 lines and the remaining 19 stations were control points or gravity bases. The survey is located in southwestern Alaska approximately 325 kilometers west of Anchorage, Alaska. Stations acquired along the 19 lines. In general, gravity stations were spaced approximately 1,600 meters apart along northwest-southeast oriented lines which were spaced 9,500 meters apart. The data, as well as additional metadata, are available from the DGGS website: http://doi.org/10.14509/30461. Purpose: These data were collected to assist the state in assessing the hydrocarbon potential of the Holitna Basin area. The gravity data were intended to be interpreted and integrated with available geoscience data.
