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.\nThese 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.\n\n>ascii_data: ASCII format line data, other ASCII data\t\n>documents: Project and field reports, survey background information, gridded data explanations, other supporting documentation\t\n>grids_geosoft: Geosoft-format binary grids, these grids can be viewed in ESRI ArcMap using a free plugin from Geosoft or using the free viewer available from Geosoft\t\n>images_registered: GeoTiff format images of all gridded data\t\n>maps_pdf_format: Printable maps in pdf format\t\n>vector_data: Line path, data contours, and survey boundary in ESRI shapefile (SHP) format, ESRI Geodatabase format, and/or AutoCAD dxf format\n\n\n\n\n\n1982\n\n\nground condition\n\n\ncomplete\nNone planned\n\n\n\n-157.817428\n-154.598616\n62.665410\n60.825744\n\n\n\n\nISO 19115 Topic Category\ngeoscientificInformation\n\n\nAlaska Division of Geological & Geophysical Surveys\nBasins\nEnergy\nExploration\nGeologic\nGeology\nGeophysical Map\nGeophysical Survey\nGeophysics\nGeophysics Search Tag\nGravity\nGravity Survey\nGridded Data\nLine Data\nRemote Sensing\n\n\nAlaska Division of Geological & Geophysical Surveys\nBarometer Mine\nBarometer Mountain\nBasket Creek\nBeaverhouse Hill\nBig Lake\nBig River\nBlack Creek\nBlack Mountains\nBlackwater Creek\nCaribou Snare Creek\nCheeneetnuk River\nChuilnuk River\nCotton Village\nCribby Creek\nDoor Creek\nDoor Mountains\nEightmile Creek\nElutuli Creek\nFuller Creek\nFuller Mountain\nGagaryah River\nHoholitna River\nHolitna River\nHook Creek\nHungry Creek\nInowak Creek\nItulilik Creek\nKatlitna River\nKeefer Creek\nKulukbuk Hills\nKuskokwim River\nKutokbuna Lake\nLime Hills\nLime Village\nMoose Creek\nMoose Village\nMuskeg Creek\nMuskrat Creek\nNunsatuk River\nParks Creek\nRed Devil\nRed Devil Creek\nRed Mountain\nSelatna Mountain\nSelatna River\nShoeleather Creek\nSleetmute\nStink River\nStony River\nSwift River\nTatlawiksuk River\nTaylor Creek\nTishimna Lake\nTitnuk Creek\nTrout Lake\nTundra Lake\nVreeland Creek\nWhy Lake\nWillis Creek\n\n\nThis report, map, and/or dataset is available directly from the State of Alaska, Department of Natural Resources, Division of Geological & Geophysical Surveys (see contact information below).\nAny hard copies or published datasets utilizing these datasets shall clearly indicate their source.
