National Geophysical Data Retrieval and Integration Project

This project helped to streamline the workflow from geophysical data acquisition to data distribution, and additionally provided user support for integration and interpretation of these complex data sets. There were four main objectives: 1) contracting geophysical surveys, 2) converting data from analog to digital format, 3) archiving, retrieving, and integrating geophysical data, and 4) ...

Alaska Geophysical Survey Interpretation

Available geophysical data for Alaska have not been fully exploited. Project objectives were to conduct systematic analysis of existing gravity, aeromagnetic and airborne electromagnetic data to map geologic trends, structural geologic and tectonic patterns, and identify key lithologies for direct integration with geologic framework and mineral potential studies.
