USGS Data Series 355: Oregon Magnetic and Gravity Maps and Data: A Web Site for Distribution of Data

Oregon Magnetic and Gravity Maps and Data: A Web Site for Distribution of Data

By Carter W. Roberts, Robert P. Kucks, and Patricia L. Hill

This web site gives the results of a USGS project to acquire the best available, public-domain, aeromagnetic and gravity data in the United States and merge these data into uniform, composite grids for each State. The results for the State of Oregon are presented here on this site. Files of aeromagnetic and gravity grids and images are available for these States for downloading. In Oregon, 49 magnetic surveys have been knit together to form a single digital grid and map. Also, a complete Bouguer gravity anomaly grid and map was generated from 40,665 gravity station measurements in and adjacent to Oregon. In addition, a map shows the location of the aeromagnetic surveys, color-coded to the survey flight-line spacing. This project was supported by the Mineral Resource Program of the USGS.
