Geophysical Data Bases at the Atlantic Geoscience Centre

Geophysicists at the Atlantic Geoscience Centre have recently completed a major overhaul and compilation of marine gravity and magnetic data collected off the east coast of Canada, and have enhanced these observations with other information collected over adjacent land and sea areas: aeromagnetic data, land gravity measurements, gravity values derived from satellite altimetry, bathymetry, and depth to basement. The resulting data sets have been organized for efficient handling and storage. Used in conjunction with recently implemented tools for rapid data manipulation and display, the data bases are a valuable resource for scientific research. This paper describes the general procedures followed in implementing the data bases, and presents some sample display products.
