Résumé

The final product of a recent data processing contract issued by the Atlantic Geoscience Centre was a suite of 72 Natural Resource maps published by the Canadian Hydrographic Service representing the most comprehensive published collection of marine gravity and magnetic data on the eastern Canadian continental shelf. Because of the techniques employed, the charts have a style different from that employed on previous charts in the series. The method of preparation of the charts is described together with consideration of the basic limitations of a contour chart used as a source of data. Deficiencies in the data collection and processing and chart preparation techniques are discussed.
