Résumé(disponible en anglais seulement)
Coastal and ocean environments worldwide are coming under increasing pressure from resource development. In some cases, integrated coastal zone management programs have been successfully adopted. However, with the collapse of offshore fisheries and competition among industries for use of the seabed, many maritime countries are recognizing that more data are needed to support the sustainable management of offshore resources. Developments in multibeam mapping technology, in concert with traditional geoscience survey techniques, now provide the capability to image the sea floor in high resolution. Examples from the Canadian Atlantic continental margin are used to demonstrate the application of high-resolution sea floor mapping techniques to develop data bases and maps; these maps are fundamental information for the future management of offshore resources.
