Abstract

An exciting new application for multibeam bathymetric surveying is sea floor habitat mapping,in which a geological interpretation of bottom sediments is integrated with biological and oceanographic information. The present area of interest, Browns Bank on the southwestern Scotian Shelf (3), is extensively fished for sea scallops (4) and ground fish. The purpose of this cooperative work between the Geological Survey of Canada (Atlantic), the Canadian Hydrographic Service and the Department of Fisheries and Oceans is to produce sea floor maps of Browns Bank for fisheries habitat management, the commercial fishery, navigation charting, and geological assessment.
