Abstract : The report describes the investigation of the sea floor in the vicinity of Wilmington submarine canyon (38 deg 00 min N to 38 deg 35 min N Lat.; 72 deg 35 min W to 73 deg 40 min W Long.) by means of underwater photography. The techniques of both equipment operation and of interpretation are detailed. More than 1200 photographs were obtained from a net of 54 stations on the continental shelf, slope and upper continental rise in the region encompassing the Wilmington submarine canyon. These photographs, linked to precise navigation, enable assessment of the areal distribution of several sedimentary attributes, notably the texture of bottom sediments, the patterns of recent current activity (neocurrents) and movement of materials, and the role of benthic organisms in modifying bottom sediments.
