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.

Excerpt from Photographic Investigation of Sediment d104ure, Bottom Current Activity, and Benthonic Organisms in the Wilmington Submarine Canyon: U. S. C. G. C. Rockaway-Smithsonian Institution Cruise (Ros), December 1967 Wilmington Canyon originates near the edge of the continental shelf approximately 95 nau tical miles east-southeast Of the mouth of Dela ware Bay. The canyon head may be traced northeastward (landward) to a minimum depth of 45 fathoms, at which point it is incised into the shelf for a distance of about 10 miles (fig. From this point the canyon trends south southwest for nearly 7 miles to an axial depth of 380 fms and then makes a sharp turn to a general southeasterly course. This course is maintained to an axial depth of about 1000 fms, near the base of the continental slope, and is ih terrupted only by an abrupt turn to the east for almost 3 miles at 700 to 780 fms. The canyon trends almost due east across the upper part of the continental rise where it gradually dimin ishes in relief. Beyond the 1300 fms isobath the canyon, which would better be described as a submarine valley because of its low relief, ex tends toward the east-southeast to a depth of about 1800 fms. The gradient of the canyon axis become steeper and the relief increases in the lower rise (1800 - 2500 fms). The canyon trend is almost due south between 1800 and 2000 fms, then becomes generally southeast. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

An ocean bottom survey of an 8 x 30 mile area encompassing portions of the continental shelf and slope northeast of Hudson Canyon has been conducted. Included in the investigation were ocean floor mapping, sub-bottom reflection studies, sediment studies, bottom photography, and near-bottom ocean current and temperature measurements. (Author).
