The multibeam surveys were carried out as part of a larger survey of the New York Bight and the Hudson Shelf Valley (Butman and others (1998); Butman (1998); Butman and others (2002); and USGS Studies in the New York Bight). The surveys were carried out using a Simrad EM 1000 sea floor mapping system mounted on the survey vessel Frederick G. Creed. The surveys at sites A; B; C and F were carried out in 1996 and 1998 prior to the Hudson Shelf Valley winter experiment and were used to help locate the instruments in the axis of the valley. Multibeam surveys at sites D and E on the continental shelf were carried out in April 2000 after the instruments were retrieved. Backscatter intensity from a sidescan sonar survey of the New York Bight Apex was used to help place these instruments (see Schwab and others; 2000)., Bottom photographs; videos and sediment samples of the sea floor were obtained on the mooring deployment (RV Oceanus; December 1999) and recovery cruises (RV Endeavor; April 2000) to show the character of the sea floor. These observations were made using the SeaBed Observation and Sampling System (SEABOSS) (Valentine and others (2000) ; Blackwood and Parolski (2002)). SEABOSS is equipped with two video cameras; a still camera; a pressure-depth sensor; and a modified Van Veen sediment grab sampler. At each station; the SEABOSS was lowered to a target elevation about 76 centimeters (30 inches) above the sea floor and the ship allowed to slowly drift; typically for a few hundred meters. As the ship drifted; typically at a knot or less; bottom video was recorded continuously and individual photographs of the sea floor were triggered remotely based on the video available in real time at the surface. Typically 5-50 still photographs were obtained at each station. At 76 centimeters above the bottom; the still photographs show a 76 x 51 centimeter area of the seafloor. At most stations; a single sample of the sediment was obtained using the Van Veen sampler; typically at the end of the transect. At some locations; cobbles and boulders on the seafloor made sampling impossible. The upper 2 cm of the sediment were skimmed from the grab sample and analyzed for texture using the methods outlined in Poppe and others (2000). Additional photographs and videos from these and other stations in the New York Bight may be found in Butman and others (in press). , Purpose: Sediment transport and circulation observations in the vicinity of the Hudson Shelf Valley as part of a program to investigate the transport and fate of sediment and associated contaminants in the coastal waters offshore of the New York - New Jersey metropolitan region.
