Abstract
ON a recent Atlantic cruise of the USNS Kane, 1,540 exposures of the sea bed were obtained at 77 stations (Fig. 1). The Alpine multi-exposure camera system that was used consisted of a 35 mm camera fitted with a 33 mm f/11 Hopkins water corrected lens actuated by a bottom contact switch. At a typical station, twenty contacts would be made in the course of an hour, at locations varying with the drift of the ship.
