BOTTOM PHOTOGRAPHY CRUISE, 21-23 JULY, 1952

Abstract

Twenty successful bottom photographs were taken in the lower Chesapeake Bay and adjacent shelf area. These are included in the report along with the Sacchi disc reading, depth measurements, description of the photograph, and information form the core taken nearest the location of photograph. None of the photographs show any evidence of plant life on the bottom. One fish, one worm, one star fish, a track, and numerous shells and shell fragments are the only clear evidence of animal life. The bottom appears to be monotonously flat with only a few photographs showing ripple marks or slight undulation of the bottom. The inorganic bottom material appears to be of sand size or smaller. Six of the photographs are reproduced in stereoptic form.
