The report contains charts of CHAIN Cruise 57 in the North Atlantic Ocean. Sixty-two charts plotted on a Mercator Projection (scale 1 degree Longitude equals 4 inches) show the track of the entire cruise. The Precision Graphic Recorder recorded echo soundings, photographed and reduced, are mounted on the facing page for each track chart. Each type of observation made is noted by a suitable symbol in the chart legend and is shown on Index Charts I through VII. The report also includes the summaries of continuous daily observations and stations occupied. Soundings read at each break in slope are shown on the ship's track. (Author)
