Track Charts, Bathymetry, and Location of Observations

Résumé du livre

This report contains charts of Cruise 51 of CHAIN in the North Atlantic Ocean. There are 22 charts plotted on a Mercator Projection (scale 1 degree longitude equals 4 inches) showing the track of the entire cruise except for the area within 5 miles of Project Sea Spider on the Blake Plateau. All types of observations made during the cruise are noted by suitable symbols or legends and are shown on Index Charts. Soundings are read at equal time intervals, usually every five minutes, and at each break in slope. They are written along the ship's track as often as space permits. (Author).
