Abstract : The report contains a summary and charts for R/V CHAIN Cruise 61 in the North Atlantic Ocean, Mediterranean and Red Seas. There are 133 charts plotted on a Mercator Projection (1 degree longitude equals 4 inches) showing the track of the entire cruise except for special surveys. All types of observations made during the cruise are noted by suitable symbols or legends along the ship's track. The locations of Special Surveys are shown on Charts I - II - III and IV. Charts V and VI show special observations made in the Hot Brine Region. There are 20 pages listing information gathered at each of the 178 stations made. Soundings are read at equal time intervals, usually every ten minutes, and in some cases at each break in slope. They are written along the ship's track as often as space permits. Soundings are based on a sound velocity of 800 fathoms/second and are corrected only for the depth of transducer. (Author)
