Abstract : The report contains a summary by the Chief Scientists for each of their legs and charts for R/V CHAIN Cruise 82 in the North Atlantic Ocean and Mediterranean Sea with a major survey on the mid-Atlantic Ridge. There are 180 charts plotted on a Mercator Projection (scale 1 longitude equals 4 inches) showing the track of the entire cruise except during 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. Chart III shows special observations made during the mid-Atlantic survey. Also included are total intensity magnetic field measurements (in gammas) which are shown along track opposite the bathymetry. There are 11 pages listing information gathered at each of the 60 study locations. Soundings are read at each break in slope and every 10 minutes. Soundings are based on a sound velocity of 800 fathoms/second and are corrected only for the depth of ship's transducer. (Author)
