The report contains charts of Cruise 251 of the ATLANTIS in the North Atlantic Ocean with special surveys on the Blake Plateau. There are 26 charts plotted on a Mercator Projection (scale 1 degree longitude equals 4 inches) showing the track of the entire cruise. All types of observations made during the cruise are noted by suitable symbols or legends along the ship's track. The location of special observations and surveys are shown on Chart I. 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. All soundings are based on a sound velocity of 800 fathoms/second and are corrected for only depth-of-transducer.
