摘要

This report contains charts of Cruise 44 of the CHAIN in the North Atlantic Ocean. There are 40 charts plotted on a Mercator Projection (scale 1° 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 and II. Charts III, IV, V show special observations made over the Mid-Atlantic Ridge. There are 12 pages showing continuous daily observations, including types of information gathered at each of the stations made. 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.
