Investigations Conducted by the United Stares Coast Guard during 1933

Abstract

During the Ice‐Patrol season of 1933 the United states Coast Guard Patrol‐Boat General Greene made six cruises in the vicinity of the Grand Banks of Newfoundland, collecting on each cruise, by observation and radio reports, data for the construction of surface isothermal charts of the Grand Banks Region. During this period 25 oceanographic stations were occupied, at each of which temperatures and salinities were measured from the surface down to 1000 meters where the depth permitted. About 100 fathometer‐soundings for which positions and correction‐data are available were taken, chiefly in the rectangle between 46° and 48° north latitude, and between 45° and 48° west longitude.A post‐season northern cruise was made in the waters between Newfoundland and Labrador, and southwestern Greenland between June 26 and July 24, 1933. One hundred and twelve oceanographic stations were taken, most of them being reoccupations of stations taken on the northern cruise in 1931. At these stations temperature‐ and salinity‐measurements extended from the surface down to 2000 or 2500 meters where the depth permitted. Several hundred well‐located fathometer‐soundings were taken for which correction‐data are available. Arsuk Glacier in southwestern Greenland was visited and photographs recording its retreat were made.
