OCEANOGRAPHIC SURVEY OF THE GULF OF MEXICO
1953
Adams, Richard M.
Reports are presented of the 3 cruises of the Alaska for the collection of oceanographic and meteorological data. The first cruise was terminated upon the loss of a hydrographic cable. The second cruise covered about 2160 mi. No hydrographic casts were made below 1200 m. Thirty-four stations were occupied, of which 11 were in the water deeper than 1000 fathoms. Sixty-six bathy-thermographic observations were made, 2 on each deep station and the others at 2-hr intervals between stations. Wet- and dry-bulb temperature readings were made at 3 levels at 6-hr intervals throughout the cruise. During the third cruise only 29 of the 55 planned stations were occupied successfully. In addition to hydrographic and bathythermograph casts, sling psychrometer readings were taken at 3 levels and wind, cloud, and other auxiliary data were taken at 6-hr intervals. A short hydrographic survey was made of Mobile Bay, Ala. to acquire the physical and chemical data necessary to determine the circulation and tidal flushing within the bay. The processing of data was completed for the first 5 Alaska cruises in the Gulf. A study is under way to determine a level of no motion in the Gulf. Figures are included for the sea surface isotherns for the first 5 Alaska cruises as well as temperature-depth sections from the sea surface down to 1000 m of the first 3 Alaska cruises.
