PRECISION SOUND VELOCITY PROFILES IN THE OCEAN. VOLUME III. 31 HOURS IN THE TONGUE OF THE OCEAN: SOUND SPEED, TEMPERATURE, ETC. (MARCH 1965).

Abstract

The report covers a 31-hour anchor station in the Tongue of the Ocean, in extremely calm weather. 34 consecutive, detailed, high-precision profiles and their 10, 20 and 31-hour envelopes are presented for both sound speed and temperature, from the sea surface to the bottom; and the graphs showing the gradual changes of constant sound speed and isotherm depths. The sound speed and temperature structure is found to be relatively stable, as in the open ocean. Small, rapid variations abound in the thermocline region; a slight slow rise in deep isotherms occurs, but no tidal effects can be seen. The ship's motions at anchor are described: a composite of diurnal east-west and semidiurnal north-south oscillations. Results of a derivation of salinity from sound speed - temperature - depth data are shown to be in good agreement with published data. (Author)
