A Report on the Processing of Aircraft Expendable Bathythermograph Data.

Abstract

The temperature profiles obtained by Aircraft Expendable Bathythermographs (AXBT) on a flight from Oahu to Kodiak on 18 March, 1970, are presented together with the temperature section and the sound velocity section obtained by calculation using probable salinity values as derived from other sources. The resulting near-surface, short-range sound transmission conditions are described and their relative importance in the long-range transmission of sound is discussed. A detailed description is provided of the method which has been developed to plot temperature profiles from the magnetic tape record of AXBT drops with output accuracy of one-tenth degree Celsius at each four meters of depth. The increase in accuracy and the savings in manpower and time are significant. The quickly-achieved graphic display of the temperature profile permits ready analysis of the AXBT record. (Author)
