Figure 4. Sonobuoy station locations in the Bay of Bengal and adjacent areas as revised from 

 Hamilton et al (1974) which contained only Antipode and Circe data. The base chart is from 

 Moore et al (1974); contours are in meters, corrected for sound velocity. Station numbers are 

 adjacent to symbols. Symbols refer to Scripps Institution of Oceanography expeditions. A 

 number of closely-spaced sonobuoys (at a single, numbered station) are represented by a 

 single dot.
