SOFAR Channel Axial Sound Speed and Depth in the Atlantic Ocean.

reportActive / Technical Report | Accession Number: AD0778030 | Need Help?

Abstract:

Axial sound speed and depths of the SOFAR channels in the North and South Atlantic have been estimated and the seasonal variations that affect SOFAR propagation examined. The estimates are derived from applying averaging techniques to archived oceanographic data. The computed values appear to agree within one part in a 1000 with the measured data from long-range propagation experiments. A more accurate sound speed mapping method is recommended, as is the incorporation of measured values of speed and depth in any SOFAR computer program. Author
