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

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...
