Analyzing the SOFAR Channel

This analysis explores the Sound Fixing and Ranging (SOFAR) channel's characteristics at various geographical locations by utilizing a mid-latitude typical Sound Speed Profile (SSP) diagram. Students will work in pairs to draw the expected SSPs for the Arctic, equator, and shallow water environments. They will also investigate the mechanisms of upward and downward refraction, highlighting how temperature and salinity variations affect sound propagation differently in each scenario. Understanding these processes is crucial for marine acoustics and is applicable in navigation and marine biology studies.

  1. Analyzing the SOFAR Channel . • Question (in groups of 2-3): Using the diagram you have been given containing a typical SSP at mid-latitudes, draw the typical SSP for the following, and explain how (upward/downward) and why refraction would occur at each: • The Arctic • The equator • In shallow water
