This iReport is part of an assignment:
Malaysia Airlines Flight 370
Flight MH 370
The range of 2 miles for the TPL is probably for a pinger and TPL in a homogenous water body. The sound would attenuate according to the square of the distance from the source. With inhomogeneous water characteristics the wavefront may become linear (not circular) and travel much further without major loss of intensity. Such phenomena are known as thermoclines.
Let me know if you would like some graphics. If you find my comments interesting I suggest that you run them past people involved in deploying underwater instrumentation (current meters). Woods Hole would be the perfect place to start.
