Good -- I am glad to see that you understand that this is the distance down to the seafloor and back!

So the water depth would be only half of 3600 meters

Here is the water depth calculation:

So the water depth in this example is 1800 meters (over 1 mile deep)

The easiest way to do this problem (determine the water depth) is to measure the two-way traveltime from the echo profiler data and multiply this number by 750 meters per second
