We need a heavy technology discussion on what radar can do about peering through 1000 feet of water to map the undersea.....

I don't think it can, radar depends on reflection...

Mapping the Seafloor from Outer Space

"The time it takes the energy to return to the satellite is used to measure the distance to the sea surface very precisely (within accuracies of less than an inch!)"

According to this link, and depending on the effects of water temperature and surface currents, a seamount of 1000 feet elevation above the surrounding ocean floor would be reflected in an increase of one foot of the ocean's surface. Don't ask me how they account for the motion in ocean's surface motion unless they take the mean time of the reflected beam after repeated passes of the satellite.

From time to time, I’ll post or ping on noteworthy articles about politics, foreign and military affairs. FReepmail me if you want on or off my list.

If you don't like military and technology pings, forget it. I apologize. Otherwise, there are some very interesting links and comments.
