Sonar? I did not think microwaves moved very well through sea water.
I think it's sonar backed up by spot checks using other methods.
Picky quibble I admit. The sea floor has indeed been mapped out,
at least well enough to spot a km sized crater.

The preceding are my opinions alone and have nothing
whatever to do with my employer. I don't even know what my
employer thinks. I'm not even real sure who the CEO is.
