On the underwater GPS thing... At least 20 years ago a college professor contacted me and wanted to map the dive park with a GPS. I explained to her that they didn't work underwater and that with selective availability on, the positional information would be worthless. I had a GPS unit back then and had mapped the readings from a fixed location over a period of one hour and they were all over the place.

She decided that we would release tethered air-filled bottles from various points in the dive park and she would row over to them and take a reading. As you can imagine, the results placed objects all over the place with several of them located up high and dry on shore!
