I put those search terms in the shipanalysis.com search engine. This catches my eye #1 - the divers and #2 - a decomposed body was also just found in NYC East River.
Look at this:
Body of missing Panhandle fisherman recovered from Gulf
Associated Press
MOBILE, Ala. - A decomposed body recovered from the Gulf of Mexico was identified Saturday as a missing Florida fisherman.
Don Jones, of Pensacola, has been missing since Feb. 23 when his commercial fishing boat, the Sarah B, disappeared during a storm about 45 miles south of Dauphin Island.
His body was recovered Friday from the water about 20 miles southeast of Dauphin Island. The medical examiner says Jones died of hypothermia and drowning.
His crew member, Ida Fitzpatrick, 45, also of Pensacola, was still missing.
The Sarah B was owned by Parker Seafood Co. in Perdido Key west of Pensacola. Company owner Mike Parker said Friday that authorities have told him very little
Another sea worthy boat missing, this would be of a good size, maybe a good terrorist boat.
I didn't find much under 'dead diver', but a google for:
1425 dead divers
was better.
Virgin Islands search and rescue newsletter
On 18th of March, 2003 note that they recovered 3 divers (dead? as I recall), there was no sign of a divers boat or equipment.

On so many of these they are in pdf and I can't do that.
Next, I googled for:
Search and Rescue for Dead Divers
This I want to do again, as I saw several sites for the Search and Rescue Dogs, as well as reports on other groups.
If you can read the reports, I think that you will find other reports on divers, that leave you wondering and maybe reaching for the tin foil.''
