Authorities released the name Wednesday of a government contractor who drowned Monday night while taking part in a nighttime scuba dive in San Diego Bay as part of a Navy marine-mammal program.

Coll Perske, 29, failed to surface as scheduled during an exercise off Naval Air Station Coronado, according to the county Medical Examiner’s Office.

Colleagues pulled him to the surface and tried in vain to resuscitate him. Medics took him to UCSD Medical Center in Hillcrest, where he was pronounced dead shortly after 10 p.m.

Perske, a San Diego resident, was employed by Science Applications International Corporation and was assigned to the Space and Naval Warfare Systems Center Pacific Marine Mammal Program, according to SAIC.

The program, started in the 1950s, trains bottlenose dolphins and sea lions to search for, detect and mark underwater divers or objects.

The cause of the accident was under investigation.
