Roger Dadds, 66, from Plymouth, died last Saturday, 26 March after making a rapid ascent from a depth of about 60m while on a club dive on the WW2 German submarine U-1063, six miles off Salcombe.
When an emergency call was put out from the dive boat, a helicopter from the frigate HMS Albans, which was close by, transferred him for initial treatment aboard the ship.
A Coastguard helicopter ferried the diver from there to Dorchester Hospital, where it was confirmed that he had died having never regained consciousness.
Dadds, a prominent member of the BSAC’s Plymouth Sound branch, was immensely experienced, having carried out more than 4000 dives over 35 years.
James Irvine, 42, from Glenrothes, went missing in the Firth of Forth’s Largo Bay last Thursday, 24 March.
He was reported to have been diving for scallops and to have surfaced from a dive in about six metres of water to ask for some more weight, before redescending.
When he did not reappear, the crew of his chartered boat made an emergency call and searches were carried out by Kinghorn Lifeboat, a Royal Navy helicopter and a Coastguard shore team.
The diver’s body was located by police divers.
