The body of a 61-year-old diver has been recovered off the Cork coast; another diver died earlier after getting into difficulty.
The second body was found by a team of local divers close to a wreck site this afternoon.
The air and sea search operation has now been stood down.
The two men, understood to be English, were diving on a wreck off Castlehaven, near Glandore, when the alarm was raised at 9.40am.
They were members of a charter party on board a local boat, Wave Chieftain, which has since come ashore at Union Hall.
One diver, 66, was pulled unconscious from the water, and airlifted to Cork University Hospital where he later died.
The Valentia coastguard co-ordinated the search operation assisted by a rescue helicopter from Waterford, Baltimore lifeboat and coastguard inshore crew.
Local divers had also joined the search operation.
The men were diving on the wreck of a German submarine which was scuttled in 1945.
The submarine is a U-260 and lies in waters up to 45 metres deep.
Four rescued in two separate incidents
A young man is recovering in hospital following an incident off the south Wexford coast.
It is understood he got into difficulties while swimming near Duncannon shortly after 7pm.
He was taken to Waterford Regional Hospital for treatment.
Gardaí say their investigation into the incident is ongoing.
Separately, three women were rescued by Wicklow lifeboat after they were stranded on Silver Strand beach, 4km south of Wicklow town.
Two of the women were taken to hospital by coastguard helicopter and ambulance.
All three were suffering the effects of hypothermia.
The women had become stranded after being trapped by the incoming tide and had spent some time in the water.
