It's hoped better weather conditions off the Mayo coast will help in the search for the missing Dublin crewmen of Rescue 116.
Divers and underwater cameras are being used around Blackrock as efforts continue to locate the bodies of winchmen Ciaran Smith and Paul Ormsby, who have been missing since the rescue helicopter crashed on March 14th.
Yesterday, volunteers resumed their efforts to located the remains of the two men, who were both on board the Dublin-based coastguard helicopter on the night it went down.
The bodies of Captain Dara Fitzpatrick and Captain Mark Duffy were recovered in the days following the accident but the remains of Ciaran Smith and Paul Ormsby have never been located.
During the week, sonar surveys of the waters around Blackrock were carried out and the data gathered during these investigations will be used by the Marine Institute to examine a number of areas beneath the sea surface.
This phase of the operation will see specialist underwater cameras deployed to examine areas of interest.
