#DIVING - Deep sea diver Sean McGahern is currently attempting the world record for cold water open sea diving in Malta.

The Times of Malta reports that McGahern - who was born in England but raised in Ireland before moving to Malta 17 years ago - entered the water at the Starfish Diving School before midnight last night, hoping to break the standing record of 11 hours and 46 minutes.

His previous attempt at the record was ended little more than an hour short of the record due to bad weather, but today's clear forecast has buoyed his confidence.

McGahern plans to pass the time by cleaning the seabed, assisted by a team of 16 safety divers, but he also intended to catch some sleep below the depths.

“I’ve slept underwater before," he said. "it’s not as difficult as you might think.”

McGahern, who previously held the warm water open sea dive record, is undertaking the challenge for Dar tal-Providenza, a home for the disabled on the Mediterranean island.

#SURFING - The second Billabong Tow-In Surf Session will not sadly run this year, following the end of the four-month waiting period yesterday.

Organisers decided to postpone the invitation-only event till next winter after conditions off Mullaghmore Head in Co Sligo failed to reach the minimum height requirement, as Magicseaweed reports.

“We’ve had a few swells that have come close,” said contest organiser Paul O’Kane of the Irish Surf Rescue Club. “However we set the standard incredibly high with the first event and were determined to only hold the event if the conditions were as good as that, if not better.”

Magicseaweed’s Ben Freeston concurred, saying that “the conditions needed for Mullaghmore to show it’s real face are so specific you might only see them a handful of times in the best years.

“This year we have had four or five swells that were big enough to be interesting, but not quite competition standard.”

The inaugural session was organised in an effort to dispel the myth that tow-in surfing, where surfers are towed by jetski to bigger offshore waves, is an irresponsible activity.

Last year's contest was also immortalised in an upcoming documentary from Mully Productions.

#SURFING - Conor Conlon of CMP has produced this wonderful video of top professional surfers taking on the Atlantic swells of the west coast this winter.

Setting up his gear on the shore during a window of clean swell, Conlon captured the likes of Aaron Dees, Conor Maguire, Easkey Britton and newly signed Ripcurl rider Noah Cohen catching the waves (more photos and video HERE).

#MARINE WILDLIFE - TED have posted video of the Irish Whale and Dolphin Group's Dr Simon Berrow giving a talk on the biggest fish in Ireland's waters, the mysterious basking shark.

The second largest fish in the world, basking sharks are almost extinct, and we know almost nothing about them.

But despite their huge size, we do know that they are among the friendlies of Ireland's marine wildlife.

Recorded at the TEDxDublin event at Dublin's Science Gallery in December 2010, the video above shows Dr Berrow describing the fascinating creature (known as the 'Great Fish of the Sun' in Irish) and the surprisingly low-tech methods he's employing in learning all he can to save them.

#KITESURFING - Dublin kitesurfing pro Ross Harte takes our breath away with this video shot from the top of his 12-metre kite, via WorldIrish.

The 30 knot winds are clearly no problem for this daredevil as he catches some big air from the blue surf.

#SURFING - One of Germany's top surfers was in Ireland last week to sample some of Ireland's biggest waves, InsideIreland.ie reports.

Sebastian Steudtner was in Sligo to films a series of online views for Tourism Ireland in Frankfurt to pique the interest of German surfers and holidaymakers.

As well as mountain biking at Knocknarea and Union Woods, Steudtner took on the monster swells at Mullaghmore Head - made popular among the world's big wave surfers by the Tow-In Surf Session that's now in its second year.

The 'teaser' videos for a larger TV and online project will be premiered next week at the Berlin International Film Festival before hitting the web later in spring.

Kristina Gauges of Tourism Ireland said: "This is a fantastic opportunity to showcase the world-class surfing and adventure product available in this part of Ireland to a niche audience in Germany."

#NEWS UPDATE - The search is set to resume again this morning for the three fishermen not yet recovered after their trawler sank off West Cork last Sunday.

Skipper Michael Hayes and Egyptian crewmen Saied Ali Eldin and Wael Mohammed have been missing since the fishing vessel Tit Bonhomme ran aground and went down in rough seas near Adam's Rock, at the mouth of Glandore Harbour.

Only one of the six-person crew, 43-year-old Abdul Mohammed, is confirmed alive after he was able to reach the shore immediately following the incident.

As previously reported on Afloat.ie, Garda divers retrieved the body of Attia Shaban (26) on Thursday morning, followed in the afternoon by that of Kevin Kershaw (21).

Yesterday the search was expanded to cover an 18-mile radius after a dive at the wreck site was unsuccessful, according to The Irish Times.

Divers from the Garda and Naval Service will continue to focus on the wreck today, helped by favourable weather conditions, while volunteers join in the wider search of the coastline.

It emerged on Friday that that boat's aluminium wheelhouse sheared off in the rough seas that followed for three days after it ran aground.

RTÉ News has video of the search operation in progress HERE.

#DUBLIN BAY NEWS - Dublin City Councillors have unanimously rejected controversial plans for flood defences in Clontarf.

As previously reported on Afloat.ie, councillors were set to vote last night on whether to give the green light to the scheme, which has faced strong opposition from local residents and business owners.

The flood barrier would have involved the construction of mounds or walls up to and above 7ft high along the Clontarf promenade.

However, following a vote last night, a redesigned proposal was rejected by the council, with officials admitting to The Irish Times that the public consultation process "didn't work".

Labour councillor Jane Horgan Jones said that it was now up to council officials and the local community to develop an acceptable plan to protect Clontarf from flooding in the future.

"However this is done, it must not be at the cost of destroying a beautiful, free and natural amenity that has been used by generations of Dubliners, from within and outside Clontarf, for many years,” she said.
