A local community in eastern Co Mayo rallied to attempt to save as many as 13 common dolphins that live-stranded near Blacksod on Friday (13 August).

As Mayo IWDG’s Facebook reports, the family group comprising 13 dolphins — mainly mothers and calves with a large male — stranded at Tarmon Beach with the tide dropping.

Sadly three of the dolphins died before they could be helped, but the rest responded to being cooled with buckets of seawater by local volunteers assisting the area’s Irish Whale and Dolphin Group (IWDG) members.

As the tide was still dropping for over an hour, it was quickly decided to move the dolphins 2km by road to the slipway at Blacksod where they could be more easily immersed and cared for.

The local IWDG team used their new wheeled dolphin stretcher to transport the larger marine wildlife to a horse box, while the juveniles were carried in beach towels.

Once carefully released back into the water, all were seen to swim quickly and without obvious distress, and by 9pm the pod had left the area.

“Tarmon and the surrounding beaches on the east side of the Mullet Peninsula are notorious for common dolphins live-stranding due to the topography of the beaches,” Mayo IWDG said.

“The beaches are large flat expanses so during spring tides especially, the water can level can drop uniformly and recede up to 1km in parts. Common dolphins being an offshore dolphin species often get caught out on such difficult-to-navigate shallow terrain.

“When a dolphin live-strands it puts immense pressure on their bodies. They can become very disorientated and have muscle spasms from the stranding event making it difficult to swim, which is why this group were given recovery time at Blacksod before being released.

“Thanks again to everyone who helped out today; it was so humbling to see everyone work together to get this pod back to the sea.”

Elsewhere, the IWDG reports on two separate strandings of Sowerby’s beaked whales in Co Galway. The first was found washed up on Inisbofin at the end of the week while the second was reported yesterday (Saturday 14 August) across the water in Cleggan.

Commenting on the former report, the IWDG said: “Beaked whales are not stranded that frequently but this individual had evidence of rope marks on its body.

“As [they are] an offshore deep-diving species we don’t expect beaked whales to get entangled in fishing gear or interact with offshore activity.

“Maybe these rope marks were not from fishing but some other source. Hard to tell, but without a full post-mortem examination the cause of death will remain speculative.”

A Sowerby’s beaked whale — of a marine wildlife species rarely sighted in Irish waters — has died after getting into distress in Wicklow Harbour, as The Irish Times reports.

According to the Irish Whale and Dolphin Group (IWDG), the male whale stranded near Wicklow Sailing Club after losing its bearings yesterday morning, Saturday 4 July.

Sowerby’s beaked whales are one of four out of 22 beaked whale species known to be in Irish waters. They normally inhabit deep waters below 200 metres in the North Atlantic, and are rarely seen by humans.

“From the outset it appeared to be in poor health, appearing disorientated and having difficulty moving. Therefore, it would not have been a candidate for refloating,” the IWDG said in a statement on Facebook.

“Euthanasia is also extremely difficult in these circumstances due to the large size of the animal as well as public safety concerns.”

The whale will be recovered for a full post-mortem to try and “to find out more about the life of these rare and enigmatic whales”, said IWDG chief executive Dr Simon Berrow.

Ten months ago a Sowerby’s beaked whale stranded on a beach near Helvick Head in Co Waterford. While it was refloated twice by local lifeboat volunteers, it was thought unlikely to survive.

Concerns remain for the health of a rare beaked whale refloated from a Co Waterford beach at the weekend, as The Irish Times reports.

The Sowerby’s beaked whale stranded near Helvick Head on Friday (30 August) and was twice returned to the open sea by the local RNLI lifeboat crew.

The incident marks the fourth stranding this year around the coast — and the only live stranding — of a deep water marine wildlife species that’s historically been rare in Irish inshore waters, with only 25 confirmed since records began.

Its fate is currently unknown, but Irish Whale and Dolphin Group (IWDG) strandings officer Mick O’Connell suggests the situation doesn’t look good.

“Sowerbys usually live in much deeper water 300kms off the west coast — that makes me think it’s unlikely it will survive — it may be sick, but it’s got as good a chance to survive as it could because everything was done locally to get it back out to sea,” he said.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

RV Tom Crean Specification Overview

  • Length Overall: 52.8 m
  • Beam 14m
  • Draft 5.2M 

Power

  • Main Propulsion Motor 2000 kw
  • Bow Thruster 780 kw
  • Tunnel thruster 400 kw

Other

  • Endurance  21 Days
  • Range of 8,000 nautical miles
  • DP1 Dynamic Positioning
  • Capacity for 3 x 20ft Containers

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
