#MARINE WILDLIFE - Ireland's first humpback whale of the year has been spotted off the Wexford coast.

The sighting was made yesterday by whale-watchers among a pod of fin whales some three miles south of Hook Head, according to TheJournal.ie.

The Irish Whale and Dolphin Group (IWDG) has also confirmed that the humpback is a new sighting in Irish waters, and has been designated the reference HBIRL18.

#MARINE WILDLIFE - A "feeding frenzy" involving a pod of fin whales was spotted off Hook Head in Co Wexford last week, The Irish Times reports.

And according to Andrew Malcolm of the Irish Whale and Dolphin Group (IWDG), two of the whales were in the same location almost exactly a year ago.

Malcolm, who was with a group on board the Rebecca C, used photographs of the whale's dorsal fins to compare records for the confirmation.

The pod of six fin whales was seen feeding some 3km southeast of Hook Head, attracted by the herring spawning grounds in the area.

More than 30 other cetaceans, including common dolphins, porpoises and a minke whale, were sighted on the trip.

The Irish Whale and Dolphin Group (IWDG) has said that evidence suggests a pod of three bottlenose dolphins is living on the east coast of Ireland.
According to RTÉ News, the organisation as validated close to 200 sightings of the dolphins - one of whom was spotted off Co Down in October 2010 - along the Dublin and Wicklow coastline in the last year.
The IWDG's Páraig Whooley says that further analysis of theor movements show that they rarely travel north beyond Dalkey Island or south of Wicklow town, ind
icating a core range of 21 miles (33km).
"Remarkably, they seem to split their time evenly between their Dublin and Wicklow hotspots, thus making them extremely easy to locate, observe and photograph," he adds.
"In fact... the best way to find them other than checking this site, is probably to jump on a DART train in Dun Laoghaire bound for Greystones (or visa versa), making sure to look out the correct window."
While well known for being "boisterous, interactive and gregarious", bottlenose dolphins are also "indescriminate killers of porpoises and other dolphin species, with well-documented cases of infanticide".
Neither are they to be taken lightly by swimmers, with "a case load in Ireland of attacks on swimmers leading to serious injury, and at least one overseas case of [a bottlenose] killing a swimmer.
"It's nice to be able to boast of an apex predator lurking so close to the capital," adds Whooley.

The Irish Independent reports that some 100 bottlenose dolphins have made a new home off the Donegal coast in the past week.
The pod of bottlenoses - a rare treat in Irish waters compared to the near ubiquitous common dolphin - has been spoted by boaters and wildlife enthusiasts in the inner Donegal Bay, between Rossnowlagh Beach and Doorin Head.
Patrick Lane of the Irish Whale and Dolphin Group said the bottlenose often swims closer to the shore than its more common counterparts, making it much easier for people on shore to catch a glimpse.

The Irish Whale and Dolphin Group (IWDG) spotted killer whales off the coast of county Kerry during an offshore survey last weekend.  The killer whales crossed within two metres of the bow of the research vessel, others swam just beneath the surface keeping a parallel course with the surveyors.

The sighting of an adult pod is a rare encounter in Irish waters. 2010 has been a good year for killer whale sightings here with 14 validated records to date. 

IWDG surveyors were able to photograph the whales and have sent the findings to expert researchers  in the University of Aberdeen. It is understood these are new animals, not previously catalogued during the past few years of surveying killer whales in the North East Atlantic.

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
