Up to 380 sperm whales are living in deep waters off the Irish coast, a newly published study has found. 

This makes sperm whales “one of the most abundant great whale species” in these waters, expert Dr Simon Berrow says. 

Sperm whales are known for their distinctive echolocation “clicks” which can be heard over many tens of kilometres, and this allows them to be counted.

A survey team from Galway-Mayo Institute of Technology (GMIT) and the Scottish Sea Mammal Research Unit (SMRU) Consulting spent 45 days at sea in harsh weather conditions to conduct the population count.

“With high sea states and towering swell, the study relied purely on being able to detect the distinctive powerful click trains of sperm whales using a streamlined towed hydrophone or underwater microphone array,” Dr Berrow said. 

The results were published recently in the Journal of Cetacean Research and Management, following detailed sea surveys dating back to 2015.

Dr Berrow, the principal investigator on the study, noted that the deep-diving tendency of sperm whales makes them difficult to observe at sea – they can spend nearly an hour in depths below 300m. 

Only 11 individuals were sighted during 388 hours of effort, he said, but 391 acoustic detections were recorded.

“Each whale was pinpointed by comparing the exact time that each click arrived at each hydrophone in the array and then triangulating bearings from sequential clicks over extended encounters,” he said.

The whales seemed to prefer seabed areas that sloped to the northwest, including the Erris and Rockall Basins. 

There was also a dense concentration of sperm whales in the South Brona Basin canyon system near 350km west of Co Kerry

The surveys were carried out from the Marine Institute’s RV Celtic Voyager and the yacht Song of the Whale, operated by Marine Conservation Research Ltd.

The study was part of the ObSERVE-Acoustic project funded by the Department of Communications, Climate Action and the Environment and the National Parks and Wildlife Service.

#MarineWildlife - Locals near Magheraroarty Beach in Co Donegal were left with a smelly situation last week after the remains of a whale buried on the strand were washed back onto the surface in a matter of days.

According to The Irish Times, the sperm whale carcass was first found beached on Friday 19 June and buried under the sand where it was found by Donegal County Council over that weekend.

However, on Monday 22 June the cetacean carcass reappeared after it was washed back out from its burial place with the tide.

And in its more advanced decomposing state, the noxious odour was beginning to cause a stink among regular beach users and locals alike. The Irish Times has more on the story HERE.

#whale – A marine biologist who attempted to cut open a dead Sperm Whale beached in the Faeroe islands last Tuesday (November 26) narrowly escaped being dosed in entrails when the poor dead creature exploded.

A video clip, shown on Faroese Television, showed a washed-up dead sperm whale explode, spraying entrails. The dead whale had been lying on the beach for two days after it got stuck in waters between the Faroe Islands' two biggest islands. On Tuesday, marine biologist Bjarni Mikkelsen was dispatched to cut it open. As he did so, the whale exploded - the explosion being the result of methane gas accumulating during the dying process.

Laast October in Baltimore, West Cork a whale carcass cretaed a 'Rancid Oil Slick' in a conservation area off the south west coast of Ireland after it died in the Baltimore harbour and was towed offshore.

#MarineWildlife - The carcass of a 30-metre sperm whale that washed ashore on the Dingle Peninsula last week is still lying on the beach, the Irish Examiner reported yesterday.

The body of the giant cetacean, which is believed to have died at sea, washed up at Fermoyle near Castlegregory, and has been inspected by staff from Kerry County Council.

It's hoped that the tide will rise high enough to carry the rotting carcass back to sea, but if necessary the council said it would take measures to remove it - particularly with the start of the Easter break this week.

Sperm whales - as seen recently by 'Cetaeans on the Frontier' surveyors on the edge of the continental shelf - are an unusual occurrence on Ireland's southwest coast, which normally plays host to humpback, minke and pilot whales, the latter of which commonly strand on the coasts of Cork and Kerry.

Elsewhere in the Kingdom, as reported earlier today on Afloat.ie, Fenit RNLI were joined by three local families to help give a fighting chance to a dolphin that stranded on a remote beach on Fenit Island last night.

#MARINE WILDLIFE - Three whales and a dolphin were found beached over the past few days along Ireland's west coast, according to the Belfast Telegraph.

Dr Simon Berrow of the Irish Whale and Dolphin Group confirmed that reports had been received of a bottlenose whale on White Strand in Co Clare, a pilot whale on Fintra Beach in Co Donegal and a dolphin in Silverstrand, Co Galway - all found dead.

The latest find was a male sperm whale stranded on Omey Island in Co Galway, shed of its skin and with a broken lower jaw.

"Chances are it died offshore and got washed in with the wind," said Berrow.

The IWDG said such strandings were relatively common, although as reported on Afloat.ie earlier this year there has been growing concern over the rising number of dolphin deaths along the south coast in particular.

New evidence is indicating that wild salmon are adapting to climate change by feeding in colder waters, The Irish Times reports.
According to salmon expert Dr Ken Whelan, wild salmon are now diving as far as 800m below the surface - normally the preserve of the sperm whale - to feed for periods of up to 24 hours during winter months.
They are also travelling closer to the polar ice fields, in response to the warming of the Atlantic Ocean.
The change in behaviour was noted at a salmon summit in France attended by more than 100 fishery managers and scientists from across Europe, which was convened to discuss the threat of climate change to wild salmon stocks at sea.
Plankton levels are particularly affected by the changing wind and ocean currents, said Dr Whelan of findings from the EU-funded Salsea programme, which he led.
“Surviving the first winter at sea seems to be the key challenge for these stocks, and the salmon in the northern states like Norway and Russia, seems to be less affected,” he said.
But the recent return of wild salmon to the Tolka in Dublin, as well as healthy returns along other inland waterways, highlighted that the news was not all doom and gloom.

A sperm whale that beached on a sand spit in Dungarvan, Co Waterford on Friday has died.
The male whale had been spotted off the coast in the 24 hours before it was discovered 'live stranded' on Cunnigar Strand.
Rescuers said there was "no effective way" of refloating the 10+ metre long whale from what became its final resting place.
"Once they come this far inshore they are pretty much doomed," the Irish Whale and Dolphin Group's (IWDG) Pádraig Whooley told the Irish Examiner.
No decision has yet been made regarding disposal of the whale carcass, but Irish Weather online quotes Whooley as saying it is "a wasted opportunity when these magnificent specimens are simply hauled off for incineration".

The Irish Coast Guard

The Irish Coast Guard is Ireland's fourth 'Blue Light' service (along with An Garda Síochána, the Ambulance Service and the Fire Service). It provides a nationwide maritime emergency organisation as well as a variety of services to shipping and other government agencies.

The purpose of the Irish Coast Guard is to promote safety and security standards, and by doing so, prevent as far as possible, the loss of life at sea, and on inland waters, mountains and caves, and to provide effective emergency response services and to safeguard the quality of the marine environment.

The Irish Coast Guard has responsibility for Ireland's system of marine communications, surveillance and emergency management in Ireland's Exclusive Economic Zone (EEZ) and certain inland waterways.

It is responsible for the response to, and co-ordination of, maritime accidents which require search and rescue and counter-pollution and ship casualty operations. It also has responsibility for vessel traffic monitoring.

Operations in respect of maritime security, illegal drug trafficking, illegal migration and fisheries enforcement are co-ordinated by other bodies within the Irish Government.

On average, each year, the Irish Coast Guard is expected to:

  • handle 3,000 marine emergencies
  • assist 4,500 people and save about 200 lives
  • task Coast Guard helicopters on missions

The Coast Guard has been around in some form in Ireland since 1908.

Coast Guard helicopters

The Irish Coast Guard has contracted five medium-lift Sikorsky Search and Rescue helicopters deployed at bases in Dublin, Waterford, Shannon and Sligo.

The helicopters are designated wheels up from initial notification in 15 minutes during daylight hours and 45 minutes at night. One aircraft is fitted and its crew trained for under slung cargo operations up to 3000kgs and is available on short notice based at Waterford.

These aircraft respond to emergencies at sea, inland waterways, offshore islands and mountains of Ireland (32 counties).

They can also be used for assistance in flooding, major inland emergencies, intra-hospital transfers, pollution, and aerial surveillance during daylight hours, lifting and passenger operations and other operations as authorised by the Coast Guard within appropriate regulations.

Irish Coastguard FAQs

The Irish Coast Guard provides nationwide maritime emergency response, while also promoting safety and security standards. It aims to prevent the loss of life at sea, on inland waters, on mountains and in caves; and to safeguard the quality of the marine environment.

The main role of the Irish Coast Guard is to rescue people from danger at sea or on land, to organise immediate medical transport and to assist boats and ships within the country's jurisdiction. It has three marine rescue centres in Dublin, Malin Head, Co Donegal, and Valentia Island, Co Kerry. The Dublin National Maritime Operations centre provides marine search and rescue responses and coordinates the response to marine casualty incidents with the Irish exclusive economic zone (EEZ).

Yes, effectively, it is the fourth "blue light" service. The Marine Rescue Sub-Centre (MRSC) Valentia is the contact point for the coastal area between Ballycotton, Co Cork and Clifden, Co Galway. At the same time, the MRSC Malin Head covers the area between Clifden and Lough Foyle. Marine Rescue Co-ordination Centre (MRCC) Dublin covers Carlingford Lough, Co Louth to Ballycotton, Co Cork. Each MRCC/MRSC also broadcasts maritime safety information on VHF and MF radio, including navigational and gale warnings, shipping forecasts, local inshore forecasts, strong wind warnings and small craft warnings.

The Irish Coast Guard handles about 3,000 marine emergencies annually, and assists 4,500 people - saving an estimated 200 lives, according to the Department of Transport. In 2016, Irish Coast Guard helicopters completed 1,000 missions in a single year for the first time.

Yes, Irish Coast Guard helicopters evacuate medical patients from offshore islands to hospital on average about 100 times a year. In September 2017, the Department of Health announced that search and rescue pilots who work 24-hour duties would not be expected to perform any inter-hospital patient transfers. The Air Corps flies the Emergency Aeromedical Service, established in 2012 and using an AW139 twin-engine helicopter. Known by its call sign "Air Corps 112", it airlifted its 3,000th patient in autumn 2020.

The Irish Coast Guard works closely with the British Maritime and Coastguard Agency, which is responsible for the Northern Irish coast.

The Irish Coast Guard is a State-funded service, with both paid management personnel and volunteers, and is under the auspices of the Department of Transport, Tourism and Sport. It is allocated approximately 74 million euro annually in funding, some 85 per cent of which pays for a helicopter contract that costs 60 million euro annually. The overall funding figure is "variable", an Oireachtas committee was told in 2019. Other significant expenditure items include volunteer training exercises, equipment, maintenance, renewal, and information technology.

The Irish Coast Guard has four search and rescue helicopter bases at Dublin, Waterford, Shannon and Sligo, run on a contract worth 50 million euro annually with an additional 10 million euro in costs by CHC Ireland. It provides five medium-lift Sikorsky S-92 helicopters and trained crew. The 44 Irish Coast Guard coastal units with 1,000 volunteers are classed as onshore search units, with 23 of the 44 units having rigid inflatable boats (RIBs) and 17 units having cliff rescue capability. The Irish Coast Guard has 60 buildings in total around the coast, and units have search vehicles fitted with blue lights, all-terrain vehicles or quads, first aid equipment, generators and area lighting, search equipment, marine radios, pyrotechnics and appropriate personal protective equipment (PPE). The Royal National Lifeboat Institution (RNLI) and Community Rescue Boats Ireland also provide lifeboats and crews to assist in search and rescue. The Irish Coast Guard works closely with the Garda Siochána, National Ambulance Service, Naval Service and Air Corps, Civil Defence, while fishing vessels, ships and other craft at sea offer assistance in search operations.

The helicopters are designated as airborne from initial notification in 15 minutes during daylight hours, and 45 minutes at night. The aircraft respond to emergencies at sea, on inland waterways, offshore islands and mountains and cover the 32 counties. They can also assist in flooding, major inland emergencies, intra-hospital transfers, pollution, and can transport offshore firefighters and ambulance teams. The Irish Coast Guard volunteers units are expected to achieve a 90 per cent response time of departing from the station house in ten minutes from notification during daylight and 20 minutes at night. They are also expected to achieve a 90 per cent response time to the scene of the incident in less than 60 minutes from notification by day and 75 minutes at night, subject to geographical limitations.

Units are managed by an officer-in-charge (three stripes on the uniform) and a deputy officer in charge (two stripes). Each team is trained in search skills, first aid, setting up helicopter landing sites and a range of maritime skills, while certain units are also trained in cliff rescue.

Volunteers receive an allowance for time spent on exercises and call-outs. What is the difference between the Irish Coast Guard and the RNLI? The RNLI is a registered charity which has been saving lives at sea since 1824, and runs a 24/7 volunteer lifeboat service around the British and Irish coasts. It is a declared asset of the British Maritime and Coast Guard Agency and the Irish Coast Guard. Community Rescue Boats Ireland is a community rescue network of volunteers under the auspices of Water Safety Ireland.

No, it does not charge for rescue and nor do the RNLI or Community Rescue Boats Ireland.

The marine rescue centres maintain 19 VHF voice and DSC radio sites around the Irish coastline and a digital paging system. There are two VHF repeater test sites, four MF radio sites and two NAVTEX transmitter sites. Does Ireland have a national search and rescue plan? The first national search and rescue plan was published in July, 2019. It establishes the national framework for the overall development, deployment and improvement of search and rescue services within the Irish Search and Rescue Region and to meet domestic and international commitments. The purpose of the national search and rescue plan is to promote a planned and nationally coordinated search and rescue response to persons in distress at sea, in the air or on land.

Yes, the Irish Coast Guard is responsible for responding to spills of oil and other hazardous substances with the Irish pollution responsibility zone, along with providing an effective response to marine casualties and monitoring or intervening in marine salvage operations. It provides and maintains a 24-hour marine pollution notification at the three marine rescue centres. It coordinates exercises and tests of national and local pollution response plans.

The first Irish Coast Guard volunteer to die on duty was Caitriona Lucas, a highly trained member of the Doolin Coast Guard unit, while assisting in a search for a missing man by the Kilkee unit in September 2016. Six months later, four Irish Coast Guard helicopter crew – Dara Fitzpatrick, Mark Duffy, Paul Ormsby and Ciarán Smith -died when their Sikorsky S-92 struck Blackrock island off the Mayo coast on March 14, 2017. The Dublin-based Rescue 116 crew were providing "top cover" or communications for a medical emergency off the west coast and had been approaching Blacksod to refuel. Up until the five fatalities, the Irish Coast Guard recorded that more than a million "man hours" had been spent on more than 30,000 rescue missions since 1991.

Several investigations were initiated into each incident. The Marine Casualty Investigation Board was critical of the Irish Coast Guard in its final report into the death of Caitriona Lucas, while a separate Health and Safety Authority investigation has been completed, but not published. The Air Accident Investigation Unit final report into the Rescue 116 helicopter crash has not yet been published.

The Irish Coast Guard in its present form dates back to 1991, when the Irish Marine Emergency Service was formed after a campaign initiated by Dr Joan McGinley to improve air/sea rescue services on the west Irish coast. Before Irish independence, the British Admiralty was responsible for a Coast Guard (formerly the Water Guard or Preventative Boat Service) dating back to 1809. The West Coast Search and Rescue Action Committee was initiated with a public meeting in Killybegs, Co Donegal, in 1988 and the group was so effective that a Government report was commissioned, which recommended setting up a new division of the Department of the Marine to run the Marine Rescue Co-Ordination Centre (MRCC), then based at Shannon, along with the existing coast radio service, and coast and cliff rescue. A medium-range helicopter base was established at Shannon within two years. Initially, the base was served by the Air Corps.

The first director of what was then IMES was Capt Liam Kirwan, who had spent 20 years at sea and latterly worked with the Marine Survey Office. Capt Kirwan transformed a poorly funded voluntary coast and cliff rescue service into a trained network of cliff and sea rescue units – largely voluntary, but with paid management. The MRCC was relocated from Shannon to an IMES headquarters at the then Department of the Marine (now Department of Transport) in Leeson Lane, Dublin. The coast radio stations at Valentia, Co Kerry, and Malin Head, Co Donegal, became marine rescue-sub-centres.

The current director is Chris Reynolds, who has been in place since August 2007 and was formerly with the Naval Service. He has been seconded to the head of mission with the EUCAP Somalia - which has a mandate to enhance Somalia's maritime civilian law enforcement capacity – since January 2019.
