Falling demand for whale meat has prompted Iceland to announce and end to commercial whaling from 2024, as RTÉ News reports.

The move will leave Norway and Japan as the only countries that hunt whales for commercial purposes.

In an article published in the Morgunbladid newspaper, Icelandic fisheries minister Svandis Svavarsdottir said: “There is little proof that there is any economic advantage to this activity.”

Despite having sizeable annual quotas for minke and fin whales, neither of Iceland’s two main licence holders have hunted whales for a full season since 2018 — and only one has been killed in the past three years.

Meanwhile, among other issues affecting exports, Japan’s resumption of whaling has all but eliminated demand for such meat from the Icelandic fishery.

Iceland’s relationship with the whales in its waters was documented in a 2020 film that followed an Irish Whale and Dolphin Group expedition in search of humpback whales, as previously reported on Afloat.ie.

A sea angler got more than he bargained for last week when he was thrown from his boat by a whale while fishing off West Cork.

As CorkBeo reports, Cris Lane was angling with friend Dave McCann off Courmacsherry last Monday (3 August) when they noticed a bounty of marine wildlife — both dolphins and small whales — close by, and their vessel was bumped by a passing minke whale.

The hit was enough to send Lane flying overboard — but thanks to his lifejacket keeping him buoyant, he was able to quickly get out of the cold water and back on board.

The public has been urged to “stay clear” of a minke whale carcass found washed up on Tyrella beach in Co Down yesterday morning (Monday 9 September).

According to ITV News, the 27ft marine wildlife giant was found with what appeared to be a piece of fishing gear wrapped around its tail — suggesting that it may have been caught up in a net off the coast.

Newcastle Coastguard attended the “distressing scene” on request by NI Fisheries Protection, said BBC News, which also noted that a similar whale carcass stranded in a Donegal estuary on Lough Swilly a month ago.

#MarineWildlife - Galley Head was the place to see Ireland’s biggest recorded gathering of minke whales in recent weeks, as TheJournal.ie reports.

Cork Whale Watch skipper Colin Barnes estimated more than 50 minke whales feeding off the coast of West Cork on Sunday 29 April.

“It is remarkable how the month of April extending into May, which was once considered by us whale watchers to be low season for any species, is rapidly becoming one of the busiest times of the year,” said Pádraig Wholley, sightings officer with the Irish Whale and Dolphin Group (IWDG).

West Cork is also one of the best places in Ireland to see humpback whales, who can count marine wildlife specialist Emer Keaveney among their biggest fans.

The “ambassadors of the world’s oceans” are coming to Irish waters in increasing numbers, as Tom MacSweeney stated earlier today.

And they are also the subject of a groundbreaking expedition to Iceland this summer on board the IWDG’s research vessel Celtic Mist.

Elsewhere, the sighting of a dolphin attacking a porpoise off Scotland could point to increased competition over a food source.

As the Irish Examiner reports, dramatic images captured in the Moray Firth earlier this month were part of a series of ‘unusual’ sightings of bottlenose dolphin attacks.

#MarineWildlife - A retired coastguard volunteer has spoken of the “amazing” experience of helping a stranded whale to safety in Northern Ireland on Tuesday (3 October).

As BBC News reports, commercial diver John Lowry diverted from his commute home to the scene, on a sandbank near Newcastle promenade in Co Down, and immediately set to work.

“The first thing I did was to try and get the head of the whale pointed out to sea, so that if I could get him to move that he was going directly out to sea,” he said, explaining how minke whales are easily disoriented when stranded.

Lowry spent up to 15 minutes slowly and painstakingly urging the whale forward with each small wave — until finally it kicked into deeper water, much to the delight of locals and children who were watching the ordeal.

However, Lowry offered a word of caution for anyone else thinking of attempting a similar rescue.

“Don't approach [a whale] unless you have experience of this kind of thing, because they are very powerful,” said the Newcastle man, who previously helped save a beached whale when he served with South Down Coastguard.

In other news, a whale died in the waters between Ireland and Scotland coast after getting entangled in a rope — the first such recorded occurrence in 25 years.

According to Deadline News, the Northern Bottlenose whale — a species rarely sighted in the waters of the continental shelf — was found with wounds caused by rope, and is though to have drowned before it washed up at Ardentinny in Western Scotland in late September.

“Entanglement is known to be a global problem particularly for large whales,” says the Scottish Marine Stranding Scheme.

#MarineWildlife - An “extremely rare” pod of minke whales has been sighted in the Irish Sea off the Isle of Man this week.

According to BBC News, the pod comprising as many as 20 minke whales was engaged in a “feeding frenzy” as seen by members of Manx Whale and Dolphin Watch on Wednesday (13 September)

The marine wildlife species is a regular visitor to the waters around the Isle of Man, but sightings are usually of solitary adults or small pods.

It’s believed that spawning herring have attracted them in much greater numbers. BBC News has more on the story HERE.

In other marine wildlife news, the Irish Whale and Dolphin Group’s AGM takes place on Sunday 8 October at the Middle Country Café in Cloughjordan, Co Tipperary. Details are available from the IWDG website.

#MarineWildlife - The Irish Whale and Dolphin Group’s Pádraig Whooley says he has “lost count” of the number of minke whales seen off West Cork in recent days, as The Irish Times reports.

Whales of various cetacean species are now arriving in Ireland in larger numbers much earlier in the year than their usual appearance in autumn, according to the IWDG’s sightings co-ordinator.

Minke whale numbers between Union Hall and Galley Head have been “exceptional” since last week, says Whooley — who also notes that a pod of humpbacks familiar to West Kerry coastal residents has been feeding off Cork over the past fortnight, while the whale known as Boomerang has been spotted off Waterford.

Elsewhere, the Air Corps Maritime Squadron recently captured some astonishing images of sharks feeding on a whale carcass some 200km northwest of Donegal.

“It's not often that we get sent such clear images of a dead cetacean being scavenged on by several sharks,” said IWDG standings officer Mick O'Connell, “but it does give an indication of the importance of dead animals in the food chain.”

#MarineWildlife - A number of dead minke whales found off the Dingle Peninsula in recent months have puzzled locals and experts alike, as TheJournal.ie reports.

The carcasses of three juvenile minkes have been spotted in the region since April, comprising 25% of all Irish minke whale standings since records began in 2000.

A fourth whale carcass was found on the shore at Killough in Co Down last week, according to BBC News.

But no one seems to know the reasons for these marine wildlife deaths, with the lack of a post-mortem scheme for whale strandings making matters even cloudier.

Mick O’Connell, strandings co-ordinator of the Irish Whale and Dolphin Group (IWDG), believes the phenomenon is localised to the Dingle Bay area.

Yet while the species is a regular visitor to the Blasket Islands and environs, O'Connell says it's "very unusual to have so many dead ones in the one small area, in the space of 10 or 12 weeks."

The same region also saw a number of unsubstantiated dolphin deaths in recent weeks, which one fishery expert suggested might be connected with the presence of so-called 'supertrawlers' fishing in the area.

Similar concerns were raised earlier in the year when a spike in common dolphin standings, primarily in the North West – totalling 28 for January and February alone – coincided with reports of supertrawler activity off the Dongeal, Sligo and Mayo coasts.

Sightings of juvenile minke whales off Scotland’s west coast increased in 2015 to the highest ever recorded within a survey season, during marine research expeditions carried out by Hebridean Whale and Dolphin Trust – indicating either a significant increase in actual numbers or an influx of minke whales from elsewhere.

The charity’s 2015 research season also recorded the highest annual number of common dolphin sightings since its expeditions began, with 723 individuals observed over 63 encounters. The common dolphin was once uncommon in the Hebrides, but the trust’s encounter rate with the species has more than doubled over the past 12 years, also for reasons that remain unclear.

Kerry Froud, Hebridean Whale and Dolphin Trust Biodiversity Officer, said: “These intriguing changes in Scotland’s marine life highlight the importance of long-term monitoring of cetaceans – so that we can better understand what is happening in our waters, and then make management recommendations to better protect this world-class area of marine biodiversity.”

The studies were carried out between May to October by scientists and volunteers on board Silurian, the trust’s dedicated research yacht. The research forms part of the trust’s unique long-term monitoring of whales, dolphins and porpoises – collectively known as cetaceans – in the Hebrides. Information on basking sharks is also collected during the surveys.

A steady increase in the encounter rate with minke whale juveniles since 2011 was particularly marked this year, with the highest rate of young whales recorded since the trust started boat-based surveys in 2003. The 2015 surveys documented an encounter rate of 1 young minke whale per 286 km – three times the average over the trust’s entire dataset.

The minke whale is the smallest of the baleen whales – species which utilise baleen plates rather than teeth to feed – in the North Atlantic, measuring up to 10 metres in length, and is the most commonly sighted baleen whale species in the UK. Hebridean Whale and Dolphin Trust holds an identification catalogue of 125 minke whales known to have visited the Hebrides – of which some individuals return to the same areas annually, while others may only be passing through.

While an increase in the encounter rate with young minke whales is encouraging, there are still very serious issues regarding the conservation of this migratory species. To the north of Scotland, both Iceland and Norway still hunt minke whales. It remains unknown whether or not the minke whales that swim through Scottish waters frequent the waters where they risk being hunted.

The record number of common dolphin sightings – coupled with the most northerly sighting of the species ever recorded in September this year, off Tromso in Norway – suggests that changes are underway within our seas and oceans. The causes, and wider effects on the marine environment and other species, are still unclear – underlining the importance of on-going research.

Additionally, the number of white-beaked dolphin encounters almost doubled in comparison to 2014, although many of these encounters were made during one particular day of survey around the Butt of Lewis. This rarer, colder water species is confined to the north Atlantic and prefers temperate to sub-Arctic waters – meaning that the warming of Hebridean seas, at a rate of 0.5°C per decade, is expected to exert increased pressure on the populations found off Scotland’s west coast.

White-beaked dolphins have been the focus of acoustic research by Hebridean Whale and Dolphin Trust, with a study in 2013 discovering that white beaked dolphin populations off the east and west coasts of Scotland have distinct acoustic signatures, almost like accents.

Alongside warming seas and climate change, human activities causing increasing stress on cetaceans and basking sharks include fisheries by-catch, pollution, underwater noise and habitat loss.

Cetacean entanglement in litter and fishing gear can cause mobility problems, injury and even death, and the trust is working cooperatively with the fishing industry and other researchers in the UK to better understand this problem so that it can be addressed. This year, ironically whilst the Silurian crew was celebrating a volunteer’s 60th birthday, a bunch of balloons was retrieved from the water – a reminder that celebratory balloons, even if marketed as ‘biodegradable’, can have lasting consequences for our wider environment.

Silurian – previously used in filming of the BBC’s The Blue Planet series – covered more than 4,000 nautical miles in 2015, its crew of volunteers and marine scientists documenting more than 1,200 encounters with cetaceans and basking sharks, and recording almost 625 hours of underwater detections of cetaceans using specialist listening equipment.

Despite less than favourable weather conditions, the overall encounter rate remained steady, with eight sightings of cetaceans per 100 km recorded, compared to nine per 100 km in 2014 and five per 100 km in 2013.

The annual surveys depend on paying volunteers. In 2015, 69 dedicated volunteers clocked up 760 survey hours – working with marine scientists to conduct visual surveys and acoustic monitoring with hydrophones (underwater microphones) monitored by computers, and identifying individual cetaceans through photography of dorsal fins.

The trust – based in Tobermory on the Isle of Mull – is recruiting volunteers for its 2016 surveys, to live and work as citizen scientists onboard Silurian for expeditions of one to two weeks from April to September. Participation costs cover boat expenses, support the trust’s research programme and include accommodation, training, food and insurance. For details, contact Morven Russell at [email protected], call 01688 302620, or visit www.hwdt.org.

Hebridean Whale and Dolphin Trust has been monitoring marine mega fauna in the Hebrides for 13 years, and is the only organisation collecting long-term data on such a large scale on Scotland’s west coast. A short film about its marine surveys is above.

Western Scotland’s seas are one of Europe’s most important habitats for cetaceans and one of the UK’s most biologically productive areas. So far 24 of the world’s 83 cetacean species have been recorded in the region, many being national and international conservation priority species.

#MarineWildlife - The video above shows the shocking moment when a small boat of wildlife watchers was suddenly surrounded by six giant humpback whales.

As the Irish Mirror reports, the duo who captured this amazing footage were sailing in a Norwegian fjord when they saw the whales feeding on herring in the distance and decided to move closer for a better look.

But little did they imagine how close they would get!

Thankfully for the pair, their boat was barely rocked on the waves as the marine giants deftly manoeuvred around them.

"I felt very confident afterwards," said Svein Aasjord, one of the two sailors. "Whales have much more control than I had thought."

Although Irish whale watchers might not be treated to such sights in close quarters, the Northwest is currently a treat for anyone who wants to see minke whales in action.

The Irish Whale and Dolphin Group reports on what's become a trend for the species wintering off the Donegal coast between Bun on Inver and Bloody Foreland.

As many as six min whales were spotted in inshore waters within 200 metres the latter location three days ago, due most likely to the bounty of herring in the area.

For all you need on the Marine Environment - covering the latest news and updates on marine science and wildlife, weather and climate, power from the sea and Ireland's coastal regions and communities - the place to be is Afloat.ie.

Coastal Notes

The Coastal Notes category covers a broad range of stories, events and developments that have an impact on Ireland's coastal regions and communities, whose lives and livelihoods are directly linked with the sea and Ireland's coastal waters.

Topics covered in Coastal Notes can be as varied as the rare finding of sea-life creatures, an historic shipwreck with secrets to tell, or even a trawler's net caught hauling much more than just fish.

Other angles focusing the attention of Coastal Notes are Ireland's maritime museums, which are of national importance to maintaining access and knowledge of our nautical heritage, and those who harvest the sea using small boats based in harbours where infrastructure and safety pose an issue, plying their trade along the rugged wild western seaboard.

Coastal Notes tells the stories that are arguably as varied as the environment they come from, and which shape people's interaction with the natural world and our relationship with the sea.

Marine Wildlife

One of the greatest memories of any day spent boating around the Irish coast is an encounter with Marine Wildlife. It's a thrill for young and old to witness seabirds, seals, dolphins and whales right there in their own habitat. And as boaters fortunate enough to have experienced it will testify, even spotting a distant dorsal fin can be the highlight of any day afloat. Was that a porpoise? Was it a whale? No matter how brief the glimpse, it's a privilege to share the seas with Irish marine wildlife.

Thanks to our location in the North Atlantic, there appears to be no shortage of marine life to observe. From whales to dolphins, seals, sharks and other ocean animals, the Marine Wildlife category documents the most interesting accounts around our shores. And we're keen to receive your observations, your photos, links and video clips, too!

Also valuable is the unique perspective of all those who go afloat, from coastal sailing to sea angling to inshore kayaking to offshore yacht racing, as what they encounter can be of great importance to organisations such as the Irish Whale and Dolphin Group (IWDG). Thanks to their work we now know we share the seas with dozens of species who also call Ireland home. But as impressive as the list is, the experts believe there are still gaps in our knowledge. Next time you are out on the ocean waves, keep a sharp look out!

Weather

As an island in the North Atlantic, Ireland's fate is decided by Weather more so than many other European countries. When storm-force winds race across the Irish Sea, ferry and shipping services are cut off, disrupting our economy. When swollen waves crash on our shores, communities are flooded and fishermen brace for impact - both to their vessels and to their livelihoods.

Keeping abreast of the weather, therefore, is as important to leisure cruisers and fishing crews alike - for whom a small craft warning can mean the difference between life and death - as it is to the communities lining the coast, where timely weather alerts can help protect homes and lives.

Weather affects us all, and Afloat.ie will keep you informed on the hows and the whys.

Marine Science

Perhaps it's the work of the Irish research vessels RV Celtic Explorer and RV Celtic Voyager out in the Atlantic Ocean that best highlights the essential nature of Marine Science for the future growth of Ireland's emerging 'blue economy'.

From marine research to development and sustainable management, Ireland is developing a strong and well-deserved reputation as an emerging centre of excellence. Whether it's Wavebob ocean energy technology to aquaculture to weather buoys and oil exploration, the Marine Science category documents the work of Irish marine scientists and researchers and how they have secured prominent roles in many European and international marine science bodies.

Power From The Sea

The message from the experts is clear: offshore wind and wave energy is the future. And as Ireland looks towards the potential of the renewable energy sector, generating Power From The Sea will become a greater priority in the State's 'blue growth' strategy.

Developments and activities in existing and planned projects in the pipeline from the wind and wave renewables sector, and those of the energy exploration industry, point to the future of energy requirements for the whole world, not just in Ireland. And that's not to mention the supplementary industries that sea power projects can support in coastal communities.

Irish ports are already in a good position to capitalise on investments in offshore renewable energy services. And Power From The Sea can even be good for marine wildlife if done properly.

Aside from the green sector, our coastal waters also hold a wealth of oil and gas resources that numerous prospectors are hoping to exploit, even if people in coastal and island areas are as yet unsure of the potential benefits or pitfalls for their communities.

Changing Ocean Climate

Our ocean and climate are inextricably linked - the ocean plays a crucial role in the global climate system in a number of ways. These include absorbing excess heat from the atmosphere and absorbing 30 per cent of the carbon dioxide added to the atmosphere by human activity. But our marine ecosystems are coming under increasing pressure due to climate change.

The Marine Institute, with its national and international partners, works to observe and understand how our ocean is changing and analyses, models and projects the impacts of our changing oceans. Advice and forecasting projections of our changing oceans and climate are essential to create effective policies and management decisions to safeguard our ocean.

Dr Paul Connolly, CEO of the Marine Institute, said, “Our ocean is fundamental to life on earth and affects so many facets of our everyday activities. One of the greatest challenges we face as a society is that of our changing climate. The strong international collaborations that the Marine Institute has built up over decades facilitates a shared focusing on our changing ocean climate and developing new and enhanced ways of monitoring it and tracking changes over time.

“Our knowledge and services help us to observe these patterns of change and identify the steps to safeguard our marine ecosystems for future generations.”

The Marine Institute’s annual ocean climate research survey, which has been running since 2004, facilitates long term monitoring of the deep water environment to the west of Ireland. This repeat survey, which takes place on board RV Celtic Explorer, enables scientists to establish baseline oceanic conditions in Irish waters that can be used as a benchmark for future changes.

Scientists collect data on temperature, salinity, water currents, oxygen and carbon dioxide in the Atlantic Ocean. This high quality oceanographic data contributes to the Atlantic Ocean Observing System. Physical oceanographic data from the survey is submitted to the International Council for the Exploration of the Seas (ICES) and, in addition, the survey contributes to national research such as the VOCAB ocean acidification and biogeochemistry project, the ‘Clean Atlantic’ project on marine litter and the A4 marine climate change project.

Dr Caroline Cusack, who co-ordinates scientific activities on board the RV Celtic Explorer for the annual survey, said, “The generation of long-term series to monitor ocean climate is vital to allow us understand the likely impact of future changes in ocean climate on ecosystems and other marine resources.”

Other activities during the survey in 2019 included the deployment of oceanographic gliders, two Argo floats (Ireland’s contribution to EuroArgo) and four surface drifters (Interreg Atlantic Area Clean Atlantic project). The new Argo floats have the capacity to measure dissolved ocean and biogeochemical parameters from the ocean surface down to a depth of 2,000 metres continuously for up to four years, providing important information as to the health of our oceans.

During the 2019 survey, the RV Celtic Explorer retrieved a string of oceanographic sensors from the deep ocean at an adjacent subsurface moored station and deployed a replacement M6 weather buoy, as part of the Irish Marine Data Buoy Observation Network (IMDBON).

Funded by the Department of Agriculture, Food and the Marine, the IMDBON is managed by the Marine Institute in collaboration with Met Éireann and is designed to improve weather forecasts and safety at sea around Ireland. The data buoys have instruments which collect weather and ocean data including wind speed and direction, pressure, air and sea surface temperature and wave statistics. This data provides vital information for weather forecasts, shipping bulletins, gale and swell warnings as well as data for general public information and research.

“It is only in the last 20 years, meteorologists and climatologists have really began to understood the pivotal role the ocean plays in determining our climate and weather,” said Evelyn Cusack, Head of Forecasting at Met Éireann. “The real-time information provided by the Irish data buoy network is particularly important for our mariners and rescue services. The M6 data buoy in the Atlantic provides vital information on swell waves generated by Atlantic storms. Even though the weather and winds may be calm around our shores, there could be some very high swells coming in from Atlantic storms.”
