The Irish Whale and Dolphin Group (IWDG) has appealed for the public to keep a look-out after a spate of marine wildlife strandings reported in recent days.

Half of the six reports were live strandings, the group says, but only one animal was successfully returned to the water.

In Galway, a common dolphin live stranded with serious injuries but died shortly after IWDG members arrived at the scene.

Another common dolphin live stranded at Mulranny in Co Mayo. Local woman Catherine Hanley, who reported the stranding, managed to refloat this dolphin with her group and it has not been seen since.

In Co Donegal, a “very emaciated” Cuvier’s beaked whale live stranded at Dooey Beach in Downings, on the Rosguill peninsula, but died shortly after.

Elsewhere, the remains of three more cetaceans were reported around the coast in recent days.

In Rathmullen, Co Donegal, the carcass of a common dolphin appears to match video of a dolphin swimming in the area the previous day, suggesting a live stranding.

At Greenore in Co Louth, at the mouth of Carlingford Lough, a common dolphin in “very fresh condition” was reported to the local IWDG group.

And in Passage East, Co Waterford, a carcass in “very poor” condition has been logged as “dolphin species” as its advanced state of composition made further identification impossible.

The IWDG appeals for the public to report all strandings “so we respond immediately and monitor the status of our whales and dolphins”.

#MarineWildlife - The UK’s Natural History Museum has made available for the first time a vast trove of whale and dolphin stranding records in British and Irish waters.

The data covers the years 1913 to 1989, filling in a significant gap before the Irish Whale and Dolphin Group’s stranding scheme began in 1991.

Over the years many entries were submitted by the coastguard, fishermen and members of the public — including a detailed record of a harbour porpoise found in Co Cork in 1913, the very first card in the data set.

PhD candidate Ellen Coombs is combing through the records to determine what picture “one of the longest systematic cetacean stranding data sets in the world” reveals for the status of cetacean species in our waters.

And already there have been some important finds, such as occasional records of deep-diving Cuvier’s beaked whales over the decades — not to mention a double stranding of narwhals in 1949.

The data also correlates with already known trends, such as the sharp decline in blue whale records with the expansion of commercial whaling in the early 20th century.

#MarineWildlife - Unusual weather for this time of year may be responsible for a recent spate of whale and dolphin strandings on the Cork coast in the past week.

The Irish Examiner reports that among the eight strandings were the carcass of a sperm whale on Long Strand in West Cork and a dolphin with fishing line around its beak in Schull.

However, the Irish Whale and Dolphin Group’s (IWDG) Mick O’Connell said that while the statistic was high within such a short timeframe, it was not necessarily a mystery.

“We normally get the same thing every year,” said the IWDG stranding officer. “It is usually more in the southwest and west, but this year, I suppose we have had more southeast winds, which probably explains it.”

O’Connell added that the strandings are “only a percentage of what is actually dead at sea” — and that post-mortems may “shed some light in their deaths”.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed its dismay at another record year for cetacean standings around the Irish coast.

The first eight months of 2017 alone have seen 201 recorded strandings - up 30% compared to the same period in the last two years.

“As in recent years, the numbers of dead common dolphins recorded are very high, with 78 records for this species to the end of August 2017 accounting for 39% of all strandings,” says IWDG strandings officer Mick O’Connell, who notes that the numbers of dead dolphins washing ashore in late winter and spring has grown unusually high.

“Even in a series of years with particularly high numbers of this species stranding since 2011, 2017 is well ahead of the previous two ‘record’ years by the end of August — 66 in 2016 and 53 in 2013.

“These are, of course, minimum numbers as we don't know how many dead animals go unrecorded and also many unidentified dolphins which aren't identifiable to species level are likely to be common dolphins,” he adds.

The IWDG is currently working with the Marine Institute, Department of Agriculture and National Parks and Wildlife service on a post-mortem scheme for common dolphins, striped dolphins and harbour porpoises which is hoped will shed new light on what might be causing this alarming rise in cetacean deaths.

Meanwhile, there was more positive news from the recent all-Ireland whale watch at the end of August, where three-quarters of the 20 sites around the island recorded sightings.

Around 1,300 whale watchers and wildlife enthusiasts spotted eight species of cetacean between them — with the busiest site at Loop Head in Co Kerry, where 120 lucky visitors got to see two humpback whales, five minke whales, six bottlenose and a whopping 50 common dolphins.

Other marine wildlife species spotted around the coast included Risso’s dolphins, blue fin tuna, ocean sunfish and grey seals.

More recently, the IWDG’s Celtic Mist embarked on a week-long survey of the waters around North and West Kerry, and its crew shared a video of some of their sightings.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has reiterated the need for localised stranding plans after the death of two common dolphins that stranded in Mayo's Blacksod Bay in late July.

Aoife Foley of the IWDG writes that the two dolphins were part of a pod of five that were spotted close to the shore at Mullaghroe Beach on Saturday 23 July.

A team from the Broadhaven Bay Marine Mammal Monitoring Programme joined local marine biologist Machiel Oudejans to move the dolphins, which did not appear to be injured or in obviously poor health, back into deeper waters and out to sea.

However, the following afternoon a member of the programme team saw that two of the marine mammals had stranded on the same stretch of beach, which Foley says is "notorious for common dolphin strandings in Blacksod Bay".

Despite best efforts, by Tuesday 26 July one of the animals had died and the other had to be put down by the National Parks and Wildlife Service.

#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.

#MarineWildlife - Strandings of common dolphins for the first two months of the year are at their second highest since records began in 2002, says the Irish Whale and Dolphin Group (IWDG).

A total of 28 confirmed standings were recorded in the IWDG's strandings database in January and February of this year, just below 2013's worst figures so far when 31 were reported.

That compares to an average of fewer than six reports for the same period each year between 2002 and 2010.

The current decade has seen a significant jump in recorded figures, with 18 reports of dolphin standings in 2011 compared to just two in the same months in 2010.

Many of the dolphins found this year were recorded in the North West, a great number of them drowned according to post-mortem results, while others showed signs of being tangled in fishing gear, which suggests they were bycatch in the nets of supertrawlers that ply the seas off Donegal, Sligo and Mayo.

"While there is no conclusive proof of what vessels are involved, the evidence points to the presence of large (c.100m) foreign registered freezer trawlers fishing in Irish offshore waters."

That's according to the IWDG's strandings officer Mick O'Connell, who warns that "the number of bycaught dolphins that actually get washed ashore and recorded as stranded may be only a small percentage of the actual number of dead animals."

The IWDG reiterates the call for independent observers to be placed on supertrawlers in Irish waters, following controversy over the visit of one of the world's largest fishing boats last November.

In other news, Scotland's Press and Journal reports that a humpback whale was killed after getting trapped in fishing ropes in the Outer Hebrides.

The juvenile whale was found dead on the Isle of Barra this week with the "classic signs of having suffered entanglement."

#dolphinstrandings – As Afloat.ie reported earlier, a  County Mayo woman Ina Kruger successfully rescued a stranded dolphin at Easter on Keem beach, Achill. Originally rescued on Easter Sunday, the dolphin returned to the beach where the body of a second dolphin was discovered. Fortunately, the second rescue attempt was more successful and the dolphin hasn't been seen since.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed its dismay at the continued rise in whale, dolphin and porpoise strandings around Ireland in 2013.

"The question was whether the numbers for 2012 were just a temporary ‘blip’ in the trend and would the figures for Ireland return to a more ‘normal’ 145 or so for 2013," writes IWDG strandings officer Mick O'Connell on the group's website.

"Well, as we head towards the start of winter, we can see that the answer is a most definite ‘no’."

O'Connell explains that by the end of the first week of October this year, the group had received validated reports for 175 cetacean stranding incidents - matching the total for the 12 months of 2012.

"With a good few weeks left until the years end, it’s likely that for the first time ever, the strandings database will receive 200-plus cetacean stranding records," he writes, adding that there is as yet "no explanation as to the cause or causes for the significant increase in figures" - though it's so far clear that the biggest increase is among common dolphins.

#MarineWildlife - The Guardian reports on new research which proves that military sonar has a direct effect on the behaviour of whales in our oceans - even leading to mass strandings.

The studies, part funded by the US Navy, found that beaked whales where particularly sensitive to sonar - and that even blue whales, the largest animals on earth, were distracted from feeding by the subsurface noise.

It's long been feared that the use of sonar is to blame for unusual behaviour among whales, who navigate and communicate with each other over long distances using sound.

As previously reported on Afloat.ie, the Irish Whale and Dolphin Group (IWDG) identified sonar activity by Royal Navy submarines as a possible cause of a the mass stranding of pilot whales in Donegal in November 2010, in which as many as 35 whales died.

Now for the first time, sonar has been proven to affect behaviour of cetaceans to a detrimental degree, confirming for many a connection between the use of sonar technology and recordings of whale and dolphin strandings identified since the 1950s. The Guardian has much more on the story HERE.

In more positive whale-related news, the IWDG reports that its next Cape Clear summer whalewatching course over the weekend of 26-28 July is "filling up nicely".

Places are still available but as it coincides with the tourism high season in West Cork, anyone interested is advised to book sooner than later to ensure they have someone to stay nearby.

The most recent weekend course over the June bank holiday witnessed numerous harbour porpoises and common dolphins, but its hoped the elusive whales will make an appearance next time round!

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.”
