The Irish Whale and Dolphin Group (IWDG) is bringing stories from the Celtic Mist’s historic marine wildlife survey voyage around Iceland to libraries and other venues nationwide.

Already the IWDG has visited 10 venues across eight counties in its ‘On the Trail of the Whale’ tour, which continues tonight (Tuesday 19 February) at 7pm in Killarney Library.

In May last year a crew of marine scientists and enthusiasts set sail on the IWDG’s research yacht for a weeks-long return passage to the edge of the Arctic Circle in search of humpback whales, building “strong links with Iceland and its people” along the way.

Last month, IWDG members began sharing their experiences from the rewarding mission in images, stories and video of the voyage to audiences in libraries and other venues across the island of Ireland — beginning on 14 January at DLR LexIcon and since visiting Galway, Tralee, Monaghan town and Arklow, as well as Bangor and Warrenpoint in Northern Ireland and Dublin’s Poolbeg Yacht Club.

“Through the tour, we want to encourage people to get involved,” IWDG’s chief science officer Dr Simon Berrow told the Irish Examiner. “If even one person at every event we do gets interested [in marine life] and gets motivated, that’s fantastic.”

#MarineWildlife - Galway residents have a great opportunity to see a wild dolphin close to the city centre with the return of regular visitor to the Nimmo’s Pier area this week.

Nicknamed Nimmo, the solitary bottlenose dolphin was first sighted in the city in April 2015 and since then has become an annual fixture, appearing and staying longer each time.

The Irish Whale and Dolphin Group (IWDG) suggests this is a sign that the area around Galway city is now a “more important core feeding habitat for Nimmo”.

In other news, the IWDG’s research vessel Celtic Mist will embark on a series of week-long surveys this summer in search of humpback whales.

IWDG members are invited to join any of the nine legs, the first of which sets sail from 9-15 June (weather permitting) between Cork and Dingle/Fenit.

For details on how to book a place on any of these voyages and for further information, contact [email protected].

#MarineWildlife - Naval Service personnel on patrol with the LÉ Samuel Beckett encountered the carcass of a large whale some 50 nautical miles south-east of Ballycotton Lighthouse in the days after Christmas.

The “mystery whale” is neither a sighting (which only counts or living cetaceans) nor a stranding. But as the Irish Whale and Dolphin Group (IWDG) says, the encounter “serves to remind us that the animals that wash up on our shoreline may represent only a small percentage of the total number of cetaceans that expire at sea of presumably natural causes.”

IWDG sightings officer Pádraig Whooley said the location of these whale remains was “interesting as this area of the Celtic Sea has produced the most consistent large-whale sightings in recent months, with fairly regular sightings of fin whales from land-based sites between Ram Head, Ardmore extending east towards the Hook Head lighthouse.”

A dreary, stormy day in Dublin city centre was brightened with the appearance of a common dolphin swimming up the River Liffey as far as the Loopline Bridge.

The Irish Whale and Dolphin Group (IWDG) says it got its first reports early this morning (Wednesday 28 November) from the Jeanie Johnston, whose John O’Neill shot this video of the solo cetacean swimming loops in the river.

It was spotted swimming strongly as far west as Liberty Hall around lunchtime before heading back east and towards Dublin Bay.

Dolphins are known to develop kidney and skin problems on prolonged exposure to freshwater environments such as rivers.

However, the IWDG moved to assuage public concerns over this particular animal — saying that if it was swimming as strongly as sightings suggested, it would be more than able to swim back to sea.

It’s suggested that this short-beaked visitor may be one of a pod of some 20 dolphins known to be feeding off the East Coast this month.

#MarineWildlife - Video posted on social media over the weekend of two killer whales spotted off the Co Dublin coast has gone viral.

Trawlerman James Mac Cluskey used his phone to record a few seconds’ glimpse of the pair of male orcas, which came close to his boat some 8km off Rockabill on Saturday afternoon (17 November).

According to the Irish Whale and Dolphin Group (IWDG), it’s the second sighting of the largest species in the dolphin family off the East Coast in recent weeks, with another fisherman reporting an encounter some 22km off Skerries on 30 October.

And it’s believed the duo may be part of the Scottish West Coast Community Group, a unique orca pod long under threat of extinction owning to not having produced any calves for years.

Earlier this year, whales from this group were identified feeding off the Blasket Islands in Co Kerry, showing just how far their range extends.

#MarineWildlife - The Irish Whale and Dolphin Group’s (IWDG) datasets for cetacean sightings and strandings around the Irish coast are now back online after previous versions were corrupted in a cyber attack.

The launch coincided with the hosting in Kilkenny last week of the 25th meeting of the Global Biodiversity Information Facility (GBIF), an international network aimed at providing open access to data about life on Earth, marine wildlife included.

Twelve months of sighting and stranding data — including the recent ‘unusual mortality event’ of Cuvier’s beaked whales — can now be accessed, searchable by species, recorder, date and location, and all sightings are mappable.

Longer-term data is also available on request, for example for undergrad or postgraduate student projects.

All information in these datasets is provided by the IWDG’s loose network of volunteers around the island of Ireland, and is hailed by the group’s chief Dr Simon Berrow as “an excellent example of what can be achieved through citizen science.”

Dr Berrow adds: “Our recording schemes receive very little funding support. The sighting scheme gets no funding and currently the stranding scheme receives grant support of €10,000 from the NPWS, but it is not guaranteed and depends on other NPWS funding obligations.

“IWDG are committed to maintaining these recording schemes in the long term, as its only with time that we can identify trends; whether they are new threats to whale and dolphin populations or changing distributions driven by climate change and other large scale events.”

Both recording schemes have been run and supported by Pádraig Whooley and Mick O'Connell on behalf of the IWDG for over 20 years, and Dr Berrow says the information collected comprises “some of the most robust data in Europe to address key environmental issues and meet legal obligations.

“None of this would be possible without the IWDG members and non-members who go to great lengths to report strandings and sightings and take our calls to head out to the beaches and headlands all around Ireland to collect another data point. To them we offer our respect and thanks.”

Among the more recent sightings you’re likely to find is Boomerang, the humpback whale with the distinctive dorsal fin who’s made Ireland a regular stop since 2001.

He was spotted off the Clare and Kerry coast last month, as the Irish Mirror reports — and his return is a good omen for the quality of the ocean around Ireland, Dr Berrow suggests.

#MarineWildlife - The Department of Foreign Affairs will assist with an investigation into the extraordinary numbers of Cuvier’s beaked whale deaths in Irish waters over recent weeks.

Tánaiste and Foreign Affairs Minister Simon Coveney has “instructed his department, in consultation with the National Parks and Wildlife Service, to initiate discussions regarding these about large number of stranded Cuvier's beaked whales with the UK authorities,” according to the Irish Whale and Dolphin Group.

As previously reported on Afloat.ie, the IWDG had expressed concern over the large numbers of dead beaked whales washed up on Ireland’s North West coast last month.

The total of whale strandings since the beginning of August has now risen to 58 across Ireland and Scotland, many of them Cuvier’s or True’s beaked whales, as BBC News reports.

#MarineWildlife - The Papal visit brought numbers down for 2018’s Whale Watch Ireland last Saturday (25 August).

But some 950 wildlife enthusiasts still came out to 19 sites around the island of Ireland for the chance to spot some of the many whales, dolphins, porpoise and other wildlife in our waters.

Most sites reported a reduction in numbers, with only three seeing a modest increase. But it’s expected that next year’s turnout will be back to it regular size, coinciding as ever with events for Heritage Week.

Sightings were also lower this year — on average a 43% reduction on 2017’s records — with only three cetacean species spotted, namely harbour porpoise (50), common dolphins (40) and minke whales (5).

The success or otherwise of event is generally determined by the prevailing weather on the day, and thankfully most sites were treated to calm seas and clear skies which resulted in cetacean sightings at three-quarters of the sites covered at this year’s event.

Other species noted include grey seals, a basking shark and a sunfish.

Despite the lower attendance and sighting rates, the Irish Whale and Dolphin Group says it is “very pleased” with this year’s results.

“And we hope that among those who attended, there will be some new members for IWDG and dedicated whale watchers who are willing to volunteer some of their time and energy in furthering our understanding of the whales and dolphins that live in Irish coastal waters.”

The IWDG reports that usual there was a mix of both Irish and overseas visitors to the watches, and for many attending this was their first encounter with a cetacean in the wild in Irish waters.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has expressed concern in the wake of at least 16 Cuvier’s beaked whales washing up on the Irish coast this month.

Following the discovery of five beaked whales in a single day at the start of August, the IWDG says a minimum of 16 — a new Irish record — were recorded along the North West coast from Galway to Donegal between 3 and 22 August.

“During the same period, at least 13 were found in Scotland and two in Iceland,” said IWDG strandings officer Mick O’Connell.

“Previous studies have suggested that only a small number of dead animals actually get washed ashore and recorded, so the number of dead animals may be significantly higher.”

While no cause of death has been established, due to the poor condition of the carcasses, it appears that the animals all died around the same time, which “makes causes such as disease, plastic ingestion etc seem unlikely as these would tend to be spread out over a longer time period and perhaps geographical range,” O’Connell said.

“The behaviour and distribution of this species makes large-scale fisheries interaction also seem unlikely.”

Sonar use has been suspected as a cause in previous similar strandings. “Mass strandings of beaked whales coincidental with naval exercises have been recorded in Greece, the Canaries and the Bahamas,” O’Connell said.

According to TheJournal.ie, the Royal Navy denies its use of sonar in training exercises causes any harm to marine wildlife.

The Naval Service in Ireland does not use sonar on its vessels.

In more positive marine mammal news, Nuala Moore writes for Independent.ie about her experiences swimming in Dingle harbour with its longtime resident dolphin Fungie.

The open sea swimming enthusiast made headlines earlier this year for becoming the first Irish woman to swim off Cape Horn.

But in Dingle, she’s just another acquaintance for Fungie in his daily adventures.

#MarineWildlife - Ireland’s annual whale watch day takes place next Saturday 25 August — and the Irish Whale and Dolphin Group invites the public to join its land-based whale watches around the island of Ireland.

From 2pm to 5pm next Saturday, the IWDG’s volunteers will be raising awareness of the 25 species of cetaceans — porpoises, dolphins and whales — recorded to date in all Irish waters, and giving the public a great opportunity to look for and observe some of these wonderful marine mammals in their natural environment.

Whale Watch Ireland also provides IWDG researchers with a unique snapshot of whale and dolphin activity around the Irish coast on the day.

This annual, all-island citizen science event, organised by the IWDG in association with Inis the Energy of the Sea, is free and open to all as part of Heritage Week, co-ordinated by The Heritage Council.

All watches are land-based and will be led by experienced IWDG researchers and whale watchers, who will show you how to observe and identify some of the more commonly recorded cetacean species in Irish waters and who will be available to discuss the conservation work of the IWDG.

To make the most of the day, bring binoculars or a spotting scope, and dress appropriately for outdoor weather conditions. There are no boat trips involved and there is no guarantee that you will see whales or dolphins at your chosen site.

But at last year’s event, whales or dolphins were recorded at three-quarters of sites around the Irish coast.

The full list of watching locations, with watch leader contacts, is as follows:

Sharks in Irish waters

Irish waters are home to 71 species of shark, skates and rays, 58 of which have been studied in detail and listed on the Ireland Red List of Cartilaginous fish. Irish sharks range from small Sleeper sharks, Dogfish and Catsharks, to larger species like Frilled, Mackerel and Cow sharks, all the way to the second largest shark in the world, the Basking shark. 

Irish waters provide a refuge for an array of shark species. Tralee Bay, Co. Kerry provides a habitat for several rare and endangered sharks and their relatives, including the migratory tope shark, angel shark and undulate ray. This area is also the last European refuge for the extremely rare white skate. Through a European Maritime and Fisheries Fund (EMFF) project, Marine Institute scientists have been working with fishermen to assess the distribution, diversity, and monthly relative abundance of skates and rays in Tralee, Brandon and Dingle Bays.

“These areas off the southwest coast of Ireland are important internationally as they hold some of the last remaining refuges for angel shark and white skate,” said Dr Maurice Clarke of the Marine Institute. “This EMFF project has provided data confirming the critically endangered status of some species and provides up-to-date information for the development of fishery measures to eliminate by-catch.” 

Irish waters are also home to the Black Mouthed Catshark, Galeus melastomus, one of Ireland’s smallest shark species which can be found in the deep sea along the continental shelf. In 2018, Irish scientists discovered a very rare shark-nursery 200 nautical miles off the west coast by the Marine Institute’s ROV Holland 1 on a shelf sloping to 750 metres deep. 

There are two ways that sharks are born, either as live young or from egg casings. In the ‘case’ of Black Mouthed Catsharks, the nursery discovered in 2018, was notable by the abundance of egg casings or ‘mermaid’s purses’. Many sharks, rays and skate lay eggs, the cases of which often wash ashore. If you find an egg casing along the seashore, take a photo for Purse Search Ireland, a citizen science project focusing on monitoring the shark, ray and skate species around Ireland.

Another species also found by Irish scientists using the ROV Holland 1 in 2018 was a very rare type of dogfish, the Sail Fin Rough Shark, Oxynotus paradoxus. These sharks are named after their long fins which resemble the trailing sails of a boat, and live in the deep sea in waters up to 750m deep. Like all sharks, skates and rays, they have no bones. Their skeleton is composed of cartilage, much like what our noses and ears are made from! This material is much more flexible and lighter than bone which is perfect for these animals living without the weight of gravity.

Throughout history sharks have been portrayed as the monsters of the sea, a concept that science is continuously debunking. Basking sharks were named in 1765 as Cetorhinus maximus, roughly translated to the ‘big-nosed sea monster’. Basking sharks are filter feeders, often swimming with their mouths agape, they filter plankton from the water.

They are very slow moving and like to bask in the sun in shallow water and are often seen in Irish waters around Spring and early Summer. To help understand the migration of these animals to be better able to understand and conserve these species, the Irish Basking Shark Group have tagged and mapped their travels.

Remarkably, many sharks like the Angel Shark, Squatina squatina have the ability to sense electricity. They do this via small pores in their skin called the ‘Ampullae of Lorenzini’ which are able to detect the tiny electrical impulses of a fish breathing, moving or even its heartbeat from distances of over a kilometre! Angel sharks, often referred to as Monkfish have a distinctively angelic shape, with flattened, large fins appearing like the wings of an angel. They live on the seafloor in the coastal waters of Ireland and much like a cat are nocturnal, primarily active at night.

The intricate complexity of shark adaptations is particularly noticeable in the texture of their skin. Composed of miniscule, perfectly shaped overlapping scales, the skin of shark provides them with protection. Often shark scales have been compared to teeth due to their hard enamel structure. They are strong, but also due to their intricate shape, these scales reduce drag and allow water to glide past them so that the shark can swim more effortlessly and silently. This natural flawless design has been used as inspiration for new neoprene fabric designs to help swimmers glide through the water. Although all sharks have this feature, the Leafscale Gulper Shark, Centrophorus squamosus, found in Ireland are specifically named due to the ornate leaf-shape of their scales.
