The Irish Whale and Dolphin Group has conformed the first validated sighting of a fin whale off Co Donegal.

Liz Morrow captured images of the solo large whale in Donegal Bay off Slieve League earlier this month, estimating it to be around 18 metres in length.

Fin whales are a common occurrence in Ireland’s South West and the Celtic Sea, but have never before been spotted in the inshore waters of the colder North West.

However, with the later sighting of a humpback whale breaching off Malin Beg, it could be a sign that larger marine wildlife are exploring new territory north of Sligo.

“Any large whales that simply look too large to be a minke or humpback and produce a powerful columnar ‘blow’ on surfacing, should be considered as likely candidates,” the IWDG suggests.

“They will often be accompanied by common dolphins who hunt the same sprat and herring shoals and they never lift their tails before diving.”

Suspected fin whales are best approached from the right side and photographed at the head and rostrum “which should reveal the diagnostic lower white right jaw”.

#MarineWildlife - Residents on Arranmore off the Donegal coast were surprised to find a rare whale carcass washed up on their island over the weekend.

According to BBC News, the 20-metre cetacean is believed to be a fin whale, an endangered species not normally spotted so close to Irish shores.

Though photo opportunities may be tempting, the public has been urged to stay away from the carcass for health and safety reasons.

Fin whales are sometimes spotted offshore, says Dave Wall of the Irish Whale and Dolphin Group (IWDG), who added that this whale was likely dead for some time before its carcass beached.

It’s not known what causes the fin whale’s death. But marine debris — especially microbeads from bathroom products – is a growing threat to all whales, dolphins and porpoise in Irish waters, as the IWDG recently reported.

Citing a new study that found marine debris (such as plastic bags and fish hooks) in the digestive tracts of 8.5% of cetaceans examined, the IWDG highlights that micro-plastics were present in the guts of every animal in the study.

“While larger marine debris has been shown to cause impaction of the gut and other complications which can lead to death, the impact of micro-plastic contamination is not known,” says the group.

“It is thought it can act as a vehicle for persistent pollutants, which adhere to the large surface area resulting in a potential increase in contaminant burdens in marine mammals.”

#MarineWildlife - Marine scientists have been puzzled by the recent beaching of a whale rarely seen off the east coast of England.

According to the Guardian, the carcass of a 12m fin whale washed up at Holkham in Norfolk last Thursday afternoon (20 October), far from its usual waters between Britain and Ireland.

“You never get them in the North Sea, so what it was doing there, we have no idea at the moment,” biologist Dr Ben Garrod told the newspaper.

It’s not yet known what causes the marine giant’s death, though collision with a vessel in the North Sea has been mooted as one possibility, as the Eastern Daily Press reports.

#MarineWildlife - Whale sightings are on the increase in the South East this week as the season tapers off, according to the Irish Whale and Dolphin Group (IWDG).

"As large whales don't keep to our calendar year, this annual south east flurry of large whale sightings represents the tail-end our our large whale season," says the IWDG's sightings officer Pádraig Whooley.

"And what a season it has been, especially for the humpback whale, which have enjoyed a record year both in terms of frequency of sightings since they first appeared in early May off the Slea Head Peninsula."

The latest spots were made both on land – by Andrew Malcolm and Ann Trimble from Ardmore Co in Waterford at the weekend – and on a whale-watching trip with Martin Colfer's South Coast Charter Angling, recording a humpback whale and more than five fin whales between them.

And there might still be time to head down to the Sunny South East to catch a glimpse of these ocean giants before they depart for the spring.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) has proposed a restriction of seismic survey activity on the slopes of the Irish continental shelf and the Porcupine Seablight.

The IWDG says its move "stems from an increasing body of evidence which indicates that the Irish Shelf Slopes and Porcupine Seablight are an important migration route and opportunistic foraging area for blue whales and fin whales from August to March each year.

"Humpback whales are also known to migrate along a similar route in the winter and early spring," it added in a statement.

The cetacean conservation charity as expressed concern at what it perceives as "a large increase in seismic survey activity in the Porpcupine Seablight during the main migration period and recent evidence of disturbance to these migrating whales by seismic surveys."

As a result, the IWDG has proposed to the Petroleum Affairs Division of the Department of Natural Resources that seismic surveys – such as that scheduled to be conducted in the Porcupine Basin this September – be "restricted to the months March to August, outside of the migration period, in order to minimise disturbance to these highly endangered whale species."

According to the group "similar measures" have been successful in other parts of the world, such as off South Africa, where whales "seasonally occur in large numbers".

#MarineWildlife - Late summer brings fin whales flocking to West Cork in big numbers, with the Irish Whale and Dolphin Group estimating at least 20 of the second-largest ocean species sighted between Seven Heads and Galley Head.

Indeed, as IWDG sightings officer Padraig Whooley writes, the gathering "is certainly the largest validated aggregation of this species so far this year" and comes some months ahead of the usual peak from October to December.

Recommended spots for watching these fin whale visitors - though you will need some decent binoculars to get the best views - are the aforementioned Galley Head and Seven Heads as eel as Cloghna Head, Dunworley and Sandscove.

Kerry has its own share of whale visitors, with a "lovely run" of humpbacks in recent weeks, while East Coast residents aren't left out, either, with a rare sighting of a minke whale in the Irish Sea some 20km off Bray Head over a week ago.

In other cetacean news, West Cork has become home to a new solitary dolphin in the form of Clet, a bottlenose who's been spotted in Glandore, Baltimore and Schull after time from Devon, Cornwall, South Wales and originally France.

Yet as IWDG welfare officer Paul Kiernan warns, Clet might appear cute but he's very much a wild animal, with reports claiming a swimmer off Sherkin Island was "aggressively pushed underwater by the dolphin".

Such stories, Kiernan writes, point "to the need for people to exercise common sense and extreme caution in how best to enjoy an interaction with this very large, apex predator."

He adds: "Bottlenose dolphins are not cute and cuddly, they are not our 'friends' and nor do they benefit in any meaningful or long term way from interacting with humans."

#MarineWildlife - The Irish Whale and Dolphin Group is reporting a "high volume of sightings" of minke whales - plus the odd fin whale - off the coasts of West Cork and Kerry as this week's heatwave continues to bask the country.

The first reports from the early part of the week showed a big increase of sightings and activity in the southwest region - but also off Mullaghmore, the popular surfing spot in Co Sligo, where as many as three minkes were spotted last weekend, and as far afield as Belfast Lough where several minke whales were photographed.

As the week progressed, the first confirmed sighting of a fin whale came in from Slea Head in Co Kerry in waters teeming with six minke whales and around 150 common dolphins.

And a whale watch trip of West Cork came into range of an amazing 12 minke whales, including a number of juveniles who seemed to make a game of swimming around the watchers' vessel.

The latest reports came in on Thursday from Baltimore and Clougher Head, which indicate that fin whales may be arriving here in big numbers. Here's hoping a few humpbacks will follow in their wake!

#MarineWildlife - Here's a little something cheerful to brighten up this chilly, snowy Monday morning: some video footage from YouTube shot by Irish Whale and Dolphin Group (IWDG) member Karl Grabe of the first whales to visit Ireland's shores in 2013.

As previously reported on Afloat.ie, the first sightings were made last week on the maiden member whale-watching trip on board the IWDG's new marine wildlife research vessel Celtic Mist off the coast of Wexford.

In addition to these fin whales, the group also made the acquaintance of a group of frolicking dolphins from the 'superpod' spotted in the Irish Sea recently, as you can see from the clip below:

#MarineWildlife - The whale watching season is well under way off the coast of Wexford, as the Irish Whale and Dolphin Group (IWDG) reported its first sightings of 2013 this week.

Just an hour into the maiden cetacean spotting voyage of the IWDG's new research vessel Celtic Mist at the weekend, members of the group were treated to the sight of fin whales and minke whales feeding south of Hook Head - not to mention some of the 'superpod' of dolphins seen last week in the Irish Sea.

And as World Irish reports, local wildlife ranger Tony Murray spotted the first humpback whale of the year in the same area.

Murray suggested that "a large herring haul going on in the southeast at the moment" is the main attraction for the ocean giants and their smaller, more plentiful companions.

The IWDG's Facebook page has a photo gallery containing some stunning snapshots of the day's excursion HERE.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) reports of another "frenzy of activity" while on a whale research cruise off West Cork this week.

The 'members only' trip on Wednesday 5 December took in the hotspot west of Reen Pier in Union Hall "where humpback and fin whales have enthralled hundreds of whale watchers and wildlife enthusiasts alike in recent weeks," according to IWDG sightings co-ordinator Pádraig Whooley.

When it soon became clear that most of the whales had left the area, the team headed east to return an ill member to shore.

"This turn of events proved almost karmic," says Whooley, "as not long after dropping our colleague back to Reen Pier, we started getting text messages from IWDG observers Tim Feen and Chris O'Sullivan of both humpback and fin whales well to the east on the Clonakilty Bay side of Galley Head."

Racing against the fading afternoon light, the boat made it to the scene to witness the blows first of fin whales, then humpbacks - at least five of the latter and seven of the former - and confirming them as the giants previously seen between the Kedge and Stags.

The team collected biopsy samples from most of the relaxed pod, including one that is suspected to be a female humpback with a calf.

"Since then, the weather has been very poor," says Whooley, "but there are still sufficient reports coming into IWDG to suggest to us that the large whale activity is slowly pushing east."

The IWDG is also collaborating with the BBC's WinterWatch programme next week, which is hoping to follow up on last year's AutumnWatch special on fin whales from East Cork and Waterford by filming humpback whales in West Cork.

Members of the public or whale-watchers are encouraged to report any sightings they might witness over the weekend to the IWDG by using the 'Report a sighting' link on the home page at iwdg.ie.

Dublin Bay

Dublin Bay on the east coast of Ireland stretches over seven kilometres, from Howth Head on its northern tip to Dalkey Island in the south. It's a place most Dubliners simply take for granted, and one of the capital's least visited places. But there's more going on out there than you'd imagine.

The biggest boating centre is at Dun Laoghaire Harbour on the Bay's south shore that is home to over 1,500 pleasure craft, four waterfront yacht clubs and Ireland's largest marina.

The bay is rather shallow with many sandbanks and rocky outcrops, and was notorious in the past for shipwrecks, especially when the wind was from the east. Until modern times, many ships and their passengers were lost along the treacherous coastline from Howth to Dun Laoghaire, less than a kilometre from shore.

The Bay is a C-shaped inlet of the Irish Sea and is about 10 kilometres wide along its north-south base, and 7 km in length to its apex at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south. North Bull Island is situated in the northwest part of the bay, where one of two major inshore sandbanks lie, and features a 5 km long sandy beach, Dollymount Strand, fronting an internationally recognised wildfowl reserve. Many of the rivers of Dublin reach the Irish Sea at Dublin Bay: the River Liffey, with the River Dodder flow received less than 1 km inland, River Tolka, and various smaller rivers and streams.

Dublin Bay FAQs

There are approximately ten beaches and bathing spots around Dublin Bay: Dollymount Strand; Forty Foot Bathing Place; Half Moon bathing spot; Merrion Strand; Bull Wall; Sandycove Beach; Sandymount Strand; Seapoint; Shelley Banks; Sutton, Burrow Beach

There are slipways on the north side of Dublin Bay at Clontarf, Sutton and on the southside at Dun Laoghaire Harbour, and in Dalkey at Coliemore and Bulloch Harbours.

Dublin Bay is administered by a number of Government Departments, three local authorities and several statutory agencies. Dublin Port Company is in charge of navigation on the Bay.

Dublin Bay is approximately 70 sq kilometres or 7,000 hectares. The Bay is about 10 kilometres wide along its north-south base, and seven km in length east-west to its peak at the centre of the city of Dublin; stretching from Howth Head in the north to Dalkey Point in the south.

Dun Laoghaire Harbour on the southside of the Bay has an East and West Pier, each one kilometre long; this is one of the largest human-made harbours in the world. There also piers or walls at the entrance to the River Liffey at Dublin city known as the Great North and South Walls. Other harbours on the Bay include Bulloch Harbour and Coliemore Harbours both at Dalkey.

There are two marinas on Dublin Bay. Ireland's largest marina with over 800 berths is on the southern shore at Dun Laoghaire Harbour. The other is at Poolbeg Yacht and Boat Club on the River Liffey close to Dublin City.

Car and passenger Ferries operate from Dublin Port to the UK, Isle of Man and France. A passenger ferry operates from Dun Laoghaire Harbour to Howth as well as providing tourist voyages around the bay.

Dublin Bay has two Islands. Bull Island at Clontarf and Dalkey Island on the southern shore of the Bay.

The River Liffey flows through Dublin city and into the Bay. Its tributaries include the River Dodder, the River Poddle and the River Camac.

Dollymount, Burrow and Seapoint beaches

Approximately 1,500 boats from small dinghies to motorboats to ocean-going yachts. The vast majority, over 1,000, are moored at Dun Laoghaire Harbour which is Ireland's boating capital.

In 1981, UNESCO recognised the importance of Dublin Bay by designating North Bull Island as a Biosphere because of its rare and internationally important habitats and species of wildlife. To support sustainable development, UNESCO’s concept of a Biosphere has evolved to include not just areas of ecological value but also the areas around them and the communities that live and work within these areas. There have since been additional international and national designations, covering much of Dublin Bay, to ensure the protection of its water quality and biodiversity. To fulfil these broader management aims for the ecosystem, the Biosphere was expanded in 2015. The Biosphere now covers Dublin Bay, reflecting its significant environmental, economic, cultural and tourism importance, and extends to over 300km² to include the bay, the shore and nearby residential areas.

On the Southside at Dun Laoghaire, there is the National Yacht Club, Royal St. George Yacht Club, Royal Irish Yacht Club and Dun Laoghaire Motor Yacht Club as well as Dublin Bay Sailing Club. In the city centre, there is Poolbeg Yacht and Boat Club. On the Northside of Dublin, there is Clontarf Yacht and Boat Club and Sutton Dinghy Club. While not on Dublin Bay, Howth Yacht Club is the major north Dublin Sailing centre.
