A local community in eastern Co Mayo rallied to attempt to save as many as 13 common dolphins that live-stranded near Blacksod on Friday (13 August).

As Mayo IWDG’s Facebook reports, the family group comprising 13 dolphins — mainly mothers and calves with a large male — stranded at Tarmon Beach with the tide dropping.

Sadly three of the dolphins died before they could be helped, but the rest responded to being cooled with buckets of seawater by local volunteers assisting the area’s Irish Whale and Dolphin Group (IWDG) members.

As the tide was still dropping for over an hour, it was quickly decided to move the dolphins 2km by road to the slipway at Blacksod where they could be more easily immersed and cared for.

The local IWDG team used their new wheeled dolphin stretcher to transport the larger marine wildlife to a horse box, while the juveniles were carried in beach towels.

Once carefully released back into the water, all were seen to swim quickly and without obvious distress, and by 9pm the pod had left the area.

“Tarmon and the surrounding beaches on the east side of the Mullet Peninsula are notorious for common dolphins live-stranding due to the topography of the beaches,” Mayo IWDG said.

“The beaches are large flat expanses so during spring tides especially, the water can level can drop uniformly and recede up to 1km in parts. Common dolphins being an offshore dolphin species often get caught out on such difficult-to-navigate shallow terrain.

“When a dolphin live-strands it puts immense pressure on their bodies. They can become very disorientated and have muscle spasms from the stranding event making it difficult to swim, which is why this group were given recovery time at Blacksod before being released.

“Thanks again to everyone who helped out today; it was so humbling to see everyone work together to get this pod back to the sea.”

Elsewhere, the IWDG reports on two separate strandings of Sowerby’s beaked whales in Co Galway. The first was found washed up on Inisbofin at the end of the week while the second was reported yesterday (Saturday 14 August) across the water in Cleggan.

Commenting on the former report, the IWDG said: “Beaked whales are not stranded that frequently but this individual had evidence of rope marks on its body.

“As [they are] an offshore deep-diving species we don’t expect beaked whales to get entangled in fishing gear or interact with offshore activity.

“Maybe these rope marks were not from fishing but some other source. Hard to tell, but without a full post-mortem examination the cause of death will remain speculative.”

A Sowerby’s beaked whale — of a marine wildlife species rarely sighted in Irish waters — has died after getting into distress in Wicklow Harbour, as The Irish Times reports.

According to the Irish Whale and Dolphin Group (IWDG), the male whale stranded near Wicklow Sailing Club after losing its bearings yesterday morning, Saturday 4 July.

Sowerby’s beaked whales are one of four out of 22 beaked whale species known to be in Irish waters. They normally inhabit deep waters below 200 metres in the North Atlantic, and are rarely seen by humans.

“From the outset it appeared to be in poor health, appearing disorientated and having difficulty moving. Therefore, it would not have been a candidate for refloating,” the IWDG said in a statement on Facebook.

“Euthanasia is also extremely difficult in these circumstances due to the large size of the animal as well as public safety concerns.”

The whale will be recovered for a full post-mortem to try and “to find out more about the life of these rare and enigmatic whales”, said IWDG chief executive Dr Simon Berrow.

Ten months ago a Sowerby’s beaked whale stranded on a beach near Helvick Head in Co Waterford. While it was refloated twice by local lifeboat volunteers, it was thought unlikely to survive.

Concerns remain for the health of a rare beaked whale refloated from a Co Waterford beach at the weekend, as The Irish Times reports.

The Sowerby’s beaked whale stranded near Helvick Head on Friday (30 August) and was twice returned to the open sea by the local RNLI lifeboat crew.

The incident marks the fourth stranding this year around the coast — and the only live stranding — of a deep water marine wildlife species that’s historically been rare in Irish inshore waters, with only 25 confirmed since records began.

Its fate is currently unknown, but Irish Whale and Dolphin Group (IWDG) strandings officer Mick O’Connell suggests the situation doesn’t look good.

“Sowerbys usually live in much deeper water 300kms off the west coast — that makes me think it’s unlikely it will survive — it may be sick, but it’s got as good a chance to survive as it could because everything was done locally to get it back out to sea,” he said.

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.
