#MarineWildlife - Conservationists want Tralee Bay and Brandon Bay in North Kerry to be declared a protected marine wildlife zone for bottlenose dolphins.

The call comes in the wake of new research by the Irish Whale Dolphin Group (IWDG) in tandem with the Shannon Dolphin and Wildlife Foundation, which has identified the vast majority of bottlenose dolphins in North Kerry as members of the Shannon Estuary group that has enjoyed Marine Protected Area status since 2000.

“We knew dolphins had been regularly observed in Brandon Bay,” said the IWDG’s Dr Simon Berrow of the new research, “but did not know which population they belonged to and had no idea they were as abundant and frequent as this study has shown.”

Stephanie Levesque, senior author of the study, added that the research identified “very high numbers of Shannon dolphins present during the summer months in Brandon and Tralee Bays.

“If further surveys were to be carried out at various times of the year, including collecting behavioural data, it could help us to better understand how they are using these habitats.”

Elsewhere on the West Coast, Galway Bay FM reports on efforts in Connemara to form local groups in Oughterard and Letterfrack which are designated for the protection of pearl mussels.

#MarineWildlife - The RSPB has welcomed the announcement of new marine protected areas for Northern Ireland this week.

“The formal designation of four new marine protected areas will help protect a range of vulnerable species and habitats - ranging from black guillemots to ocean quahog and seagrass meadows,” the wildlife charity said in a statement.

Among the new Marine Conservation Zones (MCZs) announced by Storming is an area near Rathlin Island off Co Antrim that’s the first in the UK to be set aside for a seabird species, the amber-listed black guillemot.

The other new zones announced include seagrass meadows in Waterfoot, also in Co Antrim, and the fragile ecosystem for sea pens in Carlingford Lough.

Also included among the new MCZs is the territory of ocean quahogs in outer Belfast Lough.

According to The Irish News, these clams are thought to have been thriving in the waters near the city for over 200 years - and individual clams could live for hundreds more.

The Stormont announcement comes a year after the new zones were first proposed for public consultation, as previously reported on Afloat.ie.

#MarineWildlife - The first meeting of the Irish Whale and Dolphin Group’s (IWDG) new local group for North Kerry takes place this Friday 9 December at the Tralee Bay Wetlands Centre from 7.30pm to 9pm.

All are welcome to the evening’s talk by biologist Dr Marie Louis on her work on bottlenose dolphins in Ireland and internationally, followed by a meeting on setting up the new group.

The North Kerry group’s main focus is to get local people out experiencing and recording cetaceans and collecting data for the IWDG, as well as increasing membership numbers. Contact [email protected] for more information.

In other news, Conal O’Flanagan has been appointed to the IWDG’s board of directors, replacing regular Celtic Mist helm Karl Grabe.

O’Flanagan joined the IWDG soon after its formation in 1999 and was the first co-ordinator of its Constant Effort Sighting Scheme. The resident of North Co Dublin has previously been a director on the board and served as group treasurer.

#MarineWildlife - Is cannibalism among seals to blame for deaths of the marine mammals recorded on Ireland’s shores?

That’s one reason suggested by researchers in the latest report from the Irish Seal Sanctuary’s seal death database, according to the Irish Examiner.

While further research is required, recent studies at UCD indicate that some injuries previously attributed to boat propellers may be consistent with attacks on younger seals by older bulls.

Fishing activity is also suspected in some of the more than 100 carcasses recorded in the two years before May 2016 — particularly over the winter months in Waterford and Wexford, though there is no confirmed connection to the concurrent inshore fishery.

The sanctuary’s database relies on public contributions, with the largest number of seal carcasses reported in Dublin, followed by Cork, Wexford and Waterford.

In related news, the Dublin InQuirer reports on the uneasy relationship between dog walkers on Bull Island and the reserve’s resident seal colonies, which conservationists argue are often disturbed by pets running loose.

#MarineWildlife - The Irish Whale and Dolphin Group (IWDG) received a report at the weekend of a large baleen whale struggling in the shallows at Cross Beach in north-west Co Mayo.

The 12-metre marine mammal, thought to be a sei whale or fin whale, was ushered back into deeper waters by a group surfing in the area on Sunday 27 November.

But locals are urged to keep a lookout over the next few days as the whale, believed to be injured or in poor health, is likely to strand again.

#MarineWildlife - A small Norwegian community in the Arctic Circle recently had a whale of a problem with their internet connection - literally.

As New Scientist reports, a subsea internet cable in the Kaldfjorden north of Tromsø which should have been 170m below the surface broke loose from the fjord bed and entangled one of its many humpback whale visitors for more than a day.

Believing at first that the marine giant was caught in fishing gear, rescuers discovered after finally freeing the whale that it had been caught in a data cable - hence the affectionate nickname ‘Hacker’.

New Scientist has more in the story HERE.

#MarineWildlife - Irish-made documentary The Humpback Whales of Cape Verde will be broadcast this Saturday 29 October at 7.15pm on TG4.

Narrated by Liam Ó Maonlaí and shot in Cape Verde, Ireland and Malta, the film follows Dr Simon Berrow of the the Irish Whale and Dolphin Group (IWDG) and an international team of marine scientists on an ambitious adventure to prove humpback whales from both the northern and southern hemispheres use the Cape Verde archipelago as a breeding ground.

“If we could make the connection, our understanding of humpback whale behaviour in the Atlantic would change,” says Dr Berrow. “Such a breeding ground would be unique. But going there in the first place at that time of year and at significant cost was a big if in itself.”

The lecturer at GMIT also believes the film will help highlight the importance of conservation in Irish waters.

“It still comes as a surprise to many that we have whales in Ireland,” he says. “In fact the numbers here are increasing each year and Ireland is becoming internationally important.

“To understand where whales in Ireland are coming from or going to and breeding is essential to protect them. This film is part of a 12-year search for the breeding grounds of humpback whales in Ireland.”

The broadcast on TG4 this weekend coincides with the 25th anniversary of all Irish waters being declared a whale and dolphin sanctuary, the first of its kind in Europe.

“It is an international story with an Irish perspective,” says director Tony Whelan. “It’s a cracking tale. Spending time with these scientists in an extraordinary environment was a privilege. We hope people enjoy it.

“We are really happy it has been taken up by TG4, an important channel for independent filmmakers. Without them stories like this can go unseen.”

The Humpback Whales of Cape Verde was screened around the country earlier this year as part of a library tour, as previously reported on Afloat.ie.

#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 - Independent.ie has video of a seal pup being rescued by quick-thinking beachgoers in Co Down this week.

Aaron McLoughlin realised he had no phone signal to call for assistance when he and his wife Gemma and her family found the young seal stranded on the sand.

So he and his father-in-law David Lamont improvised a sling to lift the juvenile marine mammal out of danger and back into the water, as you can see in the clip below:

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.
