#whale – A marine biologist who attempted to cut open a dead Sperm Whale beached in the Faeroe islands last Tuesday (November 26) narrowly escaped being dosed in entrails when the poor dead creature exploded.

A video clip, shown on Faroese Television, showed a washed-up dead sperm whale explode, spraying entrails. The dead whale had been lying on the beach for two days after it got stuck in waters between the Faroe Islands' two biggest islands. On Tuesday, marine biologist Bjarni Mikkelsen was dispatched to cut it open. As he did so, the whale exploded - the explosion being the result of methane gas accumulating during the dying process.

Laast October in Baltimore, West Cork a whale carcass cretaed a 'Rancid Oil Slick' in a conservation area off the south west coast of Ireland after it died in the Baltimore harbour and was towed offshore.

#MarineScience - An American university is teaming up with marine experts in Dingle to offer advanced marine biology classes.

As the Fairfield Sun reports, the biology department at Sacred Heart University in Connecticut is collaborating with scientists and staff at the Dingle Oceanworld Aquarium to offer the advanced classes to undergraduate and postgraduate students alike, beginning this May.

It's expected that the Coastal Study Centre programme will eventually provide both semester-long and short courses to take advantage of the aquarium's advanced research facilities, and will also accommodate students doing relevant thesis field work.

“Very few primarily undergraduate institutions have as strong a coastal focus as Sacred Heart does, which is only enhanced by our proximity to Long Island Sound,” said John Rapaglia, assistant professor of biology at Sacred Heart.

Dingle Harbour’s semi-rural to rural location creates a nice juxtaposition to the highly urbanised Long Island Sound.”

Sacred Heart already has an established campus in the Kerry Gaeltacht town where students can take classes on Irish and Celtic history and heritage among other subjects.

#MARINE WILDLIFE - Work on exterminating sea squirts at a marina in north Wales has begun.

The £250,000 (€301,000) project by the Countryside Council for Wales involves attaching giant bags to the subsurface structures around the marina in Holyhead, which is hoped will stop the clean flow of water to the sea squirts, causing them to suffocate and die.

Marine biologist Rohan Holt, who is managing the project, said: “If we successfully eradicate the sea squirt, we will work hard to make sure that it does not recolonise.

"This will mean careful monitoring in Holyhead marina and other marinas and popular mooring areas throughout Wales to check that it hasn’t reappeared."

The sea creature threatens shellfish by spreading like a blanket across the seabed and other surfaces.

As previously reported on Afloat.ie, colonies of the invasive Japanese sea squirt are posing a throat to mussel and scallop bed in the Menai Strait between Anglesey and the mainland.

Boats from Ireland have been blamed for carrying the invasive pest into Holyhead.

Time may be running out for Scotland's only resident pod of killer whales, the Scotsman reports.
The four males and five females have been studied at their home in the west of Scotland by the Hebridean Whale and Dolphin Trust and the Irish Whale and Dolphin Group for almost 20 years.
The marine mammals have been sighted at various times since 1981 by members of the public in Scotland, Wales and Ireland.
But since 1992 the group - known as the West Coast Community - has failed to produce a single surviving calf.
Marine biologist Dr Andy Foote said: "It's probably too late to save this group. I do believe that they will become extinct in our lifetime which is very regrettable since not many people even know that such a distinctive group of killer whales exist just off our coast."
Dr Foote believes possible contaminants in the waters off Scotland's west coast could be one reason why the pod is not successfully breeding.

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.
