#DolphinDeaths - Hundreds of bottlenose dolphins have died in strandings along the east coast of the United States this summer - and a measles-like virus could be to blame.

As The Irish Times reports, the National Oceanic and Atmospheric Administration (NOAA) is currently investigating the extraordinary die-off, which has been tentatively connected to morbillivirus, an immune system suppressor similar to the virus that causes human measles.

In numbers not seen since the late 1980s, as many as 333 dolphin carcasses have been found on the shoreline between New York and North Carolina, more than 10 times the average for this time of year.

Researchers from universities and marine institutes are concentrating on the Virginia coastline, where the majority of the dead cetaceans have been found, and believe they have identified evidence of morbillivirus in nearly all sampled carcasses.

Wired Science says scientists do not yet know what caused the outbreak, though they speculate that dolphins may simply have lost their natural immunity to the virus since the last attack.

And according to the NOAA's Teri Rowles: “At this point, there isn’t anything to stop the virus.”

As of yet there are no indications if the virus could migrate to dolphin populations on this side of the Atlantic, particularly in the designated cetacean sanctuary of Irish waters.

#Fishing - The Marine Institute is encouraging the agreement of a new code of practice for oyster fishing at Ballinakill Bay in Co Galway, which is set to lose its disease-free status.

Galway Bay FM reports that a single oyster out of 900 tested at the bay, near Letterfrack on the north-west coast of Connemara, tested positive for the Ostreid herpes virus two years ago as part of an EU-supported programme.

Though accounting for just 0.11% of the entire sample, the positive test is enough to strip the area of its clean status.

Senator Trevor O'Clochartaigh raised the issue in the Seanad last week, which prompted the Department of the Marine to confirm that the Marine Institute recommends a code of practice that would see the area's status eventually reinstated.

#MARINE WILDLIFE - Some 46 reports of stranded whales and dolphins in Northern Ireland are among the thousands recorded across the UK over the last six years, according to BBC News.

A new study co-ordinated by the Zoological Socoety of London (ZSL) shows that some 3,500 cetaceans were stranded on the British coastline between 2005 and 2010.

Though year-on-year figures have fallen overall, is presumed that many more strandings have gone undetected.

Many were found to have died of disease or starvation – particular harbour dolphins.

But human activity such as fishing, shipping and chemical pollution also poses a significant threat to marine wildlife in the waters around the British Isles, said Rob Deaville of the ZSL.

The public is being encouraged to report stranded marine mammals to help create a more accurate picture.

Experts in the United States are investigating the possibility of a disease outbeak as the number of dead seals found on New England beaches continues to grow.
The Gloucester Times in Massachusetts reports that some 128 harbour seals have been found deceased this year along the coastline from Massachusetts to Maine.
Initial results from post-mortems carried out on 10 harbour seals washed up in northern Massachusetts indicate no direct human involvement, and also ruled out physical attacks or effects of fishing.
All the dead seals are reportedly young and healthy, with enough body fat to rule out starvation.
"We have collected biological samples and are looking at potential biological toxins," said a spokesperson for the National Oceanic and Atmospheric Administration. "At this point we aren't ruling anything out."
It's believed that the marine wildlife casualties are unrelated to the recent discovery of seven dead seals in Donegal, due to the distance between the incidents and the difference in species.

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.
