#MarineWildlife - Marine wildlife welfare groups will received €27,000 out of more than €2.5 million awarded to 140 animal welfare organisations nationwide by the Department of Agriculture, Food and the Marine.

Seal Rescue Ireland, based at Courtown Harbour in Co Wexford, will receive €12,000, while €5,000 apiece will go to Galway & Claddagh Swan Rescue, the Irish Seal Sanctuary in Garristown, Co Dublin and the Irish Whale and Dolphin Group in Kilrush, Co Clare.

Making the announcement at the Irish Blue Cross Clinic in Inchicore on Friday 18 December, Marine Minister Simon Coveney said that these organisations "make a tremendous contribution to the welfare of animals, in particular, by educating the public on best practice, by making effective interventions where appropriate and providing facilities for at-risk animals.

"The increase in workload for animal welfare bodies due to new animal welfare legislation, including the new dog microchipping legislation, and the continuing albeit decreasing reporting of incidences of animal neglect to the department’s animal welfare helpline, clearly demonstrates a need to assist animal welfare organisations in their important work.

"I am pleased therefore to be in a position to increase funding to animal welfare organisations for the fifth consecutive year."

The minister added that he and his department would continue to work closely with animal welfare groups. He reminded the public of the dedicated email address ([email protected]) and helpline (01 607 2379 or Call Save 0761 064408) in operation in the Department of Agriculture, Food and the Marine for members of the public to report incidents of animal cruelty. The helpline will be monitored regularly over the holiday period.

#MarineScience - Climate change is rapidly warming lakes around the world, threatening freshwater supplies and ecosystems, according to a new study spanning six continents.

More than 60 scientists took part in the research, published in the journal Geophysical Research Letters and announced at the fall meeting of the American Geophysical Union on Wednesday 16 December.

The study – based on global analyses including unique long-term data from the Marine Institute's catchment research facility at Newport, Co Mayo – found that lakes are warming an average of 0.34C, or 0.61F, each decade.

That's greater than the warming rate of either the oceans or the atmosphere, and it can have profound effects, the scientists say.

At the current rate, algal blooms – which can ultimately rob water of oxygen – are projected to increase 20 percent in lakes over the next century. Algal blooms that are toxic to fish and animals would increase by five percent.

These rates imply that emissions of methane, a greenhouse gas 25 times more powerful than carbon dioxide, will increase four percent over the next decade.

"Lakes are important because society depends on surface water for the vast majority of human uses," said co-author Stephanie Hampton, director of Washington State University's Center for Environmental Research, Education and Outreach.

"Not just for drinking water, but manufacturing, for energy production, and for irrigation of our crops. Protein from freshwater fish is especially important in the developing world."

Temperature is one of the most fundamental and critical physical properties of water. It controls a host of other properties that include intricate living processes that have evolved within strict boundaries.

When the temperature swings quickly and widely from the norm, life forms in a lake can change dramatically and even disappear.

"These results suggest that large changes in our lakes are not only unavoidable, but are probably already happening," said lead author Catherine O'Reilly, associate professor of geology at Illinois State University.

Earlier research by O'Reilly has seen declining productivity in lakes with rising temperatures.

Funded in part by NASA and the National Science Foundation, the study is the largest of its kind and the first to use a combination of long-term hand measurements and temperature measurements made from satellites, offsetting the shortcomings of each method.

Study co-author Simon Hook, science division manager at the NASA Jet Propulsion Laboratory, said satellite measurements provide a broad view of lake temperatures over the entire globe. But they only measure surface temperature, while hand measurements can detect changes in temperature throughout a lake. Also, satellite measurements go back only 30 years while some lake measurements can go back more than a century.

Lough Feeagh in Co Mayo was one of 235 lakes in the study that have been monitored for at least 25 years. While that's a fraction of the world's lakes, they contain more than half the world's freshwater supply.

The Marine Institute measures the surface water temperature of Lough Feeagh as part of the long term ecological monitoring of the Burrishoole catchment. The Burrishoole research station is an internationally important index site for diadromous fish monitoring, and water temperature is a crucial variable controlling growth, migration and survival of salmon, trout and eel in the catchment.

"The inclusion of data from Lough Feeagh in this study highlights the value of collecting local environmental long term data to inform global analyses," said Dr Elvira de Eyto, a biologist at the Marine Institute facility in Burrishoole and one of the studies co-authors.

Marine Institute chief executive Dr Peter Heffernan added: "The sharing of such data with global scientific networks makes an important contribution to worldwide climate change analyses, and our understanding of how the warming climate will affect our valuable aquatic resources."

The surface water of Lough Feeagh has warmed at a rate of 0.35C per decade between 1985-2009, although the rate of warming was lower than some other northern hemisphere lakes.

"We want to be careful that we don't dismiss some of these lower rates of change," said Hampton. "In warmer lakes, those temperature changes can be really important. They can be just as important as a higher rate of change in a cooler lake."

The researchers said various climate factors are associated with the warming trend. In northern climates lakes are losing their ice cover earlier, and many areas of the world have less cloud cover, exposing their waters more to the sun's warming rays.

Many lake temperatures are rising faster than the average air temperatures. Some of the greatest warming is seen at northern latitudes, where rates can average 0.72C, or 1.3F, per decade.

Warm-water, tropical lakes may be seeing less dramatic temperature increases, but increased warming of these lakes can still have large negative impacts on fish. That can be particularly important in the African Great Lakes, home to one-fourth of the planet's freshwater supply and an important source of fish for food.

In general, the researchers write: "The pervasive and rapid warming observed here signals the urgent need to incorporate climate impacts into vulnerability assessments and adaptation efforts for lakes."

#MarineWildlife - Four new Marine Conservation Zones (MCZs) for Northern Ireland have been put forward for consultation, as the Coleraine Times reports.

Rathlin, Waterfoot, Outer Belfast Lough and Carlingford Lough are the proposed locations, variously home to marine species from the black guillemot to the white sea slug, as well as vulnerable geomorphological features like sea arches.

"We all have a stake in preserving and protecting our marine environment for future generations so I urge people to let us know their views on these proposed sites and species," said NI Environment Minister Mark Durkan, who launched the consultation today (Monday 14 December).

Members of the public in Northern Ireland have until 11 March 2016 to express their views, with full details on the consultation available online.

#MarineWildlife - 'Poison Ivy' the seal pup is now in good hands after she was found on the streets of Galway by council workers earlier this month.

As the Galway Independent reports, the young seal was discovered on the footpath in Salthill by litter collectors and was cared for locally by vets, members of the public and volunteers with Galway & Claddagh Swan Rescue.

She has since been transferred to the Seal Rescue Ireland sanctuary in Wexford, where she is said to be thriving after treatment for dehydration and malnourishment, an eye infection and a number of infected wounds.

It's thought that since she still had half of her lanugo fur coat, she was less than three weeks' old when found – "so there is a good chance that little Poison Ivy was separated from her mom too early," said the sanctuary's manager Meadow Greenwood.

As for the name? It's part of a comic book theme at the sanctuary, which earlier in the year played host to the like of Blackbird, a seal rescued in Co Louth, and Mystique from Co Mayo, according to the Gorey Guardian.

In other marine wildlife news, there has been anger in Northern Ireland after an otter was found killed in a trap on a riverbank in Co Antrim last weekend.

According to the Belfast Telegraph, the PSNI is investigating the incident on the banks of the Sixmilewater River at Dunadry as the placement of the trap "suggests a deliberate attempt to target the otter" – a protected species at EU level.

And as a member of the Antrim and District Angling Association alleges, whether or not the trap itself is legal is irrelevant as its placement was not.

"There is a residential development backing onto that area ... A cat or a dog or a young child could have been caught in that trap."

#MarineWildlife - On Monday 7 December, Ireland today joined with a number of other countries in a demarche to the government of Japan about its whaling activities.

The demarche expresses “serious concern” at Japan's decision to resume whaling in the Southern Ocean under what it calls its “New Scientific Research Whale Programme in the Antarctic Ocean (NEWREP-A)”.

The demarche recalls the decision of the International Court of Justice in 2014 which held that Japan’s previous Southern Ocean whaling programme was not “for purposes of scientific research” under the International Convention for the Regulation of Whaling 1946 and was therefore unlawful.

The countries participating in the demarche note that the last Annual Meeting of the Scientific Committee of the International Whaling Commission held in June 2015 was unable to confirm that Japan had done enough to justify commencement of lethal sampling in the 2015/16 season.

In expressing concern to Japan, Ireland and the other participating countries urge the government of Japan as a member of the International Whaling Commission to respect the commission’s procedures, stress that there is no scientific basis to include lethal methods in NEWREP-A, and strongly request the government of Japan not to engage in this whaling programme.

Other member states of the EU and New Zealand also participated in the joint demarche.

#Whaling - Japan is set to resume whaling for minke whales off Antarctica in the new year in spite of a ruling by the International Court of Justice banning such activity.

According to BBC News, Japan says it has taken the court's decision into consideration – and maintains that it will only resume whaling in the Southern Ocean for "scientific" purposes.

But Australia, which won its case against Japan at the International Court of Justice in 2014, has restated its opposition to the move, with the country's environment minister Greg Hunt saying: "We do not accept in any way, shape or form the concept of killing whales for so-called 'scientific research'."

As previously reported on Afloat.ie, Irish marine research was cited by an expert panel at the International Whaling Committee that struck down Japan's 'scientific whaling' plan for lacking detail to determine how many minke whales would be hunted and for what exact purpose.

#MarineWildlife - Airborne drones will soon be used to patrol stretches of the Australian coast popular with Irish emigrants and holidaymakers that have seen numerous great white shark attacks over recent months.

According to BBC News, the New South Wales government will deploy drones with GPS and cameras providing a live feed to operators who can recommend action to close beaches to bathing and watersports as necessary.

The drones will work in tandem with a 'smart' drum line that will alert officials on the shore as soon as a shark is snagged on its baited hooks.

"We are delivering on a commitment to test the best science available, including new technologies, as we try to find a long term-term solution to keep our beaches safe," said NSW minister for primary industries Niall Blair.

#MarineWildlife - Two pilot whales suffocated after getting fish stuck in their blowholes – the first known record of such happenings since in over 400 years.

According to New Scientist, both whales met their end a year ago while their pod was hunting for flatfish in the waters between the UK and Belgium.

Examination of a carcass that washed up in the Netherlands six weeks after the pod was spotted revealed that its blowhole, necessary for breathing, was blocked by a common sole.

When the same thing was found in another dead pilot whale a few weeks later, researcher Lonneke IJsseldijk couldn't believe her eyes.

“When I got to the beach the second time, I saw this tail sticking out of the blowhole and I thought: ‘No way!’”

Flatfish are not the usual diet for deepwater cetaceans like the pilot whale, which normally feeds on cephalopods, but it's thought they may have had to adapt their diet in shallower seas.

It's not known what brought the pod so far from their usual North Atlantic haunts, though climate change may be a factor.

Unfortunately for these whales, the common sole is not so easily consumed, and their efforts to escape the whales may have caused their much larger predators' demise.

New Scientist has much more on the story HERE.

Pilot whales are regular visitors to Ireland's western shores, but strandings are not unusual either, with five whales dying after a mass stranding by a 13-string pod in Donegal in July 2014.

More recently, a trio of pilot whales were refloated after stranding in West Kerry this past August.

#MarineWildlife - A Dublin couple on a whale-watching tour off Queensland recently had to content with an attention-seeking humpback whale as they posed for a photo, as the Irish Post reports.

But the holidaying pair Declan and Mandy O’Donoghue seemed happy enough to share the spotlight with the marine giant as it slapped a fin on the waves behind them.

#ORCAoceanWatch - A marine mammal conservation initiative that took place in the summer, supported by the Isle of Man Steam Packet Company, proved a huge success in its first year.

The Steam Packet Company was one of 13 ferry, cruise, freight and naval organisations which assisted the inaugural ORCA OceanWatchWeek (previously reported on Afloat.ie) by welcoming volunteers on board to conduct surveys during sailings.

In July and August, volunteer marine mammal surveyors travelled on Ben-My-Chree to record sightings of marine mammals as they sailed across the Irish Sea between Douglas and Heysham.

The team enjoyed excellent weather conditions for surveying and spotted a minke whale and a grey seal during one crossing.
ORCA Community Wildlife Officer Anna Bunney said: ‘ORCA OceanWatch 2015 was a fantastic success; 16 different whales, dolphins and porpoises (collectively known as cetaceans) were sighted in seven European sea regions, which is an outstanding result. This provided ORCA with a snapshot of the cetaceans that can be sighted right on our doorstep, as well as highlighting the need for their conservation.

‘We’d like to thank the Steam Packet Company for its participation and support in the inaugural year of ORCA OceanWatch. We’re all extremely excited for ORCA OceanWatch 2016.’

Steam Packet Company Chief Executive Mark Woodward added: ‘We have supported surveys of marine life in the Irish Sea for many years, and were pleased to play our part in the ORCA OceanWatch initiative.

‘Protection of our marine environment is vital, and conducting regular surveys like these provide important information to help conserve and protect marine mammals.’

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.
