Update Friday 4 October: RTÉ News is now reporting that the whale, now identified as a 25ft fin whale and believed to be a juvenile, was found dead in Dublin Port this morning.

RTÉ News reports on a suspected whale sighting at Dublin Port this afternoon (Wednesday 2 October).

The 20-foot whale, estimated to be some 20 feet in length, was filmed blowing from its blowhole numerous times while swimming near the Stena berth.

Cetaceans rarely make appearances in the city. In November last year a common dolphin brightened a dreary winter’s day for city centre commuters when it swam as far as the Loopline Bridge.

Elsewhere, humpback whales have now been sighted in Donegal Bay, much further north than their usual haunts off the Cork and Kerry coasts.

The Irish Whale and Dolphin Group (IWDG) says records from the 22 and 24 September respectively represent the first for humpbacks in the area since the summer of 2008.

#MarineWildlife - The UK’s Natural History Museum has made available for the first time a vast trove of whale and dolphin stranding records in British and Irish waters.

The data covers the years 1913 to 1989, filling in a significant gap before the Irish Whale and Dolphin Group’s stranding scheme began in 1991.

Over the years many entries were submitted by the coastguard, fishermen and members of the public — including a detailed record of a harbour porpoise found in Co Cork in 1913, the very first card in the data set.

PhD candidate Ellen Coombs is combing through the records to determine what picture “one of the longest systematic cetacean stranding data sets in the world” reveals for the status of cetacean species in our waters.

And already there have been some important finds, such as occasional records of deep-diving Cuvier’s beaked whales over the decades — not to mention a double stranding of narwhals in 1949.

The data also correlates with already known trends, such as the sharp decline in blue whale records with the expansion of commercial whaling in the early 20th century.

#MarineWildlife - Unusual weather for this time of year may be responsible for a recent spate of whale and dolphin strandings on the Cork coast in the past week.

The Irish Examiner reports that among the eight strandings were the carcass of a sperm whale on Long Strand in West Cork and a dolphin with fishing line around its beak in Schull.

However, the Irish Whale and Dolphin Group’s (IWDG) Mick O’Connell said that while the statistic was high within such a short timeframe, it was not necessarily a mystery.

“We normally get the same thing every year,” said the IWDG stranding officer. “It is usually more in the southwest and west, but this year, I suppose we have had more southeast winds, which probably explains it.”

O’Connell added that the strandings are “only a percentage of what is actually dead at sea” — and that post-mortems may “shed some light in their deaths”.

#MarineWildlife - Naval Service personnel on patrol with the LÉ Samuel Beckett encountered the carcass of a large whale some 50 nautical miles south-east of Ballycotton Lighthouse in the days after Christmas.

The “mystery whale” is neither a sighting (which only counts or living cetaceans) nor a stranding. But as the Irish Whale and Dolphin Group (IWDG) says, the encounter “serves to remind us that the animals that wash up on our shoreline may represent only a small percentage of the total number of cetaceans that expire at sea of presumably natural causes.”

IWDG sightings officer Pádraig Whooley said the location of these whale remains was “interesting as this area of the Celtic Sea has produced the most consistent large-whale sightings in recent months, with fairly regular sightings of fin whales from land-based sites between Ram Head, Ardmore extending east towards the Hook Head lighthouse.”

The Beluga whale — a species mainly found in the Arctic Circle — has been recorded in Irish territorial waters as part of a groundbreaking three-year research project into our offshore habitats for marine wildlife.

On Friday (23 November) the ObSERVE Programme team announced the findings of its aerial and acoustic projects, led respectively by UCC and GMIT and which survived larked areas of the Irish and Celtic seas as well as the Atlantic Margin.

Besides the begula, the researchers detected endangered blue whales underwater up to 200km from their survey position, noting strong seasonal patterns in their sounds.

The most abundant baleen whale species is the minke whale, whose numbers in Irish waters reach some 12,000 in summer months and 5,000 in winter, including significant sightings of calves.

Fin whales were also recorded throughout the year, suggesting the continental slope and adjacent deep waters are an important area for this species.

Numbers of deep-water beaked whales — recently the subject of concern over mass strandings in Ireland and Scotland — were also estimated to reach some 4,000 in winter months.

In addition the ObSERVE Programme studied distribution and behaviour of dolphin species, as well as the half a million seabirds of the Atlantic Margin — which included sightings of white-tailed tropicbirds normally found much further south.

The news comes just days after a rare spotting of killer whales in pair off the coast of Co Dublin — and as hundreds of translucent parasitoid phronima have washed up on a beach near Dingle, as TheJournal.ie reports.

#MarineWildlife - Two common seals were released off the North Coast last week after being nursed back to health at the Exploris aquarium in Portaferry.

According to The Irish News, the seals named Hans and Albert had been with the sanctuary since the summer, when they arrived with various injuries.

However, by September both had put on weight and were eating by themselves, prompting Exploris staff to plan for their eventual release at Ballintoy Harbour last Wednesday (29 November).

In a techy twist, Hans and Albert have been microchipped so their progress can be monitored from shore over the next few weeks and months.

Also in the care of Exploris staff is a baby seal rescued from a rocky outcrop off Bangor in Belfast Lough in late October.

BBC News has video of the tiny white seal pup, which was suspected to have an injured hip and damaged flipper likely suffered during Storm Ophelia.

Another presumed victim of the stormy weather was a seal recovered from Dun Laoghaire’s East Pier on Hallowe’en.

The Irish Times reports that the marine mammal had sustained injuries to its face and rear flipper, but was said to be doing well in the care of volunteers from the Courtown Seal Rescue Centre in Co Wexford.

More recently, a number of stranded dolphins were successfully returned to the water off Achill Island by locals and volunteers on Tuesday 21 November.

Four common dolphins were reflected from Keem Beach, though a fifth was found dead on nearby rocks. The Irish Whale and Dolphin Group (IWDG) removed the carcass to determine its cause of death, as the Mayo News reports.

Back on the North Coast, BelfastLive says a six-metre whale carcass surprised locals at Runkerry Strand near Portballintrae on 24 November.

The find came just weeks after a much larger fin whale carcass was found on Arranmore off the Donegal coast, as previously reported on Afloat.ie.

#MarineWildlife - The carcass of an 11-tonne sperm whale has washed up at Carnsore Point in Co Wexford, as the Gorey Guardian reports.

The 8.5m whale — discovered by local man Davie Rea on the rocky shore at the end of last week — was identified as an adult female by the Irish Whale and Dolphin Group (IWDG).

Kevin MacCormick of the IWDG added that the giant marine mammal appeared to be emaciated “so most likely it was not in good health”.

It’s been five years since the last sperm whale stranding on the Wexford coast, as the species is more often found in western waters.

#MarineWildlife - Not even two months in and 2017 is already the worst year on record for whale and dolphin strandings, according to the Irish Whale and Dolphin Group (IWDG).

As of Friday 17 February, a whopping 56 cetacean standings had been recorded — more than half of them identified as common dolphins.

Prior to 2010, the average numbers of standings were around 22, of which five would have been common dolphins, says the IWDG’s strandings officer Mick O’Connell.

The question of what is happening to cause such a spike in strandings throughout this decade prompted a meeting between the IWDG, Government agencies and representatives from Irish and European fishing fleets earlier this week.

“There is a disconnect somewhere,” says O’Connell, “as internationally accepted visual evidence of bycatch is seen in some strandings, and post-mortem reports on five common dolphins in Mayo in 2013 reported that their deaths were likely to be due to bycatch in a pelagic trawl net, yet Irish and EU observer schemes involving pelagic trawlers reported no bycatch in commercial pelagic hauls.”

The latest stranding was recorded in Fenit, Co Kerry on Wednesday (15 February) — a dolphin alleged by locals to have been caught in the nets of a large trawler offshore before being dumped overboard, as the Irish Mirror reports.

The Irish Examiner adds that another common dolphin with blood marks was found at Ballyconneely Beach in Connemara on the same day, while two days previous the emaciated carcass of a sperm whale was found on Nethertown Beach at the most south-easterly point of Co Wexford.

Last month, a spate of marine wildlife standings on the Waterford coast was blamed on pair trawling activity in the area.

I have been thinking of whales this week and remembering when I first saw a big one very close-up, so at the start of my podcast you can hear the sound, recorded underwater in the Atlantic Ocean of a humpback whale communicating with other whales.

The stranding of hundreds of whales on the New Zealand coastline was harrowing in the television pictures which showed the helplessness of these magnificent creatures when out of their environment, stranded ashore and the enormous efforts of human beings to refloat them. Some of those efforts were successful, but unfortunately, many whales died…..

The moment when I first saw a whale close-up is one of the memories etched on my mind. I was on the bow of Ireland’s first entry in the Round the World Yacht race in the Atlantic in May of 1990 when it happened. Suddenly, a huge whale was alongside us, so close I felt I could touch it. NCB Ireland was 85 feet long and the whale seemed, to my eyes, to be just as big and very close to the boat. I was awed by this magnificent creature which had emerged from the ocean and seemed to be staring at me. Having paced NCB for a while it effortlessly moved away, so much more part of the ocean world than us humans aboard NCB. I felt breathless as it disappeared from sight.

British Zoologist, Mark Carwardine, described such an experience well in his ‘Last Chance to See’ series on BBC Radio 4: “To have a huge whale approach your boat and look you straight in the eye is without doubt one of the most extraordinary experiences on the planet.”

That memory came to mind when Ireland’s top ocean racer, Damian Foxall, wrote to me in his present role as Recreation Education Manager at the Canadian Wildlife Federation. As the number of ocean yacht races increases, he is running a campaign to help scientists better understand areas of the world’s oceans where marine mammals are at risk of being struck by boats. Increasingly during these races there have been reports of yachts striking unidentified objects. “Currently the database for marine mammal strikes is very sparse,” he says. “We want to assemble reports of boats striking them. If everyone co-operates it will help plan future racing safely.”

#MarineScience - Scientists from Northern Ireland will lead a new project monitoring whale and dolphin sounds off the Scottish and Irish coasts, as BBC News reports.

The scheme led by the Agri-Food and Biosciences Institute (AFBI) will see a network of buoys deployed with devices to pick up cetacean chatter – as well as potentially harmful ocean sounds from sea traffic or industry.

"Displacement from noise is a very real effect and ... if it doesn't cause them to move will change their behaviours and, at the most acute levels, can cause physical and physiological damage to the animals,” says Dr Adam Mellor of the AFBI.

BBC News has more on the story HERE.

The Half Ton Class was created by the Offshore Racing Council for boats within the racing band not exceeding 22'-0". The ORC decided that the rule should "....permit the development of seaworthy offshore racing yachts...The Council will endeavour to protect the majority of the existing IOR fleet from rapid obsolescence caused by ....developments which produce increased performance without corresponding changes in ratings..."

When first introduced the IOR rule was perfectly adequate for rating boats in existence at that time. However yacht designers naturally examined the rule to seize upon any advantage they could find, the most noticeable of which has been a reduction in displacement and a return to fractional rigs.

After 1993, when the IOR Mk.III rule reached it termination due to lack of people building new boats, the rule was replaced by the CHS (Channel) Handicap system which in turn developed into the IRC system now used.

The IRC handicap system operates by a secret formula which tries to develop boats which are 'Cruising type' of relatively heavy boats with good internal accommodation. It tends to penalise boats with excessive stability or excessive sail area.

Competitions

The most significant events for the Half Ton Class has been the annual Half Ton Cup which was sailed under the IOR rules until 1993. More recently this has been replaced with the Half Ton Classics Cup. The venue of the event moved from continent to continent with over-representation on French or British ports. In later years the event is held biennially. Initially, it was proposed to hold events in Ireland, Britain and France by rotation. However, it was the Belgians who took the ball and ran with it. The Class is now managed from Belgium.
