Aerial Survey of Whales Begins

The first ever Air Corps survey of whale and dolphin activity in Irish waters is set to begin today, the Irish Times reports.
A survey team accompanied by members of the Irish Whale and Dolphin Group (IWDG) were scheduled to take off from Casement Aerodrome this morning headed for the southeast coast, where humpback whales have recently been sighted near Curracloe and Hook Head.
According to the IWDG, 19 whale and dolphin species have been recorded in Irish waters since 1948, the most common sightings being harbour porpoises.

The Irish Whale and Dolphin Group's (IWDG) recent workshop on the post-mortem examination of stranded dolphins and whales is hoped to encourage the building of much needed experience for Ireland's vets.
More than 20 veterinarians from across the country attended the workshop in Athlone, where they were shown how to carry out a post-mortem from a research perspective and taken through the post-mortem protocol, as well as the collection of samples for various parameters from bacteriology to genetics.
"The IWDG have long advocated that the post-mortem examination of stranded cetaceans should be carried out by veterinary pathologists to determine their cause of death and provide samples for life-history studies," said the group's Dr Simon Berrow.

A new pontoon intended to refloat beached whales and dolphins along the Atlantic seaboard was demonstrated at the weekend ahead of the Galway Science & Technology Festival.
The Irish Times reports that divers, scientists and local volunteers were among those participating in the training exercise on Gurteen beach, near Roundstone, which involved rescuing and refloating a dummy pilot whale.
Dr Simon Berrow of the Irish Whale and Dolphin Group (IWDG) which ran the exercise said he hoped other coastal communities would follow the example with their own training sessions, given the growing number of strandings along Ireland's west coast.
The new pontoon - which was put on display in the festival exhibition at NUI Galway on Sunday - was purchased with funds raised by the local community and a BBC television team producing the latest series by popular adventurer Monty Halls.

Renowned diver Monty Halls is set to present a public talk on his marine animal work filming whales, sharks and dolphins around the world tomorrow night (7 October).

Halls, who has been in Ireland since April making his latest documentary series for the BBC, has been assisting the Irish Whale and Dolphin group (IWDG) with its research on whales, dolphins and basking sharks in Irish waters.

The diver, filmmaker and former Royal Marine, who is also a popular motivational speaker and performance coach, will talk on his experiences filming and diving with marine mammals around the world, and will surely provide some great entertainment.

The talk, part of the Tales of the Whales Lecture Series organised by the IWDG and the Galway-Mayo Institute of Technology (GMIT), begins at 8pm on Thursday 7 October in Lecture Room 1000 at GMIT, Dublin Road, Galway. The event is free and all are welcome to attend.

Pictures of Dolphins jumping off Roches Point in Cork harbour have been captured for youtube viewers courtesy of a Cork fishing trip this week. The three harbour dolphins jump clean out of the water in the clip below from about 2:20 on the timeline.  A Lovely marine animal sight on a summers evening!

Atlantic Dolphins choose to eat high-energy fish to suit their energetic lifestyles, scientists have found.
A study of dolphins off the French coast shows that dolphins shy away from less calorie-dense prey in favour of high-energy food. This dispels a myth that dophins are opportunistic feeders that take any food that comes their way.
The study was carried out by Dr Jerome Spitz and other scientist at the University of La Rochelle in France, who looked at the eating habits of short-beaked common dolphins ( Delphinus delphis ).
This species are the most common type of dolphin in nearby Atlantic waters. The team studied the stomach contents of dolphins caught accidentally in tuna drift nets to see what they ate. They then compared what they found in the dolphins' stomachs with what surveys of trawling fish catches indicated as plentiful in the same waters.
What they found was that dolphins actively select their prey based on its energy density, preferring deep-sea species like lanternfish instead of fish that have lower energy densities.
The dolphins studied turned their noses up at fish with under 5kJ of energy per gram, and sought out rarer breeds of fish that had a higher energy rate.
Two favourites were less common species of  lantern fish, the Kroyer's lanternfish  and the Glacier lanternfish  which have 7.9kJ and 5.9kJ per gram respectively.

Royal National Lifeboat Institute (RNLI) in Ireland Information

The Royal National Lifeboat Institution (RNLI) is a charity to save lives at sea in the waters of UK and Ireland. Funded principally by legacies and donations, the RNLI operates a fleet of lifeboats, crewed by volunteers, based at a range of coastal and inland waters stations. Working closely with UK and Ireland Coastguards, RNLI crews are available to launch at short notice to assist people and vessels in difficulties.

RNLI was founded in 1824 and is based in Poole, Dorset. The organisation raised €210m in funds in 2019, spending €200m on lifesaving activities and water safety education. RNLI also provides a beach lifeguard service in the UK and has recently developed an International drowning prevention strategy, partnering with other organisations and governments to make drowning prevention a global priority.

Irish Lifeboat Stations

There are 46 lifeboat stations on the island of Ireland, with an operational base in Swords, Co Dublin. Irish RNLI crews are tasked through a paging system instigated by the Irish Coast Guard which can task a range of rescue resources depending on the nature of the emergency.

Famous Irish Lifeboat Rescues

Irish Lifeboats have participated in many rescues, perhaps the most famous of which was the rescue of the crew of the Daunt Rock lightship off Cork Harbour by the Ballycotton lifeboat in 1936. Spending almost 50 hours at sea, the lifeboat stood by the drifting lightship until the proximity to the Daunt Rock forced the coxswain to get alongside and successfully rescue the lightship's crew.

32 Irish lifeboat crew have been lost in rescue missions, including the 15 crew of the Kingstown (now Dun Laoghaire) lifeboat which capsized while attempting to rescue the crew of the SS Palme on Christmas Eve 1895.

FAQs

While the number of callouts to lifeboat stations varies from year to year, Howth Lifeboat station has aggregated more 'shouts' in recent years than other stations, averaging just over 60 a year.

Stations with an offshore lifeboat have a full-time mechanic, while some have a full-time coxswain. However, most lifeboat crews are volunteers.

In 2019, 8,941 lifeboat launches saved 342 lives across the RNLI fleet.

The Irish fleet is a mixture of inshore and all-weather (offshore) craft. The offshore lifeboats, which range from 17m to 12m in length are either moored afloat, launched down a slipway or are towed into the sea on a trailer and launched. The inshore boats are either rigid or non-rigid inflatables.

The Irish Coast Guard in the Republic of Ireland or the UK Coastguard in Northern Ireland task lifeboats when an emergency call is received, through any of the recognised systems. These include 999/112 phone calls, Mayday/PanPan calls on VHF, a signal from an emergency position indicating radio beacon (EPIRB) or distress signals.

The Irish Coast Guard is the government agency responsible for the response to, and co-ordination of, maritime accidents which require search and rescue operations. To carry out their task the Coast Guard calls on their own resources – Coast Guard units manned by volunteers and contracted helicopters, as well as "declared resources" - RNLI lifeboats and crews. While lifeboats conduct the operation, the coordination is provided by the Coast Guard.

A lifeboat coxswain (pronounced cox'n) is the skipper or master of the lifeboat.

RNLI Lifeboat crews are required to follow a particular development plan that covers a pre-agreed range of skills necessary to complete particular tasks. These skills and tasks form part of the competence-based training that is delivered both locally and at the RNLI's Lifeboat College in Poole, Dorset

 

While the RNLI is dependent on donations and legacies for funding, they also need volunteer crew and fund-raisers.
