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 Times has more on the story HERE.

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.

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.

About the Golden Globe Race

The Golden Globe Race is the original round the world yacht race. In 1968, while man was preparing to take his first steps on the moon, a mild mannered and modest young man was setting out on his own record breaking voyage of discovery. Off shore yacht racing changed forever with adventurers and sailors, inspired by Sir Robin Knox-Johnston, following in his pioneering wake. Nine men started the first solo non-stop sailing race around the World. Only one finished. History was made. Navigating with a sextant, paper charts and an accurate and reliable time piece, Sir Robin navigated around the world. In 2018, to celebrate 50 years since that first record breaking achievement, the Golden Globe Race was resurrected. It instantly caught the attention of the worlds media as well as adventures, captivated by the spirit and opportunity. The original race is back.

The Golden Globe Race: Stepping back to the golden age of solo sailing

Like the original Sunday Times event back in 1968/9, the 2018 Golden Globe Race was very simple. Depart Les Sables d'Olonne, France on July 1st 2018 and sail solo, non-stop around the world, via the five Great Capes and return to Les Sables d'Olonne. Entrants are limited to use the same type of yachts and equipment that were available to Robin Knox-Johnston in that first race. That means sailing without modern technology or benefit of satellite-based navigation aids.

Competitors must sail in production boats between 32ft and 36ft overall (9.75 10.97m) designed prior to 1988 and having a full-length keel with rudder attached to their trailing edge. These yachts will be heavily built, strong and steady, similar in concept to Robin's 32ft vessel Suhaili.

In contrast to the current professional world of elite ocean racing, this edition travels back to a time known as the 'Golden Age' of solo sailing. Suhaili was a slow and steady 32ft double-ended ketch based on a William Atkins ERIC design. She is heavily built of teak and carried no computers, GPS, satellite phone nor water-maker, and Robin completed the challenge without the aid of modern-day shore-based weather routing advice. He had only a wind-up chronometer and a barograph to face the world alone, and caught rainwater to survive, but was at one with the ocean, able to contemplate and absorb all that this epic voyage had to offer.

This anniversary edition of the Golden Globe Race is a celebration of the original event, the winner, his boat and that significant world-first achievement. Competitors in this race will be sailing simple boats using basic equipment to guarantee a satisfying and personal experience. The challenge is pure and very raw, placing the adventure ahead of winning at all costs. It is for 'those who dare', just as it was for Knox-Johnston.

They will be navigating with sextant on paper charts, without electronic instruments or autopilots. They will hand-write their logs and determine the weather for themselves.

Only occasionally will they talk to loved ones and the outside world when long-range high frequency and ham radios allow.

It is now possible to race a monohull solo around the world in under 80 days, but sailors entered in this race will spend around 300 days at sea, challenging themselves and each other. The 2018 Golden Globe Race was a fitting tribute to the first edition and it's winner, Sir Robin Knox-Johnston.

Background on Don McIntyre (61) Race Founder

Don is an inveterate sailor and recognised as one of Australia s greatest explorers. Passionate about all forms of adventure and inspiring others, his desire is to recreate the Golden Age of solo sailing. Don finished 2nd in class in the 1990-91 BOC Challenge solo around the world yacht race.
