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.

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.

The oldest ever sailor was Syd Fischer (88 years, 2015).

As a baby, Raud O'Brien did his first of some six Sydney Hobarts on his parent's Wraith of Odin (sic). As a veteran at three, Raud broke his arm when he fell off the companionway steps whilst feeding biscuits to the crew on watch Sophie Tasker sailed the 1978 race as a four-year-old on her father’s yacht Siska, which was not an official starter due to not meeting requirements of the CYCA. Sophie raced to Hobart in 1979, 1982 and 1983.

Quite a number of teenage boys and girls have sailed with their fathers and mothers, including Tasmanian Ken Gourlay’s 14-year-old son who sailed on Kismet in 1957. A 12-year-old boy, Travis Foley, sailed in the fatal 1998 race aboard Aspect Computing, which won PHS overall.

In 1978, the Brooker family sailed aboard their yacht Touchwood – parents Doug and Val and their children, Peter (13), Jacqueline (10), Kathryne (8) and Donald (6). Since 1999, the CYCA has set an age limit of 18 for competitors

Jane (‘Jenny’) Tate, from Hobart, sailed with her husband Horrie aboard Active in the 1946 Race, as did Dagmar O’Brien with her husband, Dr Brian (‘Mick’) O’Brien aboard Connella. Unfortunately, Connella was forced to retire in Bass Strait, but Active made it to the finish. The Jane Tate Memorial Trophy is presented each year to the first female skipper to finish the race

In 2019, Bill Barry-Cotter brought Katwinchar, built in 1904, back to the start line. She had competed with a previous owner in 1951. It is believed she is the oldest yacht to compete. According to CYCA life member and historian Alan Campbell, more than 31 yachts built before 1938 have competed in the race, including line honours winners Morna/Kurrewa IV (the same boat, renamed) and Astor, which were built in the 1920s.

Bruce Farr/Farr Yacht Design (NZL/USA) – can claim 20 overall wins from 1976 (with Piccolo) up to and including 2015 (with Balance)

Screw Loose (1979) – LOA 9.2m (30ft); Zeus II (1981) LOA 9.2m

TKlinger, NSW (1978) – LOA 8.23m (27ft)

Wild Oats XI (2012) – LOA 30.48m (100ft). Wild Oats XI had previously held the record in 2005 when she was 30m (98ft)
