Tagged Basking Shark re-sighted between Ireland and Scotland

Published

on

A Basking Shark tagged off County Clare on the western seaboard of Ireland this year was recently re-sighted off the west coast of Scotland. The shark was tagged on 25 April 2020 with a numbered red coloured tag off Kilkee and was re-sighted nearly 600km further north on 19 August 2020 near Hyskier Lighthouse in the Sea of the Hebrides. This re-sighting record, 116 days after the tag was deployed confirms the connectivity between Irish and Scottish waters.

Dr Simon Berrow of the Irish Basking Shark Group who tagged the shark off west Clare in April said “we have long been aware that sharks in Irish waters are moving north through the early summer along the west coast and into Scottish waters, but this is the longest duration between re-sightings of our simple shark tags, which is fantastic and encouraging”.

The tagged shark was observed by snorkelling with Basking Shark Scotland. Founder Shane Wasik said “This is the third Irish tag we have recorded in recent years and it gives us a great sense of purpose to contribute to this Irish conservation led research project. The passenger were very excited to discover the tag and were so pleased to hear about the match from IBSG group. We welcome future scientific collaboration to assist in the understanding of this species and work towards protection over their entire Atlantic migration”.

The Irish Basking Shark Group have tagged over 500 individual sharks since 2008 and it’s not unexpected that we are getting regular records from movements between Donegal and Scotland, but to get a re-sighting after from Co Clare after such a long period and distance demonstrates that other areas of Ireland also share this shark population,” said Dr Emmett Johnston, who works closely with Dr Berrow on the long-running Irish shark tagging project.

Basking sharks first appear in inshore Irish waters in the early spring between April and May, but generally appear later off the west coast of Scotland. This is thought to be linked to the later zooplankton bloom further north off Scotland, which are the sharks main prey.

This research is important to demonstrate that these sharks cross international boundaries and any management needs to consider their whole range. Basking sharks are protected under a suite of legislation in the UK including Scotland and Northern Ireland. The Sea of the Hebrides is also proposed as a Marine Protected Area for basking sharks by the Scottish government. No such measures exist for Ireland but Dr Berrow commented positively that “major collaborations are now underway in Irish waters that will provide vital information on how best to conserve these magnificent sharks while they are in our care”.

Diving below the waves of the Western Cape, South Africa – Long Beach at night (Watch Video)

Published

on

Head under the waves of False Bay and explore the incredible diversity that is found along the Western Cape. The bay has popular dive spots from diving amongst the biodiverse underwater kelp forests to jumping in with the playful and friendly cape fur sealions (Arctocephalus pusillus). The bay along with the rest of the South Africa coast is known for the range of shark species that are found from the shallow coastal shores out into the open oceans. The coast is also home to numerous endemic shark species such as puffadder shyshark (Haploblepharus edwardsii) and Pyjama shark.

Longbeach is a shallow shore dive close to the coastal town of Simonstown on the Western Cape. The dive is mainly made up of diving across the sand with a few wreckages, rocks and outcrops where there’s algae growing. A pipeline can be found at the site which provides locations for species such as Pyjama Sharks (Poroderma africanum) and octopus (Octopus vulgaris) to shelter. Diving at night at the site provides the opportunity to see species that are more often hidden during the day such as cape Squid (Loligo reynaudii) and Biscuit Skate (Raja straeleni). Other shark species such as the small Puff Adder Shyshark (Haploblepharus edwardsii) are also occasionally seen at the site.

Book Review – The Final Dive: The Life and Death of ‘Buster’ Crabbe (2007)

Published

on

It was the height of the Cold War. The Soviet Cruiser Ordzhonikidz, supported by two destroyers, had brought Soviet leaders Khruschev and Bulganin to Britain for sensitive meetings with the British Government. The ships were moored in Portsmouth harbour and the Prime Minister, Sir Anthony Eden, had expressly forbidden any clandestine inspection of them. However, on the morning of 19th April 1956 Commander Lionel ‘Buster’ Crabbe, an experienced naval diver, slipped into the cold waters of Portsmouth harbour. His top secret mission was to photograph the hull, propellers and rudder of the Ordzhonikidze. He was never seen alive again.

A badly decomposed body, with head and hands missing, was discovered by fishermen in Chichester harbour months later. It was claimed to be the missing body of Buster Crabbe – but many had doubts. The incident marked the start of a controversy that claimed the posts of several high ranking naval, government and intelligence service personnel. The author of The Final Dive, Don Hale, claims it is one that still rages and which may not be resolved even when secret government files are released in 2057.

Don Hale, an acknowledged campaigning journalist and former Journalist of the Year brings all his experience and skill to unravelling this longstanding scandal. He has drawn upon official reports and private letters, statements from government representatives, fellow officers and friends to piece together Buster’s life and events leading to his disappearance and subsequent investigation. He speaks of “inquiries blocked by intrigue, constant cover-ups and government bureaucracy coupled with threats relating to the Official Secrets Act” (p. xi). If you like reading about subterfuge on a grand scale you will enjoy The Final Dive.

Don Hale’s meticulous account of the life of Buster Crabbe is supported by dozens of black and white photos and extracts from numerous official documents. It reveals how an amazing series of civilian jobs, wartime activities and friendships with high ranking government officials, British intelligence officers, American CIA operatives. . . and now known spies, prepared him for his final dive and perhaps his fate. One of Crabbe’s acquaintances was the author Ian Fleming – of James Bond fame. Indeed, it is suggested that Fleming based the character of 007 on Buster Crabbe. After reading of his exploits, both before WWII, his bomb disposal work during the war, and afterwards it is easy to see why. Certainly, those who worked with Buster Crabbe “all agree he was fearless.” (p.59). After reading of his exploits one wonders if he was too fearless.

In the later stage of Buster’s life, prior to his disappearance, Don Hall recounts “a constant merry-go-round of overseas assignments” (p. 118) for Crabbe and how he “began to receive increasingly hazardous commissions” (p. 136). It culminated in the morning dive in Portsmouth harbour. Hale’s forsensic-like account of the events surrounding the final dive and aftermath reveals absolute panic and bungling behind the scenes as official answers conflict with known facts. He describes how “The whole incident still seems bathed in secrecy, with the true facts deliberately buried in bureaucracy, and supported at the highest level by an incredible cover-up operation”.(p. 205).

A final comment by Don Hale adds to the intrigue. He states “The only part of the Crabbe puzzle about which I am not certain is not who sent him – we know the answer to that – but why on earth he was he sent, possibly at considerable risk?” (p. 248). After reading The Final Dive: The Life and Death of ‘Buster’ Crabbe you will no doubt have your own ideas.
