#Rio2016 - Sailors in Rio who ingest just three teaspoons of water from the Olympic courses on Guanabara Bay have a 99% chance of being infected by a virus.

That's according to the latest damning findings from the Associated Press, following from its own investigation earlier this year that found levels of viruses detected at the Olympic sailing venue to be as much as 1.7 million times this allowed on California beaches.

Samples taken more recently now indicate that a high concentration of viruses is detectable even more than a kilometre offshore away from the pollution sources that have plagued Rio's waters for decades.

Despite assurances by the ISAF – which previously floated the idea of moving the sailing venue out of Rio to cleaner waters – that steps were being taken "to ensure the health and safety of all athletes", there was still an illness rate of 7% among sailors competing at an Olympic test event in August.

That figure included 49er bronze medallist Erik Heil, who was treated for severe inflammations in his legs and a hip.

The cause of his illness turned out to be the superbug MRSA, and Heil has since proposed wearing plastic overalls while sailing out from the shore to limit his exposure to that an other bacterial infections.

But experts in waterborne viruses have told the AP that such efforts are futile when Rio's Olympic waterways "are as rife with pathogens far offshore as they are nearer land".

The AP has much more on the story HERE, coming in the same week as the ISAF's chief executive Peter Sowrey resigned after only six months in the job – the latest in a spate of high-profile departures from sailing's world governing body.

#ebola – The Department of Transport, Tourism and Sport has been requested to publicise the attached (downloadable below as a word file) Health Service Executive letter regarding the submission of a Maritime Declaration of Health for ships docking at Irish ports, which have called at an Ebola EVD affected area or have crew/passengers that joined the vessel from such an area, or are suspected of having been in contact with the Ebola virus or an affected person within the past.

#Fishing - "Absolutely hammered" is how a Carlingford Lough oyster farmer describes the state of his business after £350,000 (€404,000) worth of his stock was destroyed by a virus in the recent heatwave.

And as the Belfast Telegraph reports, Darren Cunningham now fears financial ruin after at least 80% of his juvenile oysters were wiped out by the ostreid herpes virus, which kills the shellfish when the water temperature rises above 16 degrees.

Unfortunately for Cunningham and fellow oysterman Harold Henning, who fears a total loss of his young oysters, Stormont has no compensation scheme in place for lost stocks in Northern Ireland.

The Belfast Telegraph has more on the story HERE.

Marine Institute Research Vessel Tom Crean

Ireland’s new marine research vessel will be named the RV Tom Crean after the renowned County Kerry seaman and explorer who undertook three major groundbreaking expeditions to the Antarctic in the early years of the 20th Century which sought to increase scientific knowledge and to explore unreached areas of the world, at that time.

Ireland's new multi-purpose marine research vessel RV Tom Crean, was delivered in July 2022 and will be used by the Marine Institute and other State agencies and universities to undertake fisheries research, oceanographic and environmental research, seabed mapping surveys; as well as maintaining and deploying weather buoys, observational infrastructure and Remotely Operated Vehicles.

The RV Tom Crean will also enable the Marine Institute to continue to lead and support high-quality scientific surveys that contribute to Ireland's position as a leader in marine science. The research vessel is a modern, multipurpose, silent vessel (designed to meet the stringent criteria of the ICES 209 noise standard for fisheries research), capable of operating in the Irish Exclusive Economic Zone (EEZ). The Tom Crean is able to go to sea for at least 21 days at a time and is designed to operate in harsh sea conditions.

Irish Marine Research activities

The new state-of-the-art multi-purpose marine research vessel will carry out a wide range of marine research activities, including vital fisheries, climate change-related research, seabed mapping and oceanography.

The new 52.8-metre modern research vessel, which will replace the 31-metre RV Celtic Voyager, has been commissioned with funding provided by the Department of Agriculture, Food and the Marine approved by the Government of Ireland.

According to Aodhán FitzGerald, Research Vessel Manager of the MI, the RV Tom Crean will feature an articulated boom crane aft (6t@ 10m, 3T@ 15m), located on the aft-gantry. This will be largely used for loading science equipment and net and equipment handling offshore.

Mounted at the stern is a 10T A-frame aft which can articulate through 170 degrees which are for deploying and recovering large science equipment such as a remotely operated vehicle (ROV’s), towed sleds and for fishing operations.

In addition the fitting of an 8 Ton starboard side T Frame for deploying grabs and corers to 4000m which is the same depth applicable to when the vessel is heaving but is compensated by a CTD system consisting of a winch and frame during such operations.

The vessel will have the regulation MOB boat on a dedicated davit and the facility to carry a 6.5m Rigid Inflatable tender on the port side.

Also at the aft deck is where the 'Holland 1' Work class ROV and the University of Limericks 'Etain' sub-Atlantic ROV will be positioned. In addition up to 3 x 20’ (TEU) containers can be carried.

The newbuild has been engineered to endure increasing harsher conditions and the punishing weather systems encountered in the North-East Atlantic where deployments of RV Tom Crean on surveys spent up to 21 days duration.

In addition, RV Tom Crean will be able to operate in an ultra silent-mode, which is crucial to meet the stringent criteria of the ICES 209 noise standard for fisheries research purposes.

The classification of the newbuild as been appointed to Lloyds and below is a list of the main capabilities and duties to be tasked by RV Tom Crean:

  • Oceanographic surveys, incl. CTD water sampling
  • Fishery research operations
  • Acoustic research operations
  • Environmental research and sampling operation incl. coring
  • ROV and AUV/ASV Surveys
  • Buoy/Mooring operations
