#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.

#DolphinDeaths - Hundreds of bottlenose dolphins have died in strandings along the east coast of the United States this summer - and a measles-like virus could be to blame.

As The Irish Times reports, the National Oceanic and Atmospheric Administration (NOAA) is currently investigating the extraordinary die-off, which has been tentatively connected to morbillivirus, an immune system suppressor similar to the virus that causes human measles.

In numbers not seen since the late 1980s, as many as 333 dolphin carcasses have been found on the shoreline between New York and North Carolina, more than 10 times the average for this time of year.

Researchers from universities and marine institutes are concentrating on the Virginia coastline, where the majority of the dead cetaceans have been found, and believe they have identified evidence of morbillivirus in nearly all sampled carcasses.

Wired Science says scientists do not yet know what caused the outbreak, though they speculate that dolphins may simply have lost their natural immunity to the virus since the last attack.

And according to the NOAA's Teri Rowles: “At this point, there isn’t anything to stop the virus.”

As of yet there are no indications if the virus could migrate to dolphin populations on this side of the Atlantic, particularly in the designated cetacean sanctuary of Irish waters.

#Fishing - The Marine Institute is encouraging the agreement of a new code of practice for oyster fishing at Ballinakill Bay in Co Galway, which is set to lose its disease-free status.

Galway Bay FM reports that a single oyster out of 900 tested at the bay, near Letterfrack on the north-west coast of Connemara, tested positive for the Ostreid herpes virus two years ago as part of an EU-supported programme.

Though accounting for just 0.11% of the entire sample, the positive test is enough to strip the area of its clean status.

Senator Trevor O'Clochartaigh raised the issue in the Seanad last week, which prompted the Department of the Marine to confirm that the Marine Institute recommends a code of practice that would see the area's status eventually reinstated.

#MARINE WILDLIFE - Some 46 reports of stranded whales and dolphins in Northern Ireland are among the thousands recorded across the UK over the last six years, according to BBC News.

A new study co-ordinated by the Zoological Socoety of London (ZSL) shows that some 3,500 cetaceans were stranded on the British coastline between 2005 and 2010.

Though year-on-year figures have fallen overall, is presumed that many more strandings have gone undetected.

Many were found to have died of disease or starvation – particular harbour dolphins.

But human activity such as fishing, shipping and chemical pollution also poses a significant threat to marine wildlife in the waters around the British Isles, said Rob Deaville of the ZSL.

The public is being encouraged to report stranded marine mammals to help create a more accurate picture.

Experts in the United States are investigating the possibility of a disease outbeak as the number of dead seals found on New England beaches continues to grow.
The Gloucester Times in Massachusetts reports that some 128 harbour seals have been found deceased this year along the coastline from Massachusetts to Maine.
Initial results from post-mortems carried out on 10 harbour seals washed up in northern Massachusetts indicate no direct human involvement, and also ruled out physical attacks or effects of fishing.
All the dead seals are reportedly young and healthy, with enough body fat to rule out starvation.
"We have collected biological samples and are looking at potential biological toxins," said a spokesperson for the National Oceanic and Atmospheric Administration. "At this point we aren't ruling anything out."
It's believed that the marine wildlife casualties are unrelated to the recent discovery of seven dead seals in Donegal, due to the distance between the incidents and the difference in species.

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.

RV Tom Crean Specification Overview

  • Length Overall: 52.8 m
  • Beam 14m
  • Draft 5.2M 

Power

  • Main Propulsion Motor 2000 kw
  • Bow Thruster 780 kw
  • Tunnel thruster 400 kw

Other

  • Endurance  21 Days
  • Range of 8,000 nautical miles
  • DP1 Dynamic Positioning
  • Capacity for 3 x 20ft Containers

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
