Citizen scientists from Westport Aquarium in Washington state, USA, and Galway Atlantaquaria have collaborated on a project to raise awareness about microplastics.

Named “SeaLegs”, the project involved monitoring local water sources for microplastic litter.

From early summer, this year, the trawl teams from Ireland and America were tasked to select a local water source and check for microplastics.

The SeaLegs devices were made from recycled and upcycled materials, and the trawls took place in areas including the Humptulips River and Grays Harbour in Washington state and Galway Bay.

"Kayakers and fishermen and many other water enthusiasts wondered why we were pulling a pair of baby leggings through the local waterways"

Garry Kendellen, of Galway Atlantaquaria said, “I loved meeting people during the trawls, the tights in the water were a great conversation starter, and I was able to talk about Clean Coasts volunteering and the problems of microplastics”.

“The aquarium has been involved in many projects like this, but this one was really special and thought-provoking,” he said.

Six trials were conducted by the teams. It was agreed that even if the trawls were unsuccessful in their goal of capturing litter and microplastics, they would still be a conversation starter about litter, marine litter, water rights, social behaviour, litter collection/disposal, biodiversity, and citizen science.

Katherine Myrsell, director of Westport Aquarium, said: “Kayakers and fishermen and many other water enthusiasts wondered why we were pulling a pair of baby leggings through the local waterways.” 

“After deploying the SeaLegs, there was a lot of work to sort and sieve the samples.

After a day of collecting samples, we had to sift through the mass of organic matter and find microplastics,” she said.

“This was no easy feat as microplastics are fragments of any type of plastic less than 5 mm (0.20 in) in length. The trawl teams had very limited quality microscopes, so it was a painstaking process to sort the samples,” she said.

“After much scanning and sifting, we were able to identify microplastics in almost every trawl. The fibres we discovered could not be confused with anything organic as they were blue, white, and red in colour,” she said.

The findings are in the SeaLegs Project Report

New Zealand based Sealegs International has announce the coming release of the Terminator 755 Amphibious by Sealegs at the Auckland On Water Boat Show. The craft features System 60, the amphibious enablement system (AES) by Sealegs, and was developed by Terminator Boats.

This latest addition to the expanding amphibious product range demonstrates the on-going efforts and success of the Sealegs AES Strategy previously seen in craft released by Stabicraft and ASIS. Sealegs plans to continue the strategy of developing amphibious craft through offering amphibious systems to global boat manufacturers to widen our product range and reach of customers.

Brazen Composites and its subsidiary Terminator Boats have a long history in building composite craft. The Terminator 755 is the first 100% fiberglass model released with Sealegs that does not feature the Hypalon or Aluminium pontoons previously seen in the rest of the Sealegs range.

Sealegs CEO, David McKee Wright said “with every new partner we appoint under the AES strategy, our systems and processes improve to better accommodate the needs of a wider range of boat manufactures. The Terminator 755 demonstrates the ability to leverage the expertise of alternative boat manufacturers, as we benefitted from the skills of our partner, Brazen Composites, to release the all-fiberglass boat. A skillset where Sealegs has limited experience.”

He went on to say “by leveraging the efficient manufacturing base in Malaysia, and the lower cost manufacturing process of fiberglass, we have been able to introduce an introductory price that is better than any other in the Sealegs range.”

The Terminator 755 Amphibious by Sealegs will be available for viewing at the Auckland On Water Boat Show from the 29 September through 2 October 2016, on Sealegs Island, Viaduct Events Centre, Auckland. The standard hull and Amphibious Enablement System will have a retail starting price of just $149,000 + outboard, options and gst. Sealegs will also be running an introductory special until the end of the boat show for just $125,000+gst.

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.

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
