Marine scientists from University College Cork have discovered plastic at the bottom of a deep submarine canyon while investigating cold-water coral habitats.

UCC’s Marine Geology Research Group has been investigating cold-water coral habitats in the Porcupine Bank Canyon, some 320km due west of Dingle, on a research expedition led by UCC’s Dr Aaron Lim on board the Marine Institute’s RV Celtic Explorer.

The team had recovered eight novel monitoring stations, called ‘landers’, worth €450,000 and deployed between 700m and 2500m water depth by the Marine Institute’s Remotely Operated Vehicle (ROV) Holland 1 earlier this summer.

The monitoring stations record the speed, temperatures and direction of the currents around these habitats as well as trapping samples of the food, sediments and microplastic being deposited around the corals, to understand conditions and how the corals are coping with changing oceans.

The researchers found plastic in the bottom of one canyon at 2,125m water depth — as deep as ten Eiffel Towers stacked on top of one another.

The reach of human plastic waste is now confirmed as this deep, even 320km offshore.

“It’s always sad to see plastic rubbish in these otherwise pristine habitats. It’s quite incredible that our plastic waste can get this far out and so deep in the oceans,” said Professor Andy Wheeler of UCC, who has pioneered research on cold-water coral mounds offshore of Ireland over the past 20 years.

“I don’t think people think about this when that dump their rubbish. We’re also trying to see if microplastics are being fed to the corals from above. We’ve just got the samples; let’s hope we're wrong.”

The Porcupine Bank Canyon is teeming with a whole range of cold-water coral habitats, just on Ireland’s doorstep, says Dr Lim.

“The environment is much more dynamic than we thought, with two of the monitoring stations knocked over by the currents; food supply for the coral is variable but the corals are doing okay.

“Some of these habitats have existed for millions of years and have grown so large they resemble hills made of coral, called coral mounds.

“This is the first time eight of these monitoring stations have been deployed and collected using the ROV Holland 1. It will provide scientists with an insight into the processes affecting these cold-water coral habitats, food sources and the impact of microplastics.”

Dr Lim said Ireland’s cold-water coral reefs are found in the cold, dark ocean at water depths of 600m to 1,000m along our continental margin.

“Not only is this expedition vital for understanding these habitats and our impact upon them, it also acts as a baseline to start monitoring how our deep-water habitats here are changing,” he added.

The team has a research agenda which will see them return to the canyon and other habitats alike for a number of years, to monitor the changes in the environment around these habitats. The monitoring stations will be brought back to UCC for detailed analyses.

This research survey is carried out with the support of the Marine Institute, funded under the Marine Research Programme 2014-2020 by the Government to support and promote the Atlantic Ocean Research Alliance, which facilitates common research and knowledge exchange for us to provide healthy, resilient oceans for our future generations.

The survey has also received funding from Science Foundation Ireland, Geological Survey Ireland and UCC.

RORC Fastnet Race

This race is both a blue riband international yachting fixture and a biennial offshore pilgrimage that attracts crews from all walks of life:- from aspiring sailors to professional crews; all ages and all professions. Some are racing for charity, others for a personal challenge.

For the world's top professional sailors, it is a 'must-do' race. For some, it will be their first-ever race, and for others, something they have competed in for over 50 years! The race attracts the most diverse fleet of yachts, from beautiful classic yachts to some of the fastest racing machines on the planet – and everything in between.

The testing course passes eight famous landmarks along the route: The Needles, Portland Bill, Start Point, the Lizard, Land’s End, the Fastnet Rock, Bishop’s Rock off the Scillies and Plymouth breakwater (now Cherbourg for 2021 and 2023). After the start in Cowes, the fleet heads westward down The Solent, before exiting into the English Channel at Hurst Castle. The finish for 2021 is in Cherbourg via the Fastnet Rock, off the southern tip of Ireland.

  • The leg across the Celtic Sea to (and from) the Fastnet Rock is known to be unpredictable and challenging. The competitors are exposed to fast-moving Atlantic weather systems and the fleet often encounter tough conditions
  • Flawless decision-making, determination and total commitment are the essential requirements. Crews have to manage and anticipate the changing tidal and meteorological conditions imposed by the complex course
  • The symbol of the race is the Fastnet Rock, located off the southern coast of Ireland. Also known as the Teardrop of Ireland, the Rock marks an evocative turning point in the challenging race
  • Once sailors reach the Fastnet Rock, they are well over halfway to the finish in Cherbourg.

Fastnet Race - FAQs

The 49th edition of the biennial Rolex Fastnet Race will start from the Royal Yacht Squadron line in Cowes, UK on Sunday 8th August 2021.

The next two editions of the race in 2021 and 2023 will finish in Cherbourg-en-Cotentin at the head of the Normandy peninsula, France

Over 300. A record fleet is once again anticipated for the world's largest offshore yacht race.

The international fleet attracts both enthusiastic amateur, the seasoned offshore racer, as well as out-and-out professionals from all corners of the world.

Boats of all shapes, sizes and age take part in this historic race, from 9m-34m (30-110ft) – and everything in between.

The Fastnet Race multihull course record is: 1 day 4 hours 2 minutes and 26 seconds (2019, Ultim Maxi Edmond de Rothschild, Franck Cammas / Charles Caudrelier)

The Fastnet Race monohull course record is: 1 day, 18 hours, 39 minutes (2011, Volvo 70, Abu Dhabi Ocean Racing).

David and Peter Askew's American VO70 Wizard won the 2019 Rolex Fastnet Race, claiming the Fastnet Challenge Cup for 1st in IRC Overall.

Rolex SA has been a longstanding sponsor of the race since 2001.

The first race was in 1925 with 7 boats. The Royal Ocean Racing Club was set up as a result.

The winner of the first Fastnet Race was the former pilot cutter Jolie Brise, a boat that is still sailing today.

Cork sailor Henry P F Donegan (1870-1940), who gave his total support for the Fastnet Race from its inception in 1925 and competed in the inaugural race in his 43ft cutter Gull from Cork.

Ireland has won the Fastnet Race twice. In 1987 the Dubois 40 Irish Independent won the Fastnet Race overall for the first time and then in 2007 – all of twenty years after Irish Independent’s win – Ireland secured the overall win again this time thanks to Ger O’Rourke’s Cookson 50 Chieftain from the Royal Western Yacht Club of Ireland in Kilrush.
