Researchers from Trinity College Dublin are among a team of marine scientists that have used tiger sharks to discover the world’s largest seagrass ecosystem.

According to The Irish Times, the team attached cameras to the sharks who inhabit the enormous network of seagrass meadows in the Bahamas and help maintain its health by controlling numbers of grazing marine wildlife like turtles and manatees.

The video footage provided a never-before-seen look into an ecosystem that’s crucially important for carbon sequestration, among other things, while also helping the scientists to map the area which amounts to as much as 92,000 square kilometres.

“This is an exciting and important discovery for a range of reasons,” said Nicholas Payne, assistant professor in Trinity’s School of Natural Sciences and co-author of the research published in the journal Nature Communications.

“Here in Ireland, we have a huge coastal area that likely supports significant seagrass ecosystems,” he added.

History of the INSS

Set up by Alistair Rumball in 1978, the sailing school had very humble beginnings, with the original clubhouse situated on the first floor of what is now a charity shop on Dun Laoghaire's main street. Through the late 1970s and 1980s, the business began to establish a foothold, and Alistair's late brother Arthur set up the chandler Viking Marine during this period, which he ran until selling on to its present owners in 1999.

In 1991, the Irish National Sailing School relocated to its current premises at the foot of the West Pier. Throughout the 1990s the business continued to build on its reputation and became the training institution of choice for budding sailors. The 2000s saw the business break barriers - firstly by introducing more people to the water than any other organisation, and secondly pioneering low-cost course fees, thereby rubbishing the assertion that sailing is an expensive sport.
