A team of Scientists led by Dr. Louise Allcock, NUI Galway sets sail onboard the RV Celtic Explorer 13th April 2012 to investigate biodiversity on the Whittard Canyon System.
Whittard Canyon is a huge canyon system that spans Irish, UK and French waters along the Atlantic margin. This survey will take place in the Irish territory where the Continental shelf drops down to depths beyond 3000 m. The Marine Institute’s Holland 1 Remotely Operated Vehicle (ROV) will be deployed to explore the steep canyon walls where biodiversity is greatest because of the fast currents there. Whittard has been explored before, but the system is so vast that some areas are still unsurveyed.
The multidisciplinary team on board will be looking for corals and sponges, which can be found in extensive reefs at some depths. A feature of species growing attached to the seafloor is the production of chemicals, thought to deter grazing and overgrowth by other animals. There is significant scientific and commercial interest in the novelty of these chemicals for medical applications. Material previously collected for the Irish Marine Biodiscovery Programme has shown activity against some cancer cell lines, the first step in potentially developing new treatments. Material collected on this cruise will be examined in antibacterial and anti-cancer assays as part of the National Marine Biodiscovery Programme in NUI Galway, UCC and the Marine Institute.
The survey will also carry out detailed surveys of the canyon system in collaboration with onboard taxonomists from across Europe, who are experts in identifying deep sea marine organisms. Biogeochemists from Trinity College Dublin will study the processing of material in the benthic ecosystem, with oceanographers from Galway following the transport of sediment and planktonic production to deeper waters. These studies will improve the understanding of the canyon ecosystem and the links between surface and deep waters.
The scientists will be blogging throughout the survey and you can follow their progress athttp://scientistsatsea.blogspot.com
This research survey and the Beaufort Marine Research Award are carried out under the Sea Change strategy with the support of the Marine Institute and the Marine Research Sub-programme of the National Development Plan 2007–2013. The Beaufort award in Marine Biodiscovery is a consortium between NUI Galway, UCC and Queen’s University Belfast. The Ship-Time Programme provides access to the National Research Vessels (Celtic Explorer / Celtic Voyager) for research organisations based in Ireland.
