A team of three Tristan Islanders (Head of Fisheries James Glass, Norman Glass and Rodney Green) joined biologist divers (Sue Scott, Rohan Holt and Holly Latham) to travel aboard MV Edinburgh to carry out a successful diving survey of the marine life around Gough Island. The expedition left Tristan on 24th January and arrived at Gough the following day. The team completed many dives surveying various locations in depths to about 30 metres. The work was part of a two-year marine and fisheries project funded by Darwin Plus and the RSPB which also part-funded a new rigid-hulled inflatable built to the fisheries department specifications, and which proved ideal as a diving platform in the waters around Gough. This 8.5m RIB named Jasus tristani has enable the fisheries department to work independently. It was the first dives made by Tristan Islanders at Gough Island. MV Edinburgh departed Gough on 14th February and returned to Tristan the following day. |
