The schooner has travelled 62, 000 miles across the Atlantic, Pacific, Antarctic and Indian oceans investigating the effects of global warming on biodiversity and marine life, particularly focusing on marineplankton.
The ocean absorbs close to 26 per cent of atmospheric carbon dioxide emissions which is provoking acidification that is already threatening some varieties of plankton and poses a threat to the entire marine food chain and dependant socio-economic activities.
It can adversely affect forests and crops, and is also linked with damage to plankton, the microscopic creatures at the bottom of the marine food chain.
