Acoustic equipment that generates highly detailed maps of the sea floor has been used for the first time in the Antarctic to assess under-ice productivity.
Dr Alex Forrest from the Australian Maritime College in collaboration with Dr Vanessa Lucieer from the Institute for Marine and Antarctic Studies led a team of seven scientists and support staff to investigate conditions beneath pack ice and the first stages of marine life – algae – it supports. Algae plays a vital role in the polar ecosystem, forming the basis of the marine food chain that ultimately supports the mega-fauna of whales and seals.
