Scientist Tim O'Hara will be coming in to talk about leading the first deep-sea exploration voyage upon The Investigator (the CSIRO's marine research vessel) from Launceston to Brisbane. On this voyage, Tim will be leading an international team of 40 scientists for a 31-day scientific expedition, it will be the first survey in Australia to examine marine life down to the depth of 4km. The expedition is an important one because the data that is gathered will be crucial to understanding deep-sea habitats so that we can protect them against the challenges faced by climate change, pollution and more.
