Mapping the Indian Ocean Mysteries

The video discusses the mapping of parts of Australia's Indian Ocean, revealing underwater volcanoes and shipwrecks. This mapping was part of the search for the missing flight MH370, which remains unsolved. The search used advanced technology, including an autonomous underwater vehicle called 'The Fish', to map the seafloor in detail. The data collected has potential applications in climate change research and tsunami prediction, although only a small portion of the Indian Ocean has been mapped.

What was one of the main purposes of mapping parts of Australia's Indian Ocean?
