An expedition in Tuvalu's waters is using a submersible to study the ocean - some parts of which have never been studied in-depth. The National Geographic Pristine Seas project is studying the health of Tuvalu's marine environments. The expedition is a partnership between Pristine Seas and Tuvalu government. Expedition leader Keiron Fraser said they will be deploying a range of scientific equipment in the sea and the tech will help them get an idea of the health of the ocean in that area.
"The leg we're on at the moment is a deep sea leg. So, a lot of the work that we're doing at the moment is centred around our submersible, the Argonauta, and that's a three-person submersible which is rated to go down to 1300 metres," he said. "We can put scientists in that with a driver to record scientific observations, count fish, look for species and things like that." Fraser said the submersible has a variety of tools on it, including a manipulator arm enabling the scientist to reach out and grab things.
