The Southern Ocean, the sea around Antarctica, could be described as extremely inhospitable but extremely important.
The whole planet depends on what happens in these particular waters, yet we know surprisingly little about what happens there. But now a team of scientists has deployed robots called Gliders in the Southern Ocean to stay and take measurements for almost a year. For the first time, we’re going to find out what happens during the winter, with carbon dioxide uptake and salinity, and so get more accurate data to put into different climate models to make more accurate predictions about the future.
