Annually, 18 million km2 of ice grows and melts around Antarctica. We have limited knowledge of the ocean within, and at the edge, of this enormous sea-ice impacted domain of the Southern Ocean. The surface ocean processes are poorly quantified due to a lack of observations made at the right time and space scales. These scale gaps have been recognised by the science community as a key link towards improving our understanding of the sensitivity of the Southern Ocean to climate change. At Polar Gliders we aim to observe the full seasonal cycle of the upper ocean in the MIZ near the Greenwich Meridian.
