In December, 55 scientists from around the world set off from Cape Town, South Africa, for a three-month voyage around Antarctica. The Swiss Polar Institute is the lead sponsor of the Antarctic Circumnavigation Expedition (@ACE_Expedition), which will return to port in March.
In their Southern Hemisphere summer at sea, the group of scientists will study the impact of climate change on the Southern Ocean around Antarctica.
