The Ryder 2019 Expedition with Swedish icebreaker Oden took place from early August to mid-September 2019 and included marine as well as land-based research. The overall scientific goal was to gain a better understanding of how climate affects the sensitive high Arctic environment. Chief Scientists at the Ryder expedition were Martin Jakobsson and Larry Mayer. Both were more than pleased with the expedition, where they managed to get to previously unexplored areas.
