Over the course of a month at sea, an international team of scientists attempt to gain insights into the Earth’s last deglaciation period. Around 15,000 years ago, the western margin of the Greenland Ice Sheet destabilized and then retreated at an accelerated rate, but the reasons for this rapid deglaciation remain unclear. The Baffin Bay Deglaciation Experiment (BADEX) seeks a greater understanding of this paleoclimate event, in the hopes of gaining deeper insights into climate change today.
