First up on the podcast, freelance science journalist Sofia Quaglia talks about her visit to the Galápagos archipelago and how researchers there are working to restore the islands to their former ecological glory. Next on the show, Antarctica’s deep ice coating obscures the hills and valleys on its surface, making the continent’s response to climate change one of the biggest unknowns in predicting sea level rise over the next century. Helen Ockenden, a glaciologist at Grenoble Alpes University, joins the podcast to discuss how her team used satellite imagery and the physics of ice flows to fill in the missing details of Antarctica’s subglacial surface.
