Expedition Glacialis is a team of scientists aboard a 43' custom steel Koopmans sailboat. Virginie Wyss, Matthew Ryle, Arnaud Conne, and Richard Mardens are collecting data on wildlife, plastics, and the chemistry of the ocean. Their project has taken them to Greenland, where they were when we spoke. We talk about the magic of Greenland, the difficulties and rewards of sailing in the arctic, their boat Atlas, dressing for the cold, heaters, safety gear, heavy weather strategies, wildlife, the marriage of art and science, preparing for the journey, sailing with a purpose, citizen science, micro and macro plastics, listening to whales, and the crew's favorite species.
