The Arctic Sunrise will be touring Patagonia and Chile for 4 weeks, investigating the extent to which the glaciers and ice-fields there are disappearing. The research team's findings confirm that a number of large glaciers, such as the San Quintin and Upsala glaciers, part of the Northern and Southern Patagonian ice-fields, have significantly thinned and have retreated several kilometres in recent years.
