Overview

For the third and last year of its mission, the Sedna IV has begun its journey back to its home port, the Magdalen Islands, which the vessel has reached after a detour in the Arctic. While there, Jean Lemire and his colleagues have measured the impact of environmental changes that took place since their first expedition twelve years ago, Mission Arctic. This return home will also bring them in several places along the St-Lawrence river and its gulf, an exceptional but fragile ecosystem that is changing very rapidly.
