Description of the session

Recent changes in the physical environments of the Subarctic and Arctic regions have been some of the largest in the world’s oceans. These have included warming seas and unprecedented changes in the Arctic sea ice. These changes have led to modifications to the marine ecosystems from plankton production to large marine mammals. Primary production in the northern regions has been increasing due to less ice and a longer production cycle. Several species of zooplankton, fish and marine mammals have been changing their distribution with most of these extending their geographic boundaries farther north. At the same time, the reduction of sea ice has produced hardships for walruses and polar bears. Such changes are also affecting fishing activities and indigenous communities.

The objectives of the session are:

  1. to highlight the research of ESSAS,
  2. to document ecosystem changes in the Subarctic and Arctic,
  3. to present improved understanding of ecosystem processes,
  4. to generate future ecosystem scenarios under climate change and
  5. to examine the links between the natural and human systems.
