CASES 2003-04: the expedition of the Amundsen

Building on the two highly successful expeditions of 2002, the main thrust of the program was the 2003-04 one-year expedition of the Canadian research icebreaker, the Amundsen. This field program consisted of 4 distinct phases; 1) the fall of 2003, where operations were conducted in open water from the Amundsen ; 2) the overwintering, when the ship was ‘’frozen’’ in the Franklin Bay, where biological sampling was made from the ship’s moonpool and from ice stations; 3) the spring-summer 2004 ice break-up, where open water sampling operations were resumed and; 4) the fall 2004 (September), where completion of the moorings operations and opportunistic biological sampling occurred for a supplementary 18 days on board the CCGC Sir Wilfrid Laurier. Colossal amounts of data were obtained over the one year cycle that will require years of analyses and the implication of a large number of scientists, students and research personnel.

To learn more about the 2003-04 expedition

When including the expeditions of 2002, this plan guarantees a 3-year interannual comparison of the ecosystem's maturity in response to sea ice as well as oceanic and atmospheric forcing processes. It also represents the first ever, year-round, highly integrated, multidisciplinary study of an Arctic shelf ecosystem, including a segment of the circum-Arctic flaw polynya system.

The final experimental plan was adopted after consultations with the Inuvialuit communities that border this fragile ecosystem. The progress report summarises the scientific activities of the CASES Network from 2002 to 2004.
