Emerging Dynamics of the Marginal Ice Zone

The "Emerging Dynamics of the Marginal Ice Zone" is an Office of Naval Research (ONR) Departmental Research Initiative, or DRI. The goal of this five-year (FY12-FY16) DRI is to improve the knowledge and understanding of the physics of the retreating summer ice edge and MIZ in the Beaufort and Chukchi seas.

The main field experiment occurred between March and October 2014 in the Beaufort Sea north of Alaska, and the DRI has now entered the data analysis, synthesis and publication phase. Proposals for additional research on the marginal ice zone are likely to be given a lower program priority than other topics until this DRI concludes at the end of FY16.

Complete information about the MIZ DRI is available at the University of Washington Applied Physics Laboratory project website. The titles of MIZ DRI awards are listed below, and annual reports are available via the following links: FY12 | FY13 | FY14 | FY15
