What specific gap did the 2011 Agreement on Cooperation on Aeronautical and Maritime Search and Rescue in the Arctic (agreed by the eight Arctic Council states) address?

A. It created a single, unified international rescue fleet under direct United Nations command, replacing all national SAR services in the Arctic

B. It formally divided the Arctic region into defined search and rescue areas of responsibility allocated to specific states, and established a framework for cooperation, resource-sharing, and coordination between those states' rescue services — addressing the fact that, before this agreement, large parts of the Arctic lacked clearly defined SAR responsibility and coordination structure, despite growing shipping, fishing, and tourism activity in the region

C. The agreement only addresses aeronautical search and rescue and has no maritime application whatsoever

D. The agreement is purely advisory with no defined areas of responsibility or binding cooperative framework between signatory states

A. There is no meaningful difference in SAR governance structure between the Arctic and Antarctic regions

B. No — the 2011 Agreement is specific to the Arctic and the eight Arctic Council states; the Antarctic has a different governance framework entirely (the Antarctic Treaty System), and search and rescue coordination there, as illustrated by the Akademik Shokalskiy case, relies on a different, less formally pre-allocated structure involving whichever capable vessels and coordination centres are available in the region

C. The 2011 Agreement applies equally and identically to both Arctic and Antarctic waters under a single unified polar SAR framework

D. The Antarctic has a more formally developed area-of-responsibility SAR agreement than the Arctic, reversing the actual relationship

A. Area of responsibility designation has no practical effect on which state coordinates a response, serving only a symbolic or political function

B. Area of responsibility is determined separately for every individual incident with no pre-agreed allocation existing in advance

C. It determines which state's rescue coordination centre takes the lead role in coordinating the response to an incident within that area — this does not mean only that state's own assets must be used; the agreement also includes provisions for requesting assistance from other parties' resources when needed, but it establishes clear initial coordination responsibility rather than leaving this ambiguous

D. Only the designated state's own vessels and aircraft may ever be used to respond to an incident, with no cross-border assistance possible under any circumstances
