Explore the comprehensive analysis of Arctic sea ice dynamics in the September 2009 report. Dive into the changing landscape of sea ice age, atmospheric climate impacts, and anomalies. Understand the loss of multi-year ice and its implications on the larger climate system. Gain insights from the collaborative efforts of 15+ research groups and the outlook for 2010. Prioritize winter 2010 goals for rapid communication and defining observation strategies with a focus on ocean heat content and ice type reconnaissance.

2009 OUTLOOK was as a success 15+ GroupsWhile 2009 was 3rd lowest summer extent, fall freeze up was very late. Multi-year sea ice very low relative to 2004 (Kwok). Arctic still behaving with extremesContinue for 2010, met the goal of rapid communicationPriority for winter 2010: Work with other groups to define priority observations in support of OUTLOOK- ocean heat content, visual recon of ice types
