New IABP Web Pages

Summary buoys were reporting in June buoys were deployed from June – September buoys were reporting in September buoys were reporting in April We plan to deploy 120+ buoys at 80+ separate locations in More details can be found at Coordinator needs to collect buoy data from DAMOCLES projects to include in IABP databases. 7.Please send comments on our new web pages. I would like to add more content featuring the full breadth of the IABP. 8.Big Issue: Larger area of younger, thinner ice has taken a toll on the IABP array, highlighting the need for buoys which can survive in open water, survive freeze up, and pack ice conditions (i.e. seasonal ice buoys), especially in the Eurasian Arctic.
