Sea Ice Outlook: 2009 Summary Report
Pan-Artic Summary
Status and Disclaimer
A request was sent to the contributors of the 2009 SEARCH Sea Ice Outlook to summarize the 2009 arctic sea ice season. A key question was: were there systematic or physical changes that contributed to a greater observed sea ice extent this year or was it within the range of natural variability? We appreciate all participants and reviewers who contributed their time to making the 2009 Outlook effort a success for the second year.
Sea Ice Outlook: 2009 Early September Update
As suggested by the 15-day forecast from early August (discussed in the August Outlook report), the weather pattern for August completely changed from the pattern of June and July, decreasing the chance of a record September sea ice loss for 2009. The September minimum is likely to be around 5.0 million square kilometers, compared to around 4.5 million square kilometers for 2008 and 4.1 million square kilometers for 2007. It should be noted that this 2009 extent would still be well below the average for 1979–2000 of 6.7 million square kilometers.
Sea Ice Outlook: 2009 August Report
SUMMARY
The outlook for arctic sea ice in September 2009, based on July data, indicates a continuation of low pan-arctic sea ice extent and no indication that a return to historical levels will occur.
The August Sea Ice Outlook Report is based on a synthesis of 13 pan-arctic contributions (plus nine updates from participating regional groups) utilizing a range of methods.
Sea Ice Outlook: 2009 July Report
SUMMARY
The outlook for arctic sea ice for September 2009, based on June data, indicates a continuation of low pan-arctic sea ice extent and no indication that a return to historical levels will occur.
The July Sea Ice Outlook Report is based on a synthesis of 16 individual pan-arctic estimates (plus nine regional contributions) utilizing a range of methods.
Sea Ice Outlook: 2009 June Report
SUMMARY
The outlook for arctic sea ice for September 2009, based on May data, indicates a continuation of low pan-arctic sea ice extent and no indication that a return to historical levels will occur. The June Sea Ice Outlook Report is based on a synthesis of 15 individual pan-arctic estimates (plus six regional contributions) utilizing a range of methods; two additional pan-arctic contributions provide background information on recent sea ice observations.
Sea Ice Outlook: 2008 July Report
Summary
The outlook for the pan-arctic sea ice extent in September 2008, based on July data, indicates a continuation of dramatic arctic sea ice loss. The July Sea Ice Outlook report is based on a synthesis of 22 individual projections utilizing a range of methods. Projections based on July data show no indication that a return to historical sea ice extent will occur this year.
Sea Ice Outlook: 2008 June Report
The outlook for the pan-arctic sea ice extent in September 2008, based on June data, indicates a continuation of dramatic sea ice loss. The June Sea Ice Outlook report is based on a synthesis of 17 individual projections, utilizing a range of methods. Projections based on June data are similar to those of the May report, with no indication that a return to historical sea ice extent will occur this year.
Sea Ice Outlook: 2008 May Report
The May Sea Ice Outlook report for the September 2008 sea ice extent is based on a synthesis of 19 individual outlooks from the international arctic science community. The outlook for the pan-arctic sea ice extent in September 2008 indicates a continuation of the recent trend of sea ice loss.
