Sea Ice Outlook: 2013 Post-Season Report
POST-SEASON REPORT
HIGHLIGHTS & TAKE-HOME POINTS
Loss of summer Arctic sea ice took a pause in 2013 with September 2013 having the 6th lowest extent since satellite observations began in 1979: 5.4 million square kilometers, based on National Snow and Ice Data Center (NSIDC) estimates. The seven lowest minimum ice extents have occurred in the last seven years, 2007-2013.
Sea Ice Outlook: 2013 July Report
Summary
We appreciate the continuing contributions to the July Outlook (using June data). We received 21 Pan-Arctic responses for the September 2013 Arctic mean sea ice extent with a median value of 4.0 million square kilometers and the quartile values are 3.8 and 4.6 million square kilometers (Figure 1). The range of estimates was 3.2 to 5.9 million square kilometers. For comparison, the June 2013 median was 4.1 million square kilometers and the July median from 2012 was 4.6 million square kilometers.
Sea Ice Outlook: 2013 June Report
Summary
With 23 pan-arctic Outlook contributions, an increase over the last two years (thank you!), the June Sea Ice Outlook projects a September 2013 arctic sea extent (defined as the monthly average for September) median value of 4.1 million square kilometers, with quartiles of 3.8 and 4.4 million square kilometers (Figure 1).
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.
