Sea Ice Outlook: 2011 August Report
Summary
Many thanks to all contributors to the August Sea Ice Outlook. We received 21 responses for the Pan-Arctic report (Figure 1), with estimates in the range of just below 4.0 million square kilometers to as high as 5.4 million square kilometers for the September arctic mean sea ice extent. As in the July Outlook, the median value was 4.6 million square kilometers with quartile values of 4.3 and 4.6 million square kilometers, a rather narrow range.
Sea Ice Outlook: 2011 July Report
Summary
Thank you to all contributors of the July Sea Ice Outlook. We received 16 responses for the Pan-Arctic report (Figure 1), with estimates in the range of 4.0 to 5.5 million square kilometers for the September arctic mean sea ice extent. The median value was 4.6 million square kilometers; the quartile values were 4.3 and 4.7 million square kilometers, a rather narrow range given the intrinsic uncertainty of the estimates on the order of 0.5 million square kilometers.
Sea Ice Outlook: 2011 June Report
Pan-Arctic Summary
The 2011 June Outlook suggests a modest decrease for summer 2011. With 19 responses for the pan-arctic (and 7 for the regional outlook), including several new contributors, the June Sea Ice Outlook projects a September 2011 arctic sea extent median value of 4.7 million square kilometers (Figure 1). This compares to observed September values of 4.7 in 2008, 5.4 in 2009, and 4.9 in 2010.
Sea Ice Outlook: 2010 Post-Season Report
Post-Season Report
INTRODUCTION
A request was sent to the contributors of the 2010 SEARCH Sea Ice Outlook to summarize the 2010 arctic sea ice season. We asked:
Sea Ice Outlook: 2010 August Report
Pan-Arctic Summary
For the August Outlook, a total of 18 contributions were received—16 from the scientific community and 2 from the general public. The mean prediction for the September minimum, excluding the two contributions from the general public, is 4.9 +/- 0.51 million square kilometers. This is a slight increase from the July Outlook of 4.8 +/- 0.62 million square kilometers and reflects in part the slowdown of ice loss observed in July.
Sea Ice Outlook: 2010 July Report
Pan-Arctic Summary
The July Outlook for arctic sea ice extent in September 2010 shows some notable adjustments from the June Outlook, with both downward and upward revisions from last month.
Sea Ice Outlook: 2010 June Report
Pan-Arctic Summary
The June Outlook for arctic sea ice in September 2010 shows reasonable arguments for either a modest increase or decrease in September 2010 sea ice extent compared to the last two years (5.4 million square kilometers in 2009 and 4.7 million square kilometers in 2008). However, it is important to note that the June 2010 Outlook indicates a continuation of the overall trend in long-term loss of summer arctic sea ice, with no indication that a return to historical levels of the 1980s/1990s will occur.
