Call for SEARCH Sea Ice Outlooks - July Report

June 30, 2009

Call for Sea Ice Outlooks September 2009 Sea Ice Outlook: July Report Study of Environmental Arctic Change (SEARCH) Outlook Submission Deadline: Saturday, 4 July 2009 For further information about the Sea Ice Outlook, please go to: http://www.arcus.org/search/seaiceoutlook Or contact: Jim Overland Email: james.e.overland@noaa.gov Or: Hajo Eicken Email: hajo.eicken@gi.alaska.edu -------------------- Organizers of the Study of Environmental Arctic Change (SEARCH) Sea Ice Outlook (SIO) are now soliciting outlooks for the July report. Regional Outlooks are especially encouraged. The deadline for submissions is Saturday, 4 July 2009. Further information about the SIO is available at: http://www.arcus.org/search/seaiceoutlook. SUBMITTING AN OUTLOOK Outlook contributions should include: 1. Extent Projection Provide a sea ice projection for the September monthly mean arctic sea ice extent (in million square kilometers). For reference, the arctic sea ice monthly mean extent for September 2008 was 4.7 million square kilometers; in September 2007, it was 4.3 million square kilometers. 2. Methods / Techniques Provide the type of estimate (heuristic, statistical, ice-ocean model ensemble runs, etc.). 3. Rationale Please include a short paragraph on the physical rationale for the estimate. The organizers are also interested in perspectives on ice/atmosphere dynamics. Outlook submissions should be sent via email, with the word OUTLOOK in the subject line, to: Jim Overland Email: james.e.overland@noaa.gov REGIONAL OUTLOOK SUBMISSIONS Regional Outlook submissions should include: 1. Region of Interest While more specific sub-regions may be identified, at a minimum, please specify which of the five main arctic regions the outlook applies to: - Bering-Chukchi-Beaufort Seas; - Northwest Passage (please specify the specific route); - Northeast Passage (Northern Sea Route); - Barents-Greenland Seas; or - High Arctic (north of 85N). 2. Estimate of the Ice Season Evolution Provide an estimate of the ice season evolution (including prevalent or expected ice types) from now to the time of the summer sea ice minimum in September. Please indicate whether you expect ice conditions to be lighter or heavier than those of last summer (2008). Ice condition assessment categories are: i. Light Ice Conditions - Melt onset is earlier than normal, ice retreat is more rapid than normal, and / or ice concentrations over the course of the season are below average. Ideally, the outlook would be more specific about which of these applies and also indicate whether the assessment references a specific activity, such as different types of ship traffic, subsistence hunting, etc. ii. Medium Ice Conditions - Neither heavy nor light ice concentrations. iii. Heavy Ice Year - Melt onset is later than normal, ice retreat is slower than normal, and / or ice concentrations over the course of the season are above average. Ideally, the outlook would be more specific about which of these applies. 3. Assessment of the Timing of Freeze-up i. What is your general assessment of the timing of freeze-up? ii. Will the onset of ice formation in the fall be earlier or later than normal? iii. Are any anomalies anticipated in the regional pattern of freeze-up? 4. Outline of Methods / Techniques (Optional) i. What is the regional outlook based on (statistical model, heuristic approach, traditional knowledge, etc.)? 5. Improving Outlook Accuracy (Optional) i. What information would be needed to improve the accuracy of your Regional Outlook? Regional Outlook submissions should be sent via email, with the words REGIONAL OUTLOOK in the subject line, to: Hajo Eicken Email: hajo.eicken@gi.alaska.edu The submission deadline for the July report is Saturday, 4 July 2009.
