The Sea Ice Outlook (SIO) organizers are soliciting pan-arctic and
regional outlooks for the August report (based on July data). We
encourage past and new contributors to participate. Contributors who
provided Outlooks last month may submit brief updates. The deadline for
both pan-arctic and regional outlooks is Friday, 5 August 2011.

ALL Outlook submissions (Regional and Pan-Arctic) should be sent
directly to Helen Wiggins, ARCUS, at: helen [at] arcus.org, with the
following subject lines, as relevant:

PAN-ARCTIC OUTLOOK - [YOUR LAST NAME]

REGIONAL OUTLOOK - [YOUR LAST NAME]

OUTLOOK FOR BOTH REGIONAL AND PAN-ARCTIC - [YOUR LAST NAME]

A Word document is preferred for ease of formatting to PDF files and
extracting images for the website - we will not edit your individual
submission and will not post your Word documents.

SUBMITTING A PAN-ARCTIC OUTLOOK
Pan-arctic 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).

2. Methods / Techniques
   Provide the type of estimate (heuristic, statistical, ice-ocean model
   ensemble runs, etc.).

3. Rationale
   Include a short paragraph on the physical rationale for the estimate.

4. Executive Summary
   Provide a short paragraph that summarizes your outlook contribution in
   two or three sentences.

5. Estimate of Forecast Skill (if available)
   If possible, please include any estimates of forecast skill,
   uncertainty, or error associated with your prediction. This year, we
   will add error estimates to the summary bar chart of outlook estimates,
   as appropriate.

This year we would also like to include a brief discussion of ice
thickness in the monthly reports, so please include any relevant
information on ice thickness (or age), if available.

SUBMITTING A REGIONAL OUTLOOK
Regional Outlook contributions should include:

1. Region of Interest
   While more specific sub-regions may be identified, at a minimum, please
   specify which of the following the outlook applies to:

Arctic Regions:

- Beaufort-Chukchi Seas
- East Siberian - Laptev Seas
- Kara-Barents-Greenland Seas
- Canadian Arctic Archipelago and Nares Strait
- Hudson Bay
- Sea of Okhotsk
- Bering Sea

Shipping Routes:

- Northwest Passage
- Northeast Passage (Northern Sea Route)
- Arctic Bridge (Murmansk - Churchill)

2. Sea Ice Parameter
   Provide a regional pattern or a single value estimate of phonological
   stages (i.e., melt onset, freeze onset, break-up and freeze-up dates,
   length of open water season) or monthly ice concentration, ice area, and
   ice extent. Please indicate whether you expect ice conditions to be
   similar, lighter (i.e., lower ice concentrations, earlier melt onset,
   earlier break-up, later freeze-up), or heavier (i.e., greater ice
   concentrations, later melt onset, later break-up, earlier freeze-up)
   than those of summer 2010.

3. Outline of Methods / Techniques
   Provide the type of estimate (heuristic, statistical, ice-ocean model,
   traditional knowledge, etc.) with a brief description of the methodology
   and a short paragraph describing the physical rationale for the
   estimate.

4. Estimate of Forecast Skill
   If possible, please include any estimates of forecast skill,
   uncertainty, or error associated with your prediction.

5. Improving Outlook Detail and Accuracy (Optional)
   What information would be needed to improve the level of detail provided
   in your Regional Outlook or increase the accuracy/confidence in your
   prediction?

Pan-Arctic and Regional contribution deadline: Friday, 5 August 2011.
