SAVE THE DATE: The Sea Ice Prediction Network (SIPN) announces an open webinar focused on post-season analysis and discussion of the 2014 Sea Ice Outlook (SIO). This webinar will provide a venue for discussion of the 2014 SIO, including processes that influenced sea ice melt this year and a review of the differing approaches to predicting the sea ice minimum extent. The webinar is open to all interested participants, including sea ice researchers, students, decision-makers, and others. This webinar is scheduled for Thursday, 9 October 2014 from 11:00 a.m. to 12:00 p.m. AKDT.

The Sea Ice Prediction Network (SIPN) announces a call for contributions to the August Sea Ice Outlook report. Please see the guidelines for submitting regional and pan-Arctic outlooks. A variety of perspectives, from advanced numerical models to qualitative perspectives from citizen scientists, are welcome.

July Sea Ice Outlook

23 July 2014

Announcing the July Sea Ice Outlook report! We received 28 pan-Arctic contributions and three regional contributions. The median Outlook value for September 2014 sea ice extent is 4.8 million square kilometers with quartiles of 4.4 and 5.0 million square kilometers. The report includes a brief executive summary, comments on modeling outlooks and on regional predictions, current conditions, and the individual Outlook contributions.

SIPN Team member Cecilia Bitz announces a call for abstracts for an AGU Session: Processes and Predictability (Session #2392). Presentations that examine the processes that govern seasonal to multidecadal polar climate variability, identify sources of polar climate predictability, and characterize uncertainty in polar climate prediction are welcome. The session seeks to connect the community of atmospheric, oceanic, and cryospheric scientists working on topics relevant to the new Polar Climate Predictability Initiative of the World Climate Research Program. It will convene during the AGU Fall Meetings in San Francisco 15-19 December 2014.

The first arctic Sea Ice Outlook report of the year has been published, and we had a record number of pan-arctic contributions! The median Outlook value for September 2014 sea ice extent is 4.7 million square kilometers. Only three outlooks this are above the 2013 observed September extent. This full report includes a brief summary, comments on modeling outlook, current conditions, key statements from all the Outlook contributions, and links to download the outlook contributions.

  • Decline in the extent and thickness of Arctic sea ice is an active area of scientific effort and one with significant implications for ecosystems and communities in the Arctic and globally.

  • Forecasting for seasonal timescales (i.e., the summer and into fall) is of particular interest to many stakeholders since many activities that take place in the arctic are planned over the summer months, and many species are sensitive to the behavior of summer sea ice.

  • However, seasonal forecasting is particularly challenging due to the variable nature of weather and ocean behavior over that timescale as well as current limits to data and modeling capabilities.

  • SIPN builds and expands on the Sea Ice Outlook project.

The Sea Ice Prediction Network (SIPN)—to be launched over the fall 2013—will develop a collaborative network of scientists and stakeholders to advance research on sea ice prediction and communicate sea ice knowledge and tools.

Project Objectives

  1. Coordinate and evaluate activities to predict sea ice
  2. Integrate, assess and guide observations
  3. Synthesize predictions and observations
  4. Disseminate predictions and engage key stakeholders

Join the Network

We are also inviting project collaborators and network participants at this time. Action Teams will be formed around the project objectives and will provide opportunities for collaboration. If you are interested in participating in the network—through participation in an action team, modeling/prediction activities, as a data provider, or as a stakeholder—you can join the network by emailing any member of the Network Team or by filling out the interest form at the bottom of this page.
