Networking scientists and stakeholders to improve sea ice prediction in a changing Arctic

Sea Ice Prediction Network


SIPN Leadership Team Member Provides Testimony to U.S. Senate Committee

20 March 2015

On Thursday, 5 March 2015 Cecilia Bitz provided the U.S. Senate Energy and Natural Resources Committee with testimony about Arctic research opportunities. Her comments featured the Sea Ice Prediction Network (SIPN) as an example of exciting new work that could deliver even more relevant information to policy makers with further investments. Her comments are recorded from 1:26 to 1:31 in the archived video.

Webinar Archive Available

6 March 2015

The archive is now available for the Sea Ice Prediction Network (SIPN) webinar on "Sea Ice Modeling: Characteristics and Processes Critical for the Radiation Budget," presented by Elizabeth Hunke, Los Alamos National Laboratory. The archive includes video of the webinar, the presentation slides, and a list of webinar participants.

10 February 2015

The Polar Climate Predictability Initiative (PCPI) announces a call for abstracts and registration for the Sea Ice Prediction Workshop 2015. This workshop will discuss polar climate variability and predictability on seasonal to decadal timescales. Presentations on understanding the causes of of inter-annual polar climate variability, as well as idealised predictability studies, and operational forecasts are welcome. The workshop will convene 8-10 April 2015 at the University of Reading, United Kingdom. For more information contact Ed Hawkins (e [dot] hawkins [at] reading [dot] ac [dot] uk).

The Sea Ice Prediction Network (SIPN) announces the 2014 Sea Ice Outlook (SIO) Post-Season Report! The SIO provides an open forum for researchers and others to share and discuss predictions of Arctic sea ice through monthly reports in the summer and a post-season analysis. The post-season report includes analysis of the relative skill of various Arctic sea ice prediction models and methods and an expanded focus this year on the spatial pattern, probability, and ice-free dates for specific regions.

An archive of the Sea Ice Outlook: Post-Season Discussion webinar, held on 9 October 2014, is now available. The webinar, hosted by the Sea Ice Prediction Network (SIPN), focused on post-season analysis and discussion of the 2014 Sea Ice Outlook (SIO) and provided 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.

  • 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) is developing 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.
