Call for Contributions: July Sea Ice Outlook Report

Call for Informal and Early Season Contributions to 2015 SIO
30 June 2015

The Sea Ice Prediction Network announces a call for Sea Ice Outlook (SIO) contributions to the July report—based on May and June data. The Sea Ice Outlook provides an open process for those interested in Arctic sea ice to share predictions and ideas about the monthly September minimum sea ice extent. Join a growing network of sea ice experts and contribute a pan-Arctic, regional, or informal Outlook.

The 2015 Sea Ice Outlook (SIO) - June Report received great media coverage by the Alaska Dispatch News. In an article, posted on 25 June, reporter Yareth Rosen provides a summary of the SIO goals and process, range of methods contributors used, links to Sea Ice Prediction Network (SIPN) and associated agencies, and the June median outlook for sea ice extent in September -- converted to square miles (1.93 million square miles).

We received a record 32 contributions using a range of methods including statistical, numerical models, trend-based estimates, and subjective information. The median Outlook value for September 2015 sea ice extent is 5.0 million square kilometers, and predictions fall in a range of 3.3 to 5.7 km2 (with the exception of one 0.98 km2 outlying estimate). This month’s report also includes a discussion about the 11 dynamical model contributions as well as sections on regional predictions and the current conditions of the sea ice.

The SIPN 2014 Sea Ice Action Team members Julienne Stroeve, Ed Blanchard-Wrigglesworth, Virginie Guemas, Stephen Howell, François Massonnet, and Steffen Tietsche published a discussion of the 2014 Sea Ice Outlook and forecasting skill of models that predict the extent and other characteristics of Arctic sea ice cover. Their article "Improving Prediction of Arctic Sea Ice Extent" is published in EOS.

29 May 2015

Announcing the recent release of new IceBridge and CryoSat-2 sea ice thickness data sets for the 2015 spring season.

The NASA IceBridge Sea Ice Freeboard, Snow Depth, and Thickness Quick Look data set is an evaluation product containing derived geophysical data products retrieved over the Arctic sea ice cover.

The NASA CryoSat-2 Sea Ice Freeboard, Thickness, and Snow Depth Quick Look product is an experimental sea ice thickness data set containing derived geophysical data products retrieved over the Arctic sea ice cover.

Sea Ice Concentration Fields for Operational Ice Forecasting

6 April 2015

NSIDC announces availability of the MASIE-AMSR2 (MASAM2) daily 4 km sea ice concentration, which is a prototype concentration product offering greater accuracy and higher resolution in ice concentration fields used to initialize an operational sea ice forecast model. MASAM2 is a blend of two other daily sea ice data products: ice coverage from the Multisensor Analyzed Sea Ice Extent (MASIE) product, at a 4 km grid cell size, and ice concentrations from the Advanced Microwave Scanning Radiometer 2 (AMSR2) at a 10 km grid cell size. This prototype MASAM2 product currently covers July 2012 through mid-November 2014, but it will become a daily product if there is demand for such a product.

Background

  • 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.
