This page makes use of JavaScript to permit display of interatively selected months of ice cover. The data are from Chapman, W. L. and J. E. Walsh, Long-Range Prediction of Regional Sea Ice Anomalies in the Arctic, Weather and Forecasting, 6, pp 271-288, 1991. The data are available from the The National Snow and Ice Data Center. One important feature is that these fields are not averages in any sense. They are representations of the sea ice cover at the end of the named months.
