  • Sensitivity of Arctic Ocean Change to Background Mixing

    This project is motivated by recent findings showing the sensitivity of Arctic Ocean circulation to background deep-ocean diapycnal mixing. Mixing in the stratified ocean is related to internal wave energy, which tends to be low under the Arctic Ocean ice cover. Consequently, as ice cover declines background mixing may increase and, among other changes, bring more Atlantic Water heat to the surface to melt ice, a potentially important positive climate feedback. To understand the influence of background mixing and to improve models of the changing Arctic Ocean, we are taking advantage of the latest analysis techniques to examine existing internal…

  • Arctic Sea Ice Volume Anomaly

    The Arctic Sea Ice Volume Anomaly time series is calculated using the Pan-Arctic Ice Ocean Modeling and Assimilation System (PIOMAS) developed at APL/PSC.  Updates will be generated at approximately monthly intervals.

  • Variability and Trends in Antarctic Sea Ice

    This project will investigate, through modeling and data assimilation, the historical evolution of the Antarctic sea ice–ocean system from 1979 to the present to enhance our understanding of the large-scale changes that have occurred in the sea ice and the upper ocean in response to changes in atmospheric circulation.

  • The Arctic Ocean Model Intercomparison Project (AOMIP): Synthesis and Integration

    The AOMIP science goals are to validate and improve Arctic Ocean models in a coordinated fashion and investigate variability of the Arctic Ocean and sea ice at seasonal to decadal time scales, and identify mechanisms responsible for the observed changes.

  • Seasonal Ensemble Forecasts of Arctic Sea Ice

    Project investigators aim to improve upon the existing seasonal ensemble forecasting system and use the system to predict sea ice conditions in the arctic and subarctic seas with lead times ranging from two weeks to three seasons.

  • Projections of an Ice-Diminished Arctic Ocean – Retrospection and Future Projection

    Significant changes in arctic climate have been detected in recent years. One of the most striking changes is the decline of sea ice concurrent with changes in atmospheric circulation and increased surface air temperature.
