    Principal Task 5:
    Variability and signal propagation from high resolution information

    The main objective is to improve our present understanding and description of seasonal and interannual variability of the water masses that flow into and within the Nordic Seas and Arctic Ocean. The variability of the extent and fluxes of sea ice will also be investigated. Available information with a high spatial resolution from simulations and satellites from the past 20 years, and in situ observations of ocean currents, hydrography, ice coverage etc., will form the basis for this study. The key questions that will be addressed in this task are:
  • Does teleconnections by oceanic pathways give rise to significant interannual variability in the AW inflow, or is the local wind forcing always the controlling mechanism for such variability?
  • By quantitative amounts, what is the seasonal and interannual variability in the AW inflow along its eastern and western branches?
  • By quantitative amounts, what are the seasonal and interannual variability, and trends, in the ice and ocean variables and fluxes of the Arctic Ocean?
  • What is the seasonal and interannual variability of the position and strength of the front between Atlantic Water and Arctic Water in the Nordic Seas?

  • In the first phase (2000-2002) of the coordinated project, task 5 contributes to the project's second overall objective:
    "improve and enhance our understanding of ocean and ice processes related to climate, and mechanisms causing significant variability in the hydrography, circulation and ice cover in the northern seas".

    Some of the results that are presented here are preliminary, and should be considered as work in progress.
