Norwegian Ocean Climate Project
Principal Task 5:
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:
Variability and signal propagation from high resolution
- 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
"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
Coupled Ocean-Atmosphere Processes and European Climate
