Ocean-colour data are also being used i [...] Other applications include studies of cross-domain fluxes and interactions: ocean-atmosphere and land-ocean fluxes of carbon, ocean-cryosphere interactions and climate impact on the polar ecosystems. It must [...] land to oceans and the amount of carbon going to lake sediments is in the same order of magnitude than the flux of carbon from land system to oceans.

Changes in the Arctic weather can also have a substantial impact on the global climate, not least of all because of the shear ex- panse of the Arctic coastal region.

In the summer months, however, waves can
