The Barents Sea is a high-latitude ecosystem and one of the most productive regions over the World Ocean. In this issue, several studies on the carbon cycle, the primary and secondary production, and more specifically the seasonal variations of these processes, are presented. A new Arctic Research Programme, the Arctic Light and Heat Programme, is described. The main objectives and tasks of the programme are research on the seasonal C-flux variability and some significant processes and components along a south-north gradient in the Western Barents Sea. The focus lays in particular on the marginal ice zone and the ice-covered northernmost regions. The present investigation focussed upon a number of basic elements: 1) Nutrients, suspended biomass and pico- to mesoplankton; 2) Vertical flux in the upper 200 m; 3) CO2 uptake dynamics; 4) Grazing egg production and faecal pellet production.
