What is The Polar Oceans and Their Role in Shaping the Global Environment (Johannessen/The Polar Oceans and Their Role in Shaping the Global Environment) about?
The variations of AfCO2 (difference of sea surface and atmospheric carbon dioxide fugacities) and air-sea CO2 fluxes are described in the western Indian sector of the Southern Ocean. The study is based on measurements made continuously with an Infrared technique during two cruises in January-April 1991 and one recent cruise in February 1993. We also compare AfCO2 distributions observed in February 1987 and February 1993 at 30°E. Large AfCO2 variations have been observed, most of which can be related to dynamical variability and/or local biological activity, near the ice edge, the antarctic divergence, the Polar Front Zone or local change in topography (e.g. Kerguelen Plateau). Near the pack ice, clear relationships are found between low AfCO2 (CO2 sink area) and high chorophyll-a concentrations. A significant CO2 source region has been found in February 1993 centered on the antarctic divergence. South of the Polar Front Zone, fCO2 decreases strongly; this signal was also found in 1987 and 1991 and can be related to high chlorophyll signal. In the region of the Kerguelen Plateau AfCO2 spatial variability is very high. Neutral, source or sink conditions can be found at small scale (1
