In February and April 2000, in the Southern Ocean between Africa and Antarctica, concentration of chlorophyll (Cchs) in the surface layer was not high (0.1-0.3 mg/m**3). Zones of increased Cchs values (0.6-2.0 and over 2.0 mg/m**3) were located between the Southern Subtropical and Subantarctic fronts, near the Polar front, and to the south of the Antarctic Divergence. From February to April, in open areas of the Southern Ocean, a general Cchs decrease was observed. A similar trend was also noted in near-shore seas of the East Antarctic. At the shelf of the Sea of Cosmonauts, within the upper mixed layer, the content of chlorophyll amounted to 0.34-0.37 mg/m**3 . In the area of the continental slope, we registered formation of a subsurface chlorophyll maximum (0.52-0.56 mg/m**3) at 20 m depth, which deepened to 70 m when passing to the deepwater area. The positive correlation with a high coefficient (r = 0.939) between the field and satellite data (Cchs and Csat, respectively) allows one to conclude about ... : Supplement to: Demidov, A B; Vedernikov, Vladimir I; Sheberstov, S V (2007): Spatiotemporal variability of chlorophyll a in the Atlantic and Indian sectors of the Southern Ocean during February-April of 2000 according to satellite and expeditionary data.
