Abstract
Results of field bio-optical studies carried out in the South Atlantic (Falkland (Malvinas) Current) and in the northern part of the Antarctic Peninsula (Bransfield Strait and Antarctic Sound) are presented. It was found that bio-optical parameters in the main stream of the Falkland (Malvinas) Current are lower than in the surrounding waters. Upwelling was observed in the western periphery of the current, which contributes to the ascent of nutrients to the surface. Thus, intense development of phytoplankton exists in the surface layer, which is the main component in the suspended matter composition. A high correlation between remote sensing and field data was revealed in this region. Based on the results of research in the Bransfield Strait, the presence of two streams with different hydrological and bio-optical characteristics was found. Waters rich in nutrients were found in the northeastern part of the strait along the South Shetland Islands. Less productive waters from the Powell Basin were revealed in the eastern part of the strait. No influence of the alongshore current from the Drake Passage on bio-optical structure was observed at depths exceeding 100 m in the Bransfield Strait. The Antarctic Sound was characterized by the presence of clearer water. Only in the 50 m surface layer, were areas with different hydrological and bio-optical characteristics from the main water mass. Presumably, such a pattern of the subsurface layer was associated with the inflow of more turbid waters from the Bransfield Strait, caused by wind forcing.
