The paper presents an analysis of the spatial variability and vertical distribution of bio-optical parameters of seawater in the zone of interaction of the Falkland (Malvinas) Current with the waters of the Patagonian shelf. In addition, an assessment of the influence of the chlorophyll a maximum concentration depth on the satellite remote sensing reflectance is shown. Field data were obtained during the 79th cruise of the R/V Akademik Mstislav Keldysh on January 12 and 13, 2020. Underway flow-through measurements and stations were carried out across the Falkland Current (along 45.8S). Additionally, ocean color satellite data obtained with the MODIS-Terra and OLCI Sentinel-3B radiometers and oceanographic reanalysis data were used. It is shown that in the region of interaction of the Falkland Current with the Patagonian shelf, there is an alternation of zones of upwelling and downwelling, leading to a change in the chlorophyll a maximum concentration depth, which in turn can affect the variations in the satellite remote sensing reflectance. The upper layer depth, where the position of the chlorophyll a maximum had a significant effect on the shape of the spectrum and the values of the sea remote sensing reflectance, was estimated as 14 m.
Keywords: chlorophyll a, colored dissolved organic matter, bio-optical characteristics, sea color, sea brightness coefficients, vertical profile, hydro-optical modeling, satellite data, MODIS, OLCI, Hydrolight, Falkland Current, Patagonian shelf
