- Abstract
In the fall of 2018, studies of suspended particulate matter and its organic part in the water column and their lateral flux on the Karelian coast of the White Sea were carried out. The concentration of suspended particulate matter varied from 0.42 to 0.93 μg/L, and the concentration of Corg ranged from 124 to 249 μg/L. In the water column, 25 registration taxa of phytoplankton were recorded; it was shown that its species composition changed from the surface to the bottom. The lateral flux values varied from 159 to 439 μg m–2 h–1. As part of lateral flux, 49 phytoplankton taxa were revealed. It was shown that, depending on the tidal cycle phase, not only the quantitative characteristics of the lateral flux of phytoplankton change, but also the species composition of microalgae. In the tidal phase, more organic matter enters the inner regions of the bays than is carried out from these areas to the low-tide phase. At high tide, the proportion of phytoplankton organisms in the lateral flux is more than 80%; at low tide, it is less than 55%.
