Stage 10 of the integrated coastal-marine scientific expedition "Black Sea - 2021"
The aim of this stage of the expedition (27.09 – 03.10) was to study the spatial distribution of anthropogenic pollutants in dissolved and suspended form in the upper quasi-homogeneous layer (UML) of the Black Sea, in the area of Gelendzhik.
The main tasks were:
- identification of background values of concentrations and composition of organic matter (OM) of natural and anthropogenic origin, different from plastic debris suspended in the surface layer or floating on the sea surface;
- study of the spatial distribution of OM in Gelendzhik Bay for anthropogenic pollution, assessment of its composition and probable sources;
- mapping of the spatial distribution of OM, phytoplankton chlorophyll and mineral suspension with high spatial and temporal resolution;
- carrying out quantitative assessments of the content of plastic waste in the surface layer of the sea and on the coast, studying its micro-growth;
- carrying out field experiments with samples of garbage thrown out by the sea selected on the coast for further verification of the method of its non-contact remote detection with a fluorescent lidar;
The expedition was attended by employees of our laboratory: V.V. Pelevin (head of the expedition), B.V. Konovalov, A.B. Grabowski
