Scientific Head: Maiorova A.S., senior researcher, Cand. Sci. Biol.
Main fields of research:
- Spatial structure, monitoring and evaluation of bioresource potential of bottom communities using ROV surveying;
- Trophic relationships in aquatic ecosystems and their dependence on production parameters of the environment;
- Development of methods and technologies for cultivation of marine organisms under natural and artificial conditions;
- Effect of plastic particle (micro- and nanoplastics) pollution of aquatic ecosystems on physiological and biochemical functions of aquatic organisms;
- Patterns of periphyton communities dynamics and development of methods of fouling control;
- Geochemical cycles of nutrients in bottom sediments of marine ecosystems.
Approaches and methods used
- Laboratory and in situ experimental research methods;
- Non-contact methods of studying bottom communities structure and point sampling with ROVs;
- Sample collection using traditional hydrobiological gear and modern tools: plankton nets, trawls, dredges, bottle samplers, bottom grabs, box-corers, multicorers, sediment tubes, bottom sledges;
- Instrumental (CTD profiler) and hydrochemical methods for studying aquatic environment parameters;
- Mass spectrometry (stable isotopes distribution);
- Microscopic and histological methods of taxonomic research;
- Chromatographic methods for studying biogeochemical processes in bottom sediments.
Range of organisms and objects under study
- Echinoderms, polychaetes, sponges, echiurans, bivalves, crustaceans;
- Hydrochemical parameters of water and bottom sediments as a habitat;
