On October 17, 2022, the 52nd voyage of the RV Akademik Boris Petrov began, with a duration of 75 days. Research area: western tropical Atlantic. The head of the expedition is DSc E.G. Morozov.

The purpose of the expedition: to study deep currents in the abyssal depths of the Atlantic, the processes of interaction between the ocean and continental runoff and anthropogenic pollution of the marine environment in the zone of influence of the Amazon River, as well as the development of international scientific cooperation between the BRICS countries.

The expedition program includes the study of the flow of Antarctic bottom water in the faults of the North Atlantic Ridge. The main fault through which the flow of Antarctic bottom water flows is the Vema fault at 11°N. It is planned to study the plume of the removal of fresh water from the Amazon and anthropogenic pollution of the marine environment in the area of the plume. The work will be carried out jointly with scientists from Brazil.
