Abstract—The research is dedicated to the suspended particulate matter (SPM) distribution and the hydrological–hydrochemical conditions within the oceanic upwelling of the so-called Guinea Dome. This dome is a 500 km diameter stable cyclonic eddy, the center of which is located at 10° N and 22° W. It was formed owing to northern branch of Equatorial Counter Current activity. A cruise in November 2016 made it possible to observe the rising of isotherms and isohalines up to 50 m in the northern part of the dome, as well as a high SPM concentration (up to 0.7 mg/L) in the ocean surface layer south of 8° N.
