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.

赤道东大西洋表层的悬浮物质分布

摘要—该研究致力于悬浮颗粒物（SPM）的分布以及所谓的几内亚穹顶海洋上升流中的水文-水化学条件。该穹顶是直径为500 km的稳定旋风涡流，其中心位于北纬10°和北纬22°。它是由于赤道逆流活动的北部分支而形成的。2016年11月的一次航行使观察到圆顶北部高达50 m的等温线和等盐线的上升，以及在南部以南海面的高SPM浓度（高达0.7 mg / L）成为可能。 8°N。
