Total suspended matter in the Gdansk deep at oxygenated / anoxic conditions in 2018—2023
... area cannot be considered a simple carbon sink. Intermediate nepheloid layers form during the seasonal shift from oxygenated to anoxic conditions, especially when local maxima of dissolved hydrogen sulfide detach from the seabed. The concentration of dissolved oxygen in the water varies significantly depending on the season, both in the surface and bottom layers, reaching its peak in winter and spring and its minimum in summer and autumn.
