Simulation of the impact of internal waves on the oxygen/hydrogen sulphide co-existence zone in the open part of the Black Sea

This paper focuses on the impact of periodic internal waves on the oxygen/hydrogen sulphide co-existence zone in the open Black Sea. The numerical model is based on a set of transport/diffusion equations governing the evolution of oxygen/hydrogen sulphide concentrations and considering the reaction between them. The wave velocity field is determined by solving a spectrum problem for preinertial period internal waves, using the characteristic vertical density profile for summertime. Via analysis of the model data, the influence of wave characteristics on the parameters of the O₂/H₂S co-existence zone has been assessed.Translated by Vladimir A. Puchkin.
