Organic Matter Content Variations in Estuaries of Rivers and in the Barrier Zone of the Taganrog Gulf under the Impact of Climate Changes in the Northern Catchment of the Sea of Azov

摘要

Presented is a description of the river flow and content of hardly (humic substances) and easily (the final product is methane) oxidizable organic matter in it in the water of lower reaches of the Don, Severskii Donets, and Mius rivers in 1995-2009. Considered are the climate change effects in the river catchment on the content of dissolved organic matter in the river flow of estuaries and the change in species composition and volumes of primary production in the coastal waters of seas in arid zones. The present paper is a part of the theoretical basis considering the "climate-land-water" relationships for the further development of practical techniques in the field of ecology.
