IMPACT OF ENVIRONMENTAL FACTORS ON INTERANNUAL DYNAMICS OF ORGANIC CARBON CONTENT IN SEDIMENTS OF THE NORTHERN CASPIAN
Journal Title: Вестник Астраханского государственного технического университета. Серия: Рыбное хозяйство - Year 2013, Vol 0, Issue 2
Abstract
The orientation of long-term dynamics of organic carbon content in sediments of different zones of the Northern Caspian is irregular and depends on sediments source of nourishment with organic matter. The organic carbon content in subsoil of the shoal water zone of the Eastern part of the Volga Delta pre-estuarine stretch and midstream sandbank Smirnovskiy depends on the organic flow rate and suspended material flow rate. It means that these areas are allochonous organic materials nourishment of sediments. Abyssal sea (steep-bottom) sediments have autochtonous organic nourishment, that is confirmed by dependence of the organic carbon content on the rate of production intensity (transparency, oxygen, pH).
