Supply of Inorganic Carbon to Bottom Sediments of the North-Eastern Shelf of the Black Sea

The calculations of the possible supply of carbonate matter from the dominant mollusk species per square meter of shelf seabed were performed. Small-sized bivalves with short life cycles have been shown to contribute more to specific carbonate input to sediments than long-lived large-sized species, but less to absolute carbonate input. The model is proposed for calculating inorganic carbon input by molluscs of the north-eastern Black Sea coast based on single survey data with correction based on long-term monitoring results.
