Abstract

Abstract

Organic carbon and neutral monosaccharides were performed on sediments from Prydz Bay (Antarctic) during the CHINARE-18/21 cruise.The results show that the distributions of organic carbon and neutral monosaccharides in surface sediments were controlled by primary production in upper water, submarine topography and water stability.The average cotent of neutral monosaccharides in surface sediment is 3.03 mg/g, the hig hest value is 5.60 mg/g and occurred in adjacent continental shelf.The relation between concentration of organic carbon and Chl a in surface water is close.The neutral monosaccharides compositions can reflect the source of biogenic matter.Plankton in upper ocean are the main source of organic carbon in surface sediment.The neutral monosaccharides are liable to degrade.We can presume the relative sedimentation rate by the abundance of hexoses and their vertical distributions.
