25 surface sediment samples were collected during the 2nd Chinese National Arctic Research Expedition(CHINARE)in summer,2003. Chlorin were analyzed by high-performance liquid chromatography(HPLC). Chlorin content ranged from 0.04μg/g to 125.29μg/g,with an average of 18.92μg/g. High chlorin value was observed at shelf area of Chukchi Sea,where marine environment were mainly controlled by nutrient rich Anadyr and Bering Sea shelf currents flowing through Bering strait, which promote the growth of phytoplankton and lead to increasing of the marine-derived organic material deposition. Chlorin content in sediment from Canada Basin were lowest because of low productivity in the water column and pigments degradation during the longer settling and sedimentation processes. The integrated Chlorophyll a in the water column showed that the higher contents was also observed at the shelf area,although there is an insignificant correlation between the chlorin and water column phytoplankton production. While, when Chorin content was normalized with organic carbon in the sediment, it came out a significant correlation between them, which means, that this index could provide important information for understanding long time scale variation of marine ecosystems in upper Arctic Ocean.
