Abstract

Abstract

A study about biogenic elements on vertical transition profile in wInter and summer and data of time series sediment trap in the north of the South China Sea shows that particulate matter in that place mainly comprises biogenic carbonate,biogenic silica,organic matter and lithogenic matter,particulate matterflux is about 90.0 mg/(m²·d) at 1 000 m.The study also reveals most particulate organic carbon is dissolved before being buried in sediments,so organic carbon in sediments mainly comefrom lateral transition and contribution of vertical transition is limited.Comparing with open ocean of the East Pacific Ocean,the margin sea is more sensitive to the variety of season,furthermore,the investigated place of the East Pacific Ocean is located in the tropic equator with high production,obvioUs biologic effect makes biologic respiration and substantial transfer activ likewise.
