摘要

摘要: 通过对南海北部夏、冬两个季节的生源要素垂直输运剖面和时间系列沉积物捕获器的测量资料进行综合研究表明:南海北部颗粒物质主要是由钙质生物壳、生物硅、海洋浮游生物的有机质以及岩源物质组成,颗粒物质通量在1 000 m处大约为90.0 mg/(m²·d);研究还表明颗粒有机碳在进入沉积物保存之前被大量溶解,南海北部来自底层顺坡搬运的有机碳远大于垂直沉降;与开阔大洋(东太平洋海域)的对比研究表明,边缘海对于季节的变化更加敏感,而东太平洋调查区位于热带赤道高生产力带,生物作用十分明显,其海洋生物呼吸和物质转移同样也较活跃.

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.
