海洋生物泵研究进展

Progress in oceanic biological pump

海洋生物泵是以一系列海洋生物为介质将大气中的碳输运到海洋深层的过程,是海洋碳循环的重要组成部分以及未来的研究重点。本文系统地描述了海洋生物泵碳汇几个主要阶段:浮游植物沉降,浮游动物粪球颗粒沉降,透明胞外聚合颗粒物(TEP)沉降和海雪沉降以及碳酸盐反向泵过程。同时,本文对南海生物泵的研究进展进行简要介绍,服务于中国海碳循环。

Oceanic biological pump,as an important component of oceanic carbon cycle,transfers the atmospheric carbon into the deep ocean.In this paper,the processes in oceanic carbon sink and biological pump are discussed,including sinking of phytoplankton cells,zooplankton fecal pellet package effects,transparent exopolymer particles（TEP）sinking,marine snow sinking and carbonate counter pump.Meanwhile,the present paper attempts to state the progress and perspectives of the biological pump in the South China Sea,which contributes to the carbon cycle in China Seas.
