Natural abundance of ~(15)N in suspended particulateorganic matter from Prydz Bay, Antarctic
本文研究了南极普里兹湾海域悬浮颗粒物中的天然15N丰度,并就δ15N与POC、PON等生化要素之间的相关性进行了讨论,对δ15N含量分布特征的形成机制及其与物理、生物学过程的耦合进行了探讨,给出了南极普里兹湾悬浮颗粒物中的δ15N与POC、PON含量呈负相关关系;表层水中δ15N、POC和PON的分布和δ15N的垂直分布可能与涡流有关. 【英文摘要】 The space distribution of natural abundance of ()~(15)N in suspended particulate organic material (POM) was determined with POC and PON. The relationship of ()~(15)N versus POC and PON respectively and the distribution mechanism formed and coupled with physical and biological process were discussed. It showed that ()~(15)N and POC and PON are positively correlated. The vertical distribution of ()~(15)N and distribution of ()~(15)N POC and PON in surface water may deal with eddy.
