Chlorophyll a and primary production in the Chinese Contract Area in the east-north Pacific

Third Oceanography Institute, State Oceanic Administration Xiamen 361005, China

摘要

摘要: 根据东北太平洋中国合同区东区和西区从1994年至2003年6个航次(DY85-4,DY95-7,DY95-8,DY95-10,DY105-11和DY105-12.14)初级生产力调查资料编写.结果表明:次表层高值分布为叶绿素a分布的一般特征,从表层至水深50 m,数值为0.1 mg/m³左右,在水深50~100 m上下,数值约在0.2~0.4 mg/m³之间,在水深大于100 m,特别是150 m以深数值逐渐减小为零;东区初级生产力(C)测值在76.8~191.9 mg/(m²·d),平均为116.1 mg/(m²·d);西区的在73.1~222.5 mg/(m²·d),平均为127.1 mg/(m²·d);在水深0~125 m,0.2~2μm颗粒的微微型浮游植物的叶绿素a比例占叶绿素a总量的70%以上,而在水深125 m以深,占50%以下;反之,2~20μm和大于20μm两种粒级所占比例的和在0~125 m深度范围占30%以下,在水深125m以深时为50%以上.调查显示东、西两区属于初级生产力比较低的海域.

Abstract: It was for med based on the data obtained from the east and west regions of Chinese Contract Area in the NE of Pacific Ocean during 6 surveys, DY85-4, DY95-7, DY95-8, DY95-10, DY105-11 and DY105-12.14, in years from 1994 to 2003.The result shows that the maximum chlorophylla distribution was located under the subsurface water layer, following the general distribution pattern for Chlorophylla.It was measured that the chlorophylla around 0.1 mg/m³ was found from the surface water to 50 m depth and around 0.2~0.4 mg/m³ was from 50 to 100 m.It diminished below 100m depth and zeroed particularly at 150 m depth.The primary production(C) in range from 76.8~191.9 mg/(m²·d) with average 116.1 mg/(m²·d) was located in the east region, and the production from 73.1 to 222.5 mg/(m²·d) with average 127.1 mg/(m²·d) was in the west region.The picoplanktonic chlorophyll a in particle size from 0.2 to 2μm was accounted for more than 70% of the total and it decreased to less than 50% in depth below 125 m.The particles with size from 2 to 20μm and over 20μm were only accounted for less than 30% of the total at depth from 0 to 125 m while it rose above 50% below 125 m depth.It demonstrated that the primary production in both regions should be classified as the areas of lower productivity.
