胶州湾海水中颗粒有机碳含量的分布与变化

DISTRIBUTION AND VARIATION OF PARTICULATE ORGANIC CARBON CONTENTS IN THE SEAWATER OF JIAOZHOU BAY

本文报道了胶州湾表层海水及C_3和D_3站中层和底层水中的颗粒有机碳(POC)的分布与变化规律。结果表明,胶州湾POC年平均浓度为155～410μg/L;平面分布有明显的规律性,近岸和河口一带的含量较高,湾中部较低,湾口诸站为最低;垂直分布有个别数值偏高或偏低现象,但没有明显的规律;季节变化较明显,初春较高,秋季较低。

In this paper, the distribution and the seasonal variation of paniculate organic carbon (POC)contents in the surface seawater from 14 stations as well as distribution with depths at two stations (C3 arid D3) in Jiaozhou Bay during June-November 1981 and March-May 1982 were reported. The results showed that the average values of POC contents in surface seawater varied frqm 155 to 410μg/L, and the contents near the coast and estuary regions are higher (300 μg/L) than those far from them (180μg/L), the seasonal variation of the average values of POC contents in surface seawater of all stations was evident, which was higher in the early spring, (about 300 μg/L) and lower in the autumn, (about 190 μg/L) the vertical distribution of POC contents at three depths, surface, middle and bottom layers of two stations (C3 and D3) was unremarkable.
