摘要：

本文讨论了南极南设得兰群岛及阿得雷德岛以北海域夏季氧最小层分布及其控制因。计算了氧最小层处氧含量同所在温度、盐度、密度、pH和表观耗氧量(AOU)之间的相关系数,并讨论了它们之间的相关性。氧含量同温度和AOU呈密切负相关(相关系数r分别为-0.9688和-0.9945),这表明氧最小层氧含量变化主要受深层水团温度和生物化学过程控制。

Abstract:

In this paper the distribution of oxygen-minimum layer and factors controlling on it in the sea areas adjacent to South Shetlands and north of Adelaid, Antarctica, in summer is discussed.The correlation coefficient between oxygen content, temperature, salinity, density, pH and apparent oxygen utilization (A.O.U.) in the oxygen-minimum layer is calculated and correlation between them is discussed. The correlation between oxygen, temperatur and A.O.U are negative (r= -0.9688, -0.9945, respectively) .The variation of oxygen-minimum layer is mainly controlled by temperature and biochemical process in deep water.
