普里兹湾及其毗邻海域溶解氧最大值

The maximum value of O_2 in the Prize Bay and its adjacent sea area

作者在１９９０～１９９３年的夏季（１～２月）对南极普里兹湾海域４个航次的综合调查中发现，２５～５０ｍ层中普遍存在着溶解氧垂直分布最大值，其位置在温跃层的下界附近，而温跃层强度分布趋势与溶解氧最大值趋势相类似。作者认为温、密跃层的强弱是产生溶解氧最大值的先决条件。海冰冰况的时空变化是影响溶解氧表层量值的重要因素。

During the period from summer of 1990 to summer of 1993, the maximum value of O2 vertical distribution was widespread discovered in the water depth of 25 to 50 m in the sea area ofthe Prize Bay,Antarctica.The value occurred in the bottom of the thermocline. and thedistribution trend of the thermocline strength is similar to that of the maximum value of O2. Theauthor consider that the strength of both thermocline and density transition layer is the condition ofproduction of the maximum value of O2.The changes of time and space of sea ice is the importantfactor influencing the surface value of O2.
