作者在1985、1986和1987年对南沙海域3个航次的综合调查中发现,20—75m水层中普遍存在着O_2垂直分布中的最大值,最大值的位置在温跃层的下界附近,在叶绿素最大值和光束衰减系数最大值的上方,O_2最大值处同时出现P_(CO_2)最小值及pH最大值,这些现象用已有的关于中高纬度海区海水中O_2垂直分布最大值的理论似难以进行确切的解释。 本文阐明了我国低纬度海区海水中O_2垂直分布最大值是由于内波维持了涡动混合,形成了适合生物生长的环境及生物的成层分布,基于光合作用的结果加上温跃层的阻碍作用而形成O_2最大值。
In a comprehensive survey of 3 voyages in the Nansha sea area in 1985, 1986 and 1987, the author found that the maximum value of the O_2 vertical distribution prevails in the 20-75m water layer, with the maximum located near the lower bound of the thermocline, Chlorophyll maximum value and beam attenuation coefficient above the maximum O_2 at the same time P_ (CO_2) minimum and maximum pH value of these phenomena with the sea level in the mid-high sea O_2 vertical distribution of the maximum theoretical Difficult to explain exactly. This paper illustrates that the maximum vertical distribution of O_2 in seawater at low latitudes in our country is due to the eddy mixing maintained by the internal waves and the formation of a layered distribution of environments and organisms suitable for biological growth. Based on the results of photosynthesis and the hindrance of the thermocline The role of the formation of O2 maximum.
