盐跃层

北冰洋盐跃层研究进展

Advances in studies on the Arctic halocline

热带气旋过境后，温跃层与盐跃层的位置变深，层结强度减弱。

The depth of thermocline and halocline descended after the tropical cyclone-and their stratifications got weaker than before .

由于两季节层化程度的不同，营养盐跃层深度也不同，春季在30m以深，夏季为30m以浅。

The stratification depth in two seasons is different that which is below 30m in spring and above 30m in summer .

结果表明：溶解态无机氮、磷的浓度在锋面和盐跃层出现明显的跃变；

The concentrations of the dissolved inorganic nitrogen , phosphorus change abruptly at the plume front and halocline .

在海冰边缘区，冰下海洋的温度和盐度也有了独特的结构，特别是在15-40米深的海洋表层有次表层暖水和较弱的盐跃层的独特结构。

Especially , there have some special structures , which are subsurface warm water and weak vertical gradient in ocean salinity .

20世纪90年代，在北冰洋观测到一系列异常变化，包括盐跃层退缩、大西洋层增暖和北极海冰减少。

Since 1990s , a series of anomalous variations had been found , such as the retreating of CHL , the warming of the Atlantic layer and the decreasing of the Arctic sea ice .

通过建立垂向的一维对流-扩散模型，估算了温盐跃层以下水体（即黄海冷水团内部）由底部向上的垂直涡动扩散系数以及相应的营养盐输送通量。

Similarly , based on a vertical one-dimentional advection-diffusion model ( neglecting advection ), the vertical eddy diffusion coefficients below the thermocline ( within the Yellow Sea Cold Water Mass , YSCWM ) are estimated .

1987年7月粤东陆架区温、盐、密度跃层的分布特征

长江口及济州岛邻近海域温、盐、密度的跃层现象调查区内叶绿素a变化范围是0.2～18.7mg/m~3。在垂直分布上，叶绿素a同跃层密切相关，呈现出三种分布类型。
