现代亚北极太平洋中陡垂直盐度梯度（盐跃层）将表层水与下部富营养质水体相隔离 ,明显影响极地环境中的大洋上部层次。盐跃层物理作用过程 ,物理、生物和地球化学反应长期以来是人们十分关注的题目。极地表层水层次影响着大洋与大气之间的ＣＯ２交换 ,因此 ,亚北极太平洋温跃 The steep vertical salinity gradient in the modern sub-Arctic Pacific (salt layer) isolates the surface water from the lower eutrophic water and significantly affects the upper ocean level in the polar environment. The physical processes of salt thermodynamics, physical, biological and geochemical reactions have long been a subject of great concern. The polar surface water layer affects the CO2 exchange between the ocean and the atmosphere. Therefore, the sub-Arctic Pacific warm-winters
