海洋吸收了到达地球表面太阳幅射能量的约三分之二。太阳幅射加热了海洋,推动了海水的运动,影响着海洋与大气间的能量、质量交换。依赖太阳幅射进行光合作用的浮游藻类是海洋生产力的基础。光在海水中的传播、吸收、散射过程与水中的悬浮体和溶解物质有密切关系,也与海水的温盐度、流速等有关。海水的这些光学性质,表征出不同水团的某些固 The oceans have absorbed about two-thirds of the solar radiation reaching the Earth’s surface. The solar radiation heats the oceans and promotes the movement of sea water, affecting the energy and mass exchange between the sea and the atmosphere. Phytoplankton, which relies on solar radiation for photosynthesis, is the basis of marine productivity. Light in the sea water in the transmission, absorption, scattering process and water suspended solids and dissolved substances are closely related, but also with the sea temperature and salinity, flow rate and so on. These optical properties of seawater characterize certain solids of different water masses
