The ocean surface rapidly exchanges heat, freshwater, and gases with the atmosphere, but once water sinks into the ocean interior, the inherited properties of seawater are closely conserved. Previous water-mass decompositions have described the oceanic interior as being filled by just a few different...
Lake Baikal is the biggest body of fresh water on Earth It's about 1. 6 km in depth and is also thedeepest. Several unusual anumals call t home, including the world's only species of freshwater seal. There area large number of Baukal seals, about 8,000 -10,000. But the lake is...
Freshwater: Freshwater is the kind of water terrestrial plants and animals need to survive. It has less than 1,000 parts per million (ppm) of salt in it. So freshwater does not mean it has no salt but it has a very low level of salt in the water. ...

The ocean circulation is forced at large scales by boundary fluxes of momentum, heat and freshwater as well as by the astronomical tidal potential. The variability of these forcings provide energy to the ocean, whose motions span a wide range of spatial and temporal scales. Yet, climate equilib...
