WebDec 14, 2014 · Changes in salinity impact sea level rise more than previously thought – oceanbites The main mechanisms driving sea level rise were thought to be through the melting of land-based ice (such as glaciers) and through the thermal expansion of sea water with increasing global temperature. Understanding why the sea is salty begins with knowing how water cycles among the ocean's physical states: liquid, vapor, and ice. As a liquid, water dissolves rocks and sediments and reacts with emissions from volcanoes and hydrothermal vents. This creates a complex solution of mineral salts in our ocean basins. … See more Surface winds drive currents in the upper ocean.
