Ocean currents can be generated by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes. Currents are cohesive streams of seawater that circulate through the ocean.
1 Temperature and density of ocean water are related inversely: warm water means low density, cold water means denser seawater. 2  The salt content of the water also affects Ocean density. 3  Sea Surface Salinity: Sea water is about a 3.49% salt solution, the rest is freshwater.4  The more saline, the denser the seawater. Pacific deep water is derived from the lower salinity water column of the southern ocean. 2  Towards the sea floor, temperatures are near 0Â°C marking the presence of Antarctic Bottom Water (AABW) derived from the very cold (-1.9Â°C; 34.65), dense water along the shores of Antarctica.
