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.
The difference in density of cold water versus density of warmer water is responsible for ocean currents and upwelling. Warm seawater floats and cold (4Â°C), dense (1 g/cm3), seawater sinks, so ocean temperatures also vary across the surface and into the depths.he Ocean and Temperature. Temperature and density share an inverse relationship. As temperature increases, the space between water molecules increasesâalso known as density, which therefore decreases. If the temperature of water decreases its density increases, but only to a point.
