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 density of surface seawater ranges from about 1020 to 1029 kg/m 3, depending on the temperature and salinity. At a temperature of 25 Â°C, salinity of 35 g/kg and 1 atm pressure, the density of seawater is 1023.6 kg/m 3. Deep in the ocean, under high pressure, seawater can reach a density of 1050 kg/m 3 or higher.
