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.
Density of seawater is primarily determined by two factors: temperature and salinity. Warmer water is less dense than colder water. Therefore, warm water floats near the surface while cold water will sink toward the bottom. Salinity also affects density. Higher salinity (more salts in the water) leads to higher density. So salty water sinks while fresh water floats at the surface. Anywhere in the ocean where water masses of different salinity and/or different temperature meet, the ocean will be stratified.
