- Definition any current in either a liquid or a gas that is kept in motion by the force of gravity acting on small differences in density Reference "Encyclopaedia Brittannica > Science and Technology > density current. http://www.britannica.com/EBchecked/topic/157980/density-current [31.8.2010]"
- Comment "A density difference can exist between two fluids or between different parts of the same fluid because of a difference in temperature, salinity, or concentration of suspended sediment. Density currents in nature are exemplified by those currents that flow along the bottom of oceans or lakes. Such subaqueous currents occur because the water entering an ocean or a lake is colder, saltier, or contains more suspended sediment and, thus, is denser than the surrounding waters. As a consequence, it sinks and flows along the bottom under the effect of gravity. The difference in density, moreover, slows down the mixing of the subaqueous current with the overlying waters, enabling it to maintain itself for a relatively long distance.Note ref.: Encyclopaedia Brittannica > Science and Technology > density current. http://www.britannica.com/EBchecked/topic/157980/density-current [31.8.2010]"
