density current

Show Summary Details

Quick Reference

A current that is produced by differences in density. Where a flow of sea water has a greater density than that of the water surrounding it, the denser water will dive beneath the less dense water. The density of sea water is affected by temperature, salinity, and the content of suspended sediment. Most deep and bottom ocean currents are density currents. See also turbidity current.
