Ocean Currents

Salinity

• A directional movement of ocean water; surface currents result from steady winds over the ocean surface; deep currents result from density variations due to temperature and salinity differences.

• A large body of saltwater that covers most of Earth’s surface

• Saltiness or dissolved salt content of a body of water

• The value for water at 0°C and standard sea-level atmospheric pressure is 1g/cm3.
