What are Ocean Currents? | Every Full Moon | Ocean Today
This is ocean current. The reason we have currents in the ocean is a bit more complicated. Let's go back to the shoreline to witness one cause of ocean currents. Tides. 1. Tidal Currents. …
Currents: NOAA's National Ocean Service Education
A second factor that drives ocean currents is wind. Winds drive currents that are at or near the ocean's surface. These currents are generally measured in meters per second or in knots (1 …
What causes ocean currents? - National Oceanic and Atmospheric ...
Currents may also be caused by density differences in water masses due to temperature (thermo) and salinity (haline) variations via a process known as thermohaline circulation. These …
