What are the two types of ocean circulation?
Ocean circulation derives its energy at the sea surface from two sources that define two circulation types: (1) wind-driven circulation forced by wind stress on the sea surface, inducing a momentum exchange, and (2) thermohaline circulation driven by the variations in water density imposed at the sea surface by ….
What are the 4 types of ocean currents?
Ocean Currents and Climate. There are two type of Ocean Currents: … Solar Heating.Winds.Gravity.Coriolis. Secondary Forces–influence where the currents flow.Surface Circulation. Solar heating cause water to expand. … North Atlantic Gyre. Note how the North Atlantic Gyre is separated into four distinct. … Ekman Transport.More items…
What is the most powerful ocean current?
Antarctic Circumpolar CurrentThe Antarctic Circumpolar Current is the planet’s most powerful and arguably most important current. It is the only current to flow clear around the globe without being diverted by any landmass.
What happens if ocean currents stop?
If it continues to slow, that could have profound consequences for Earth’s inhabitants. Studies suggest it would mean much colder winters and hotter summers in Europe, changing rainfall patterns in the tropics, and warmer water building up along the U.S. coast that can fuel sea level rise and destructive storms.
What are the two main factors that affect deep ocean currents?
Winds, water density, and tides all drive ocean currents. Coastal and sea floor features influence their location, direction, and speed. Earth’s rotation results in the Coriolis effect which also influences ocean currents.
What causes ocean water to circulate?
Ocean currents can be caused by wind, density differences in water masses caused by temperature and salinity variations, gravity, and events such as earthquakes or storms. … These currents move water masses through the deep ocean—taking nutrients, oxygen, and heat with them.
How long does it take for ocean water to circulate?
1,000 yearsIt is estimated that it can take 1,000 years for a “parcel” of water to complete the journey along the global conveyor belt. Cold, salty, dense water sinks at the Earth’s northern polar region and heads south along the western Atlantic basin.
What is the current in the ocean called?
Deep ocean currents are driven by density and temperature gradients. This thermohaline circulation is also known as the ocean’s conveyor belt. These currents, sometimes called submarine rivers, flow deep below the surface of the ocean and are hidden from immediate detection.
What are the 5 major ocean currents?
There are five major gyres: the North Atlantic, the South Atlantic, the North Pacific, the South Pacific and the Indian Ocean Gyre, see figure 1. The Antarctic Circumpolar Current is situated in the Southern Ocean and constantly circles around Antarctica because there are no land masses to interrupt the currents.
