Transcript of Ocean Currents

Ocean Currents

presented by: Nelson Barahona, Alejandra Fajardo, Mariana Godoy and Mylka Puerto

What are ocean currents?

How are ocean currents formed?
What is their importance?
They are a large volume of water flowing in a certain direction.
They can be warm or cold currents.

Surface currents are formed by wind patterns, these patterns are determined by wind direction, Coriolis forces from Earth's rotations and the position of landforms that interact
They may also be caused by density differences in water masses caused by temperature and salinity variations.
Factors
What do they affect?
Since ocean currents circulate water worldwide,they have a big impact on the movement of energy and moisture between the oceans and the atmosphere.
They also help in voyages like trade or movement of people.

Ocean currents affecting climate
Ocean's currents factors :
wind
density differences in water masses caused by the temperature and salinity
gravity
events like earthquakes
Gyres; these are spiraling circulations lying on a current, they are the dominant pattern of surface circulation
The great ocean conveyor belt: is a constantly moving system of deep-ocean circulation driven by temperature and salinity.



The ocean currents affect the climate. Regions near warm-water currents are often warmer and wetter than regions near cold-water currents.

Fun Facts
Some marine animals take advantage of the currents and migrate thousand of miles.
It takes a minimum of 500 years and up to a 1,000 years for the oceans' water to cycle itself globally.
The Gulf Stream carries almost 100 times the volume of all the world's rivers.
Japan's Kuroshio is equal in voulume to 600 large rivers.
