Ocean Currents

Front

What are ocean currents?

Back

Ocean currents are large-scale movements of seawater that flow through the world's oceans, driven by factors such as wind, water density differences, and the Earth's rotation.

What causes an increase in water density in the ocean?

Back

An increase in water density can occur when warm water loses energy and cools, or when salt is added to the water, making it heavier.

Front

What is upwelling?

Back

Upwelling is the process where deep, cold, nutrient-rich water rises to the surface, supporting the growth of marine producers like phytoplankton.

Front

What is the Coriolis Effect?

Back

The Coriolis Effect is the deflection of moving objects, such as air and water, due to the Earth's rotation, causing currents to curve to the right in the Northern Hemisphere and to the left in the Southern Hemisphere.

Front

What are surface currents?

Back

Surface currents are ocean currents that occur in the upper layer of the ocean, primarily driven by wind and affecting the climate and weather patterns.

Front

What are deep ocean currents?

Back

Deep ocean currents are movements of water that occur below the surface, driven by differences in temperature and salinity, and play a crucial role in global climate.

Front

What is the East Australian Current?

Back

The East Australian Current is a warm ocean current that flows southward along the eastern coast of Australia, famously featured in the movie 'Finding Nemo'.

Front

What is convection current in the ocean?

Back

Convection currents in the ocean are movements caused by the heating and cooling of water, where warm water rises and cooler water sinks, creating a cycle.

Front

How do ocean currents affect marine life?

Back

Ocean currents transport nutrients and organisms, influencing the distribution and abundance of marine life, particularly in areas of upwelling.

Front

What is the Gulf Stream?

Back

The Gulf Stream is a powerful warm ocean current that originates in the Gulf of Mexico and flows up the eastern coast of the United States, significantly affecting the climate of the region.
