Asked by: Jon Franklin
Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation. The five major circulation patterns formed by the currents on this map are the world’s five major ocean gyres: North Atlantic, South Atlantic, Indian, North Pacific, and South Pacific.
What are the 5 major gyres?
There are five gyres to be exact—the North Atlantic Gyre, the South Atlantic Gyre, the North Pacific Gyre, the South Pacific Gyre, and the Indian Ocean Gyre—that have a significant impact on the ocean. The big five help drive the so-called oceanic conveyor belt that helps circulate ocean waters around the globe.

What is the largest gyre in the world?
The Great Pacific Garbage Patch is the largest accumulation of ocean plastic in the world and is located between Hawaii and California. Scientists of The Ocean Cleanup have conducted the most extensive analysis ever of this area.
Where are all the gyres?
Taken together, these larger and more permanent currents make up the systems of currents known as gyres. There are five major gyres: the North and South Pacific Subtropical Gyres, the North and South Atlantic Subtropical Gyres, and the Indian Ocean Subtropical Gyre.
What are the major surface currents?
Surface currents vary considerably in strength, width, temperature and depth. The five most notable gyres are as follows: Indian Ocean Gyre, North Atlantic Gyre, North Pacific Gyre, South Atlantic Gyre, and South Pacific Gyre.
What are the major ocean gyres and their importance?
Ocean gyres are large system of circular ocean currents formed by global wind patterns and forces created by Earth’s rotation.

How many gyres are in the Northern Hemisphere?
In the Northern Hemisphere the gyres rotate to the right (clockwise), while in the Southern Hemisphere the gyres rotate to the left (counterclockwise). There are five major gyres in the oceans; the North Atlantic, South Atlantic, North Pacific, South Pacific, and Indian (Figure 9.1. 2).
What is a gyre quizlet?
Gyre. Large circular moving loops of water that are driven by the major wind belts of the world.
How big is the South Pacific Gyre?
It stretched about 2,600 kilometers (1,600 miles) west to Easter Island. Altogether, it covers an estimated 3 million square kilometers (1.9 million square miles) of the ocean. That’s bigger than the country of India.
How big is the South Atlantic gyre?
Southern boundary
Another name for this current is the West Wind Drift. This current allows Antarctica to maintain its huge ice sheet by keeping warm ocean waters away. At approximately 125 Sv, this current is the largest ocean current.
How big is the North Atlantic gyre?
Based on a 22-year research study conducted by the Sea Education Association, the patch is estimated to be hundreds of kilometers across in size, with a density of more than 200,000 pieces of debris per square kilometer.
What is Majid gyre?
The Indian Ocean consists of one gyre, the Indian Ocean (Majid) Gyre, which exists mostly in the Southern Hemisphere. It is named after Ahmad Bin Majid, the 15th-century Arab mariner.
