in coastal regions. However, gyres DO NOT redistribute nutrients from the deep ocean.

What is the impact of gyres?

These gyres move warm waters from the south towards the north and in addition, they move cool waters from the north towards the south. Each gyre has a major effect on ocean circulation in that part of the ocean basin.

How do gyres affect ecosystems?

Gyres are an essential part of the Earth's ecosystem. These currents ensure nutrients and salinity are kept moving equally throughout the oceans. Nutrient distribution is important to feeding the ocean's teeming masses of life.
