CIRCUMPOLAR DEEP WATER: SIMPLE FACTS



What is Circumpolar Deep Water?

It’s a warm and salty water current that flows deep in the ocean around Antarctica. It comes from the mixing of ocean waters from around the world.

Why is it important?

This water is warm enough to melt Antarctica’s ice from underneath, which can affect sea levels and climate.

How does it affect Antarctic ice?

The warmth of this water melts the ice from below, which can lead to ice breaking off into the sea.

What causes changes in how this water flows?

Wind, sea ice, and climate changes can change how this warm water reaches and affects the Antarctic ice.

Does it influence the global climate?

Yes, it helps move heat and nutrients around the world’s oceans, impacting the global climate.

Can it change sea levels?

Yes, by melting ice shelves, it can lead to more ice flowing into the ocean, raising sea levels.

Is the water always the same temperature?

No, its temperature can vary based on where it comes from and how it mixes with other waters.

Circumpolar Deep Water is key to understanding how Antarctica’s ice melts and how our global climate works.
