Critical Zone Observatory

The Critical Zone Observatory (CZO) is a research network that studies the Earth's outer layer where the land, water, air, and living things interact. This zone extends from the top of the soil down to the bedrock and is vital for supporting life, regulating climate, and providing resources like water and nutrients. CZOs collect long-term data to understand processes such as erosion, weathering, and ecosystem changes, helping us anticipate environmental challenges and manage natural resources more sustainably. They are crucial for advancing our knowledge of how the Earth's surface functions and responds to natural and human influences.
