Topics range from the function of Earth's 'living skin' to interactions between climate and bedrock

The thin veneer of Earth's surface that stretches from the top of the forest canopy to the base of bedrock is known as the "critical zone." It's where fresh water flows, rock turns to soil, and life flourishes.
To provide a deeper understanding of the critical zone, the National Science Foundation (NSF) supports nine Critical Zone Observatories (CZOs) that stretch from coast to coast. CZO scientists study how the critical zone responds to changes in climate and land use.
At the upcoming American Geophysical Union (AGU) fall meeting, Dec. 12-16, dozens of CZO researchers will present new results on a range of topics, from the structure, function and evolution of Earth's "living skin" to the interactions between climate and rocks.
Researchers at NSF's CZOs are working to answer such questions as:
- How do landscapes evolve over human timescales and over millennia, and how is that process affected by the presence and flow of water?
- How do soil and weathered bedrock move down hillslopes, and how are they linked with the evolution of channels that often surround the bases of these hillslopes?
- How do biological processes affect physical processes such as erosion and weathering?
- Are there signals in the landscape that can tell us about past climates and about how landscapes responded then, or might respond in the future, to climate change?
Below is a list of selected CZO talks, posters and events at the AGU meeting, which will take place in San Francisco. For more on NSF's CZOs, please see: Critical Zone Observatory Network and NSF CZO Discovery Article Series.

The National Science Foundation (NSF) is an independent federal agency that supports fundamental research and education across all fields of science and engineering. In fiscal year (FY) 2016, its budget is $7.5 billion. NSF funds reach all 50 states through grants to nearly 2,000 colleges, universities and other institutions. Each year, NSF receives more than 48,000 competitive proposals for funding and makes about 12,000 new funding awards. NSF also awards about $626 million in professional and service contracts yearly.
