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. NSF CZO scientists study how the critical zone responds to changes in climate and land use. At the 2017 AGU Fall Meeting, held at the New Orleans Ernest N. Morial Convention Center in New Orleans, Louisiana, from Dec. 11-15, 2017, 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. CZO scientists will discuss plants as plumbers and builders of the critical zone; the effects of Hurricane Maria on the Luquillo, Puerto Rico, critical zone; wildfire in the critical zone; rainfall-triggered landslide hazards; carbon dioxide in sagebrush steppe ecosystems; land-use legacies of old-field succession; snow-dominated headwater catchments; and myriad other subjects. Researchers at NSF's CZOs are working to answer such questions as:
The NSF CZO program will host booth #2032 in the exhibit hall. On Thursday, Dec. 14, the program will host a town hall meeting, "Critical Zone Observatories: Platforms for Collaborative Science," from 12:30-13:30 in the New Orleans Ernest N. Morial Convention Center, rooms 208-209. Find a partial list of CZO science-related sessions, talks and posters by date/time below.
