Please consider submitting an abstract to one of these two sessions at the AGU Fall Meeting. The abstract deadline is August 1. Submit here: https://fallmeeting.agu.org/2018/abstract-submissions/.
Session Description: The thin skin of the Earth stretching from the outer canopy of vegetation to groundwater nourishes human civilization. At the same time, this thin skin evolves over timescales ranging from geological to climate change to human timescales, through processes that shape landscapes, form soils, and control water. Critical zone science has nucleated as a central focus of environmental earth scientists worldwide who recognize that this thin skin must be studied in its entirety instead of in separate parts. This new worldview of integrated study of the critical zone is now impacting societal perspectives, policy decisions and stewardship paradigms of our environment. Presentations in this session will highlight advances in all of these dimensions, while emphasizing the necessity to look at the critical zone as one unit.

Session Description: Integrated monitoring and experimentation in field observatories have played a critical role in developing ideas about soil function, hydrologic processes and ecological systems. In this session we highlight contributions from soil observatories (e.g., Rothamsted, Calhoun), the USGS Hydrologic Benchmark Network (HBN) and Water, Energy, and Biogeochemical Budgets (WEBB) network, experimental forests, NSF-funded field observatories (e.g., LTER sites, CZOs, NEON), and other observatories world wide. Deeply integrated measurements and long-term observations in a fixed location yield insights that often could not have been predicted at the outset. Long-term soil study at Rothamsted connects soil nutrient status to human health. The USGS HBN and WEBB networks reveal long-term trends in stream flow and water quality that can be used to discern effects of changing climate and atmospheric deposition. This session welcomes contributions from observatories, particularly where the observatory approach yielded unexpected insights.
