The fall edition of CZNews, the CZO National Office newsletter, is now available at The newsletter features new CZO Program Director Richard Yuretich, CZO partipation at the LTER triennial meeting, results from a workshop on the deep Critical Zone, and more! 

Bruno Latour Tours Calhoun CZO

Prof. Bruno Latour is very excited by his visits to the US CZOs, first So. Sierra and Eel River during the summer of 2015 and most recently the Calhoun CZO, 21-24 Sept.  His 4-p paper at Jerome's Geochemistry meeting (Sept 2014) is still a landmark of creativity with regards the richness and broad importance of cz science.

B052: Multi-Scale and Integrated Sensing for Watershed Science

American Geophysical Union -- Session ID# 8983 Description: Gaining a predictive understanding of dynamic ecosystem and hydrological processes in watersheds involves complex surface and subsurface hydrology, biogeochemistry, and vegetation dynamics. Heterogeneous properties and responses are needed in sufficiently detailed spatial and temporal resolution. However, properties and responses must be averaged, translated, and/or upscaled to integrate over the entire watershed or watersheds. While there has been some progress towards developing multi-scale approaches to understand and predict watershed-scale behavior, the community still struggles to extrapolate knowledge beyond the point scale. However, advances in technology and interdisciplinary cooperation are changing this trend.

Public Consultation on International CZOs

Register your views on the draft science agenda and next steps for organizing international CZO research 

An international meeting of Critical Zone (CZ) researchers supported by the US NSF and the European Commission FP7 project SoilTrEC met at the University of Delaware during November 2011. The meeting summarised international advances in CZ science and took the initial steps towards forming an international Critical Zone Observatory (CZO) research programme and a 10-year CZ science agenda. The full report from that meeting has been published by the University of Sheffield, United Kingdom, and is now available for download. 

We invite public input on the 1-page outline plan for developing an international CZO research programme.

Thank you in advance for your participation in this consultation.
