Events 

• 2019 AGU International Critical Zone Network-of-Networks Early Career Workshop 
  Sunday, 8 December 2019
  
  Critical Zone Observatories (CZOs) are instrumented field sites for monitoring hydrological fluxes, energy matter, and biogeochemical cycles - from bedrock to canopy, across terrestrial and aquatic interfaces, and across climatic and hydrobiogeochemical gradients. Networks of CZOs and their Watershed equivalents have been established in many countries, including in the US, France, Germany, and Canada. Critical zones and watersheds are “human habitats”, important for sustaining basic human needs such as water, food, and energy as well as crucial for the ecosystem services they provide. The future behavior of these systems is uncertain due to changing environmental conditions as well as rapidly growing population, urbanization, industrialization and irrigation for food production. A systematic approach is needed to explore how critical zone networks are tackling the challenge of understanding and predicting their systems, including associated questions, tools and approaches.  This one day workshop presents such a platform to formally bring together an international cohort of early career scientists from across these CZO/Watershed networks to initiate this systematic approach.
   
• 5th Annual International CZO Workshop
  Sunday, 8 December 2019 
   
• Town Hall: The Critical Zone: Observatory Progress and New Opportunities
  Thursday, 12 December 2019 | 12:30 - 13:30 | Moscone West - 2003, L2
  
  Critical Zone Observatories (CZOs) are natural laboratories for investigating Earth surface processes. CZO research seeks to understand these coupled processes across all timescales using quantitative models parameterized from observations of meteorological variables, streams and groundwater, and sampling and analyzing landforms, bedrock, soils, and ecosystems. Teams of cross-disciplinary scientists at nine sites across the U.S. work to further CZ science using field and theoretical approaches, education and outreach. The U.S. network includes a national office that works with other U.S. entities including the LTER network and CUAHSI, and various international environmental science networks. In this town hall the CZO community seeks to engage the greater Earth surface and environmental science community through: 1) an update of network-scale research outcomes that could not have been achieved without the CZO approach; 2) other recent U.S. network and international activities; and, 3) reports on various upcoming opportunities to engage in CZ science through Research Coordination Networks, international programs, and the soon-to-be-announced next version of the CZO program in the U.S. All scientists interested in problems related to Earth surface and environmental science are invited.
