Learn More About CZ Net

CUAHSI is serving as the Coordinating Hub for the Critical Zone (CZ) Collaborative Network. The 5-year cooperative agreement became effective September 1, 2020.

Our collaborators for this new venture are Jill Baron, U.S. Geological Survey; Beth Boyer, Pennsylvania State University; Chris Calloway, Renaissance Computing Center, University of North Carolina Chapel Hill; Jeff Horsburgh, Utah State University; and Kerstin Lehnert, Lahmont-Doherty Earth Observatory of Columbia University. This is a strong team, all of whom have experience with Critical Zone Science and the previous Critical Zone Observatory Network.

Operation of the Hub will include four primary tasks:

  1. Enhance and integrate existing data services operated by CUAHSI and EarthChem to support the CZ community (Horsburgh, Lehnert, and Calloway): We intend to establish cyberinfrastructure with a distributed architecture that links existing data facilities and services, including HydroShare, EarthChem, SESAR (System for Earth Sample Registration), Open Topography and eventually other systems via a central CZ Hub that provides services for easy data submission, integrated data discovery and access, and computational resources for data analysis and visualization.
  2. Support discovery through community synthesis activities and via access to community data and modeling cyberinfrastructure (Baron and Boyer). We will utilize the resources of the USGS John Wesley Powell (JWP) Center for Analysis and Synthesis to catalyze CZ synthesis. We will follow the established and successful protocols of the JWP Center in the formation of three synthesis groups of the 5-year life of the project.
  3. Broaden the CZ community through outreach and education activities (Boyer and Bales): We aim to create a broader, more inclusive community dedicated to CZ research; to promote dissemination of CZ information and resources to stakeholder communities inside and outside of academia; and to use CZ science as a platform to inspire STEM learning.
  4. Enhance collaboration among CZ Thematic Clusters through coordination, sharing, community meetings, and outreach (All); We will manage the web presence of the network; grow collaborations with under-represented CZ scientists through a partnership with an existing CZ RCN; site training through grants; and facilitate meetings among network scientists and others in the community.

CZ Net includes 9 Thematic Clusters across the US that are conducting basic research concerning the structure, function, and processes of the critical zone:

  • CINet: Critical Interface Network in Intensively Managed Landscapes
  • The Coastal Critical Zone: Processes that transform landscapes and fluxes between land and sea
  • Bedrock controls on the deep critical zone, landscapes, and ecosystems
  • Dynamic Water Storage -- Quantifying controls and feedbacks of dynamic storage on critical zone processes in western montane watersheds
  • Urban Critical Zone processes along the Piedmont-Coastal Plain transition
  • Patterns and controls of ecohydrology, CO2 fluxes, and nutrient availability in pedogenic carbonate-dominated dryland critical zones
  • Dust in the Critical Zone from the Great Basin to the Rocky Mountains
  • Using Big Data approaches to assess ecohydrological resilience across scales
  • Geomicrobiology and Biogeochemistry in the Critical Zone
