Distributed Environmental Sensing
"Nothing tends so much to the advancement of knowledge as the application of a new instrument.”
– Sir Humphry Davy, early exponent of the scientific method, scientist, inventor.
Developments in sensor array technologies are providing significant new tools for understanding fundamental ecosystem processes

Implementing CENS technology in ecological and ecosystem research
• Long-term ecological research: monitoring ecosystem processes
• Global change studies: carbon cycles and biogeochemical fluxes; forest structure; coastal food web structure
• Ecophysiological research: modeling physiological processes and their control by microclimate
• Organismal ecology: phenology; acoustical and video monitoring of animal behavior and activities; marine phytoplankton dynamics
• Environmental education

Detecting global change at multiple spatial and temporal scales
Large networked arrays of environmental sensors can provide early warnings of subtle environmental changes

Understanding the spatial and temporal patterns
in the dynamics of terrestrial carbon cyclesLow spatial and temporal density of eddy covariance measurements
limit our understanding of canopy-level CO2 fluxes
CENS technologies will contribute to many national and international programs investigating environmental gas fluxes

Understanding how microclimate controls ecophysiological processes
Microclimate parameters are fundamental elements of ecophysiological models
