About John Gamon

Dr. John Gamon studies the “breathing of the planet” – the exchanges of carbon and water vapour between the biosphere and the atmosphere that affect ecosystem productivity and help regulate our atmosphere and climate. Of particular interest are the effects of disturbance (fires, succession, weather events and climate change) on these basic processes. Additional research questions involve the detection of plant physiology, ecosystem function, species composition, and biodiversity using non-contact sampling methods. Much of this work is done with optical monitoring (remote sensing and automated field methods), and entails the development of new monitoring methods and related informatics tools.

To encourage wider usage of these methods, Dr. Gamon co-founded SpecNet, (Spectral Network), a network of collaborating sites and investigators using optical sampling methods (particularly spectral reflectance) to study ecological questions. Dr. Gamon conducts fieldwork in a range of ecosystems from the Arctic to the Tropics.
