Home - Denitrification Research Coordination Network

Integration Across Landscapes and Waterscapes

The Network

(Updated 8/6/2008)

The Denitrification RCN network is open to all individuals (both inside and outside the US) who are involved in denitrification research in ecosystems ranging from terrestrial to aquatic (both freshwater and marine) and human engineered systems. This includes a broad range of scientists who are measuring and modeling denitrification and associated controlling factors, statisticians, remote sensing specialists and instrument and sensor development specialists, among others. People from academic institutions, government agencies, environmental managers and private companies are welcome.
