High-Latitude Ecosystems as Sources and Sinks of Trace Gases (HESS), 1994 or earlier - 1999

The primary goals of HESS were to estimate the strength of trace gas sources and sinks in high-latitude ecosystems on a global scale, determine the principal ecological and environmental correlations and understand the importance of them on environmental change. HESS conducted the Northern Wetlands Experiment campaign, which looked at the importance of Northern wetlands as sources of biogenic gases contributing to the atmosphere. The activity merged into BATREX in 1999.
