Moving the Field into the Lab: Simulation of Water and Heat Transport in Subarctic Peat
ABSTRACT Large climate chambers are suitable to simulate, at or close to field scale, the annual freezing and thawing of layered peat in subarctic active layers above permafrost. An experiment in a climate chamber at the University of Western Ontario was designed to freeze and thaw four peat cores 6...
