Welcome to the IPY Metadata Catalog
PPS Arctic Canada (Present processes, Past changes, Spatio-temporal variability in the Arctic delimitation zone, Canada) is the Canadian component of PPS Arctic, an IPY endorsed research program on the causes and consequences of change of the forest-tundra ecotone (the treeline).
Together with international researchers we developed common protocols and collected data during IPY to examine change at the treeline. In the summers of 2007-09, we collected data at over a dozen locations in the Yukon, Northwest Territories, Nunavut, northern Manitoba, northern Quebec and Labrador.
