Objective(s): To study active layer hydrology and the changes in energy input into the active layer from its initial formation in the spring to its maximum thickness in August; to examine how soil moisture in the active layer changes over time; to examine weathering in the active layer and upper layer of the permafrost; to study groundwater flow and chemistry as it influences the chemistry of Colour Lake.

Project Description: The researchers are interested in understanding how physical factors (snowmelt, rainfall, solar radiation) play a role in thawing the upper part of the ground each year during the spring and summer. Instruments in the ground will collect data that will estimate how much energy (from the sun) is entering into and melting the frozen ground. Other instruments will measure snowmelt, rainfall and the chemistry of the water. This is a multi-year study.
