The Mistik Askiwin Dendrochronology Laboratory (MAD Lab) was launched in the spring of 2014 after moving to Saskatoon from Mount Allison University in Sackville, New Brunswick. The MAD Lab was formed to investigate tree-ring related research questions in many areas of Canada.  The initial focus of the MAD Lab was to establish extensive tree-ring chronologies in the Atlantic region.  These chronologies form the foundation of various projects, from researching annually-resolved proxy climatic records for the Atlantic region, to dating historic structures in Maritime Canada. Now we have moved on to extensive tree-ring work across all Saskatchewan and western Canada.
