2009, MS, University of Cincinnati, Arts and Sciences : Geology.
Some short term climate reversals on the order of centuries are perceived to be generated by coupled feed backs in individual systems. It has been hypothesized that a significant pulse of fresh deglaciated water could be responsible for the capping of the upwelling and gyrecirculation in the North Atlantic Ocean consequently forcing a cooling in global temperature and a climate reversal. The catastrophic drainage of Lake Ojibway into the North Atlantic is a proposed trigger for the 8200 Cal. BP year cooling event. The objective of this study is to identify the stratigraphic signature of lake drainage and to assign some chronology to the stratigraphy. A stratigraphic record was developed based on cores from eleven lakes in transect from northeast Ontario 240 km southeast into the province of Quebec. The interpreted stratigraphy consists of a post Cochrane re-advance, ice proximal and distal sedimentation before final drainage and post drainage landscape stabilization. This stratigraphic record of Lake Ojibway provides a unique record which may be incorporated into a larger data set. Refined chronostratigraphic results may be integrated into larger studies with the objective of demonstrating a causal relationship between lake drainage, the capping of the North Atlantic circulation and a reversal in climate regime within the warmer Holocene.
