Ring of Fire Lakes Survey

Body: 

Ring of Fire Lakes Survey

Limnological surveys are underway in the “Ring of Fire” area, the location of a major chromite deposit discovery in the Far North of Ontario. Surveys of ~20 lakes in the Ring of Fire area will begin in July 2012 to characterize the range of physical, chemical, and biological characteristics (zooplankton and phytoplankton) in lakes of the region (pre-development). Data from this survey will be compared to similar zooplankton surveys that have recently been completed in other areas of the Far North. By comparing regional patterns in zooplankton community composition we will determine if zooplankton communities and their relationships to environmental factors are similar across northern Ontario. This comparative study will determine if we can transfer existing knowledge of zooplankton/environment/ stressor relationships from more southern lakes to assist with the management of lakes in the northern boreal region. Survey planning will involve local people from First Nations communities in the area. Our overall goal is to improve the scientific understanding of lakes in the north, to allow better predictions of their sensitivity to future industrial development or changes in climate.
