Objective(s): To quantify the vertical flux of carbon in the Resolute Passage waters both before and after the breakup of the ice cover; to link the intensity of this flux to the production of ice algae and phytoplankton, as well as to the grazing of zooplankton organisms.

Project Description: The researchers will be examining small marine organisms (algae, zooplankton and phytoplankton) to determine their influence on global warming. Carbon is necessary for the production of carbon dioxide (CO2), and increase levels of CO2 in the atmosphere can contribute to an increase in the earth's overall temperature. The study will examine how these small marine creatures can reduce carbon levels in the water and, therefore, in the atmosphere as well.
