The effect of sea ice on the Arctic marine carbon sink

My PhD research aims to dramatically increase the quantity and quality of direct CO₂ exchange measurements between the marine environment and the atmosphere to capture the influence of marginal sea ice zones on the Arctic CO₂ sink. A remote weather station in the Canadian High Arctic, approximately 35 km west of Cambridge Bay (Iqaluktuuttiaq), Nunavut will be used to obtain high frequency measures of gas exchange, in this case CO₂. These direct measurements, combined with the collection of sea ice cover concentrations and sea water and ice CO₂ concentrations will significantly contribute to the parameterization of CO₂ flux models in polar oceans, which currently do not effectively account of the presence of sea ice. Ultimately this research will contribute to more accurate assessments of global CO₂ cycling, as nearly 10% of oceans experience ice fractioned portions.
