Science / project plan

The contribution of sea-ice-covered regions to the global air-sea CO2 exchange was, until recently, assumed to be insignificant primarily because sea ice was considered impermeable. The discovery of a sea ice CO2 pump and the recognition that extensive and productive microbial communities exist within sea ice, however, has changed this general perception. The main focus of this study is to improving the methods for measuring in situ pCO2 concentrations in sea ice by using a gas tight chamber. In Young Sound measurements of bulk TA, TCO2, pH temperature, salt conditions in sea ice is compared with measurements in a gas tight chamber. Therefore these results can be used to verify if algorithms calculating pCO2, pH, TA, TCO2 in the seawater can be used to calculate in situ pCO2 pH, TA, TCO2 in sea ice.
