Short summary

This study measured how quickly carbon dioxide was absorbed/released from sea ice to the air. We used a method that had never been tested over landlocked sea ice. To avoid water vapor ruining the carbon dioxide measurement, we dried the sample air before it went to the gas analyzer. This gave values that were more credible than those found by previous studies. We showed that this method will be useful for studying the processes which affect carbon dioxide exchange between sea ice and air.
