Data sets

Carbon dioxide flux measurements from a seasonally sea ice-covered marine environment in the Canadian Arctic Brent Else and Brian Butterworth https://doi.org/10.5281/zenodo.15191010

Short summary

Observations of carbon dioxide transfer between water and air were measured at a seasonally ice-covered marine location using the eddy covariance method. The goal was to determine how sea ice influences water-air transfer of carbon dioxide by season. During full ice cover in winter, ice acted as a barrier to transfer. In spring, melt water absorbed carbon dioxide from the air. In fall, freezing released carbon dioxide from water to the air.
