Carbon Dynamics During the Formation of Sea Ice at Different Growth Rates ...
Controlled laboratory experiments have shed new light on the potential importance of brine rejection during sea-ice formation for carbon dioxide sequestration in the ocean. We grew ice in an experimental seawater tank (1 m3) under abiotic conditions at three different air temperatures (−40°C, −25°C,...
