Calcium carbonate as ikaite crystals in Antarctic sea ice
[1] We report on the discovery of the mineral ikaite (CaCO 3 6H 2O) in sea-ice from the Southern Ocean. The precipitation of CaCO 3 during the freezing of seawater has previously been predicted from thermodynamic modelling, indirect measurements, and has been documented in artificial sea ice during...
