Ikaite (CaCO 3 •6H 2 O) is a metastable calcium carbonate mineral that forms at low temperature and/or high pressure. Ikaite precipitates in sea ice and may play a significant role in air–sea CO 2 exchange in ice covered seas and oceans. However, the spatial and temporal dynamics of ikaite in sea ic...
