Supersaturation reduces with biological uptakes and increases with calcium carbonate dissolution.

Typical temperature - supersaturation regions can be identified for the «onset» of ice nucleation of these different particle types, but the various particle sizes and activated fractions reported in different studies have to be taken into account when comparing results obtained with different methodologies.
