Whereas lake ice thickens vertically with a planar freezing interface, sea ice grow th is cellular A theoretical treatment of the planar-cellular transition under natural... [Pg.383]

Cellular freezing of natural waters implies a much larger interstitial solute incorporation in form of liquid brine than planar freezing. The planar-cellular transition may therefore be identified as a change to a milky ice appearance or by a sharp increase in the effective solute distribution coefficient Systematic observations of the... [Pg.383]

Figure 4 Planar-cellular transition during downward freezing of saline solutions in several laboratory studies compared to the present predictions of critical interface (dotted line) and bulk far-field concentrations (dashed and solid curves). The circles are the most 7 eliable observations in terms of conPol of the growth conditions.

The change in crystal orientation from primarily vertical to horizontal and the planar-cellular transition appear to be closely related. [Pg.389]

Several authorshave conceptually related the transition from planar to cellular freezing of ice to the condition of constitutional supercooling Here the theoretical framework of morphological stability theory for a planar interface is combined with simple models of diffusion and free convection to derive the transition salinity in dependence on growth conditions. [Pg.383]
