A multidisciplinary ice tank study, involving an international team of scientists, is shedding new light on sea ice growth processes. New findings have been made on brine distribution, on the fate of dissolved organic compounds during ice growth, and on sediment entrainment through frazil ice formation. For example, it was found that there is considerable brine migration out of and into brine channels during a freeze-melt-refreeze cycle. The study, known as INTERICE II, also is providing quantitative data for future modeling and analyses.
