Changes in the salinity and porosity of sea-ice samples during shipping and storage

A theoreti cal examination of salinity and porosity changes introduced in sea-ice samples by brine expulsion and gas entrapment caused by thermal cycling during shipping and storage shows that in extreme cases such effects can be significant, resulting in 15 % reductions in porosity (1/). More representative scenarios give porosity changes of less than 2% which, assuming that ice-property variations scale with n 1 / 2 , result in property variations of less than 1%.
