Salinity and Porosity of Laboratory Grown Young Pancakes

An indoor experiment to study pancake ice growth in a wave field has been conducted in the ARCTECLAB of the Hamburgische Schiffbau-Versuchsanstalt (HSVA). This unique facility was equipped with two distinct wave tanks in the same cold room. Two wave makers were operated independent of each other in two identical flumes. Pancake ice growth was monitored in these two separate wave tanks. In addition to the two wave tank tests, the authors also grew ice under calm water condition in the same room using a box with insulated walls and bottom. Each test began with open water condition. The duration of each test was about 7 hours long. This report summarizes salinity and porosity measurements of the ice samples collected during the tests. The salinity values were found to be much higher than previously reported from field studies. There was no field porosity data that could be found in the literature to compare with.
