From: Impact of contaminant size and density on their incorporation into sea ice
The experimental design consisted of six steps: 1) For each experiment one type of model contaminant was mixed with artificial seawater and added to columns specifically designed to generate artificial sea ice. 2) Columns underwent controlled freezing conditions. 3) Ice cores were recovered and 4) the brine was drained out of the ice core. 5) The structure of the ice was characterized by micro-X-ray-tomography (μ-CT) and finally 6) salts and contaminants were quantified in the ice, brine and liquid fraction.
