Abstract

The structure of sea ice (NaCl-doped water) differs from freshwater ice. In this project, we will be investigating how ice grows when doped with various solutes such as sodium chloride and sulfuric acid. There are two projects that were investigated. The first project consisted of finding the velocity of the ice growth of deionized water, saltwater, and water doped with sulfuric acid. The second project consisted of observing how the polycrystalline structure of ice differs between deionized water, saltwater, and water doped with sulfuric acid.
