| Summary: | Understanding the interaction between oil and sea ice is essential in the development of oil spill detection and response technology in the Arctic. Laboratory experiments were performed to examine oil migration in sea ice during the cold phase and during warming, and investigate the behavior of different oils in sea ice to identify suitable substitute oils for crude oil. Vegetable oil and Troll B crude oil were injected underneath laboratory-grown sea ice with oil lenses either 1 cm or 3 cm in thickness. Results show similar behavior of vegetable oil and crude oil in sea ice both shortly after oil injection and during the warm phase. Further, results are independent of lens thickness. The implications of this result are discussed. In addition, the impact of cylindrical confinement of ice is shown on crystal and brine channel structure, and the energy balance of the tank are discussed. publishedVersion
