AB: The basic tenets of bulk and interfacial thermodynamics, equilibrium and nonequilibrium statistical mechanics, and transport theory are standard tools in many areas of physical science and engineering, and are essential for any attempt at explaining the phase behavior of sea-ice and the crystal growth phenomenon that characterize it on a macroscopic scale. Because the effective (homogenized) properties of sea-ice underlie its large scale dynamic and thermodynamic properties a rigorous predictive theory is warranted. In this talk, I describe where these properties come from, how we can study them in a laboratory setting, and how these properties manifest themselves in the polar regions. Due to the fact that at least some aspects of nearly all of the phase change problems we observe in sea ice are found in a host of other systems, I will emphasize the connections between floating ice and other materials of geophysical and technical interest.
