Short summary
The active layer above permafrost experiences seasonal freezing and thawing cycles. The thickness, and climate-driven change in thickness, of this active layer impacts infrastructure performance, global carbon release, among others. We show how to use gravitational scaling in laboratory experiments that describe the response of the active layer. By using gravity scaling, we can conduct less expensive experiments that still describe the response of actual frozen ground at the prototype scale.
