Resonant Acoustical Models of Thin Ice Formation Data Management Plan
Abstract
The mechanical properties of a water-air interface change profoundly as ice forms and grows, and with them the appropriate models that describe the resonant response of the surface. Existing models focus on ice that is meters thick and can be readily modeled as either a bulk elastic medium or an elastic plate. On the other hand, water is a fluid without shear support. While the fluid-fluid and elastic plate models are appropriate in their respective limits, the points along the transition from water into thick ice where each model is valid, as well as the models for intermediate ice thicknesses, are unknown. However, it is known that, for sufficiently thick samples, acoustical resonances in ice depend on the material properties of the ice, allowing one to estimate the ice thickness and bending strength. We hypothesize that ice, from its formation and growth up to a 4 cm thickness in laboratory conditions, will exhibit a measurable acoustic modal response that can be used to extract the physical parameters and associated mechanical models of the ice. The upper limit of 4 cm was chosen because empirical evidence suggests that this thickness is the smallest thickness that can support the weight of a pedestrian on skis.
