SIPW05 - SIP Follow on: Mathematics of sea ice in the twenty-first century

The critical problem with modelling the wave propagation through ice is that we do not know the physics behind the mechanism (or mechanisms) for wave energy absorption. This lack of knowledge is a crucial shortcoming and presents a significant obstacle to progress. The key result of my work during the sea ice program was to analyse the experimental data and to show that if the attenuation is a slow process with respect to the time scale (which is the wave period), then it should follow a power law and that the exponent of this power law should indicate the possible physics behind the energy loss.  I will discuss this in detail and show how almost all the models for wave decay fit within this paradigm.
