SUMMARY:What the experimental measurements of wave decay can tell us about
  the physics - Mike Meylan (University of Newcastle\, Australia)

DESCRIPTION:The critical problem with modelling the wave propagation throu
 gh ice is that we do not know the physics behind the mechanism (or mechani
 sms) for wave energy absorption. This lack of knowledge is a crucial short
 coming and presents a significant obstacle to progress.\nThe key result of
  my work during the sea ice program was to analyse the experimental data a
 nd to show that if the attenuation is a slow process with respect to the t
 ime scale (which is the wave period)\, then it should follow a power law a
 nd that the exponent of this power law should indicate the possible physic
 s behind the energy loss.&nbsp\;\nI will discuss this in detail and show h
 ow almost all the models for wave decay fit within this paradigm.
