Project Description

Interactions between ocean waves and sea-ice are essential to understanding sea-ice morphology, especially in the context of global warming [3]. Ocean waves are believed to have contributed to the massive ice reductions that have occurred in the summer Arctic sea-ice cover over the last 20 years. Of great interest is the marginal ice zone (MIZ), which is the fragmented part of the ice cover closest to the open ocean and is a very dynamic region strongly affected by incoming ocean waves. To predict and explain ice interaction with ocean waves and structures, such as ships and platforms, linear and nonlinear mathematical models of wave propagation and wave scattering have been developed over the years, with the sea-ice normally being modelled as a compliant plate floating on water in which flexural-gravity waves are free to propagate. Discrete and continuous models of broken ice and ice floes are also available but less developed. New linear and nonlinear models will be developed to study attenuation rates on waves in MIZ. Comparisons of the results with field data and experiments will be undertaken to assess the validity of the new models.

Funding Notes

This PhD project is in a Faculty of Science competition for funded studentships. These studentships are funded for 3 years and comprise UK/EU fees, an annual stipend of £15,009 and £1,000 per annum to support research training. Overseas applicants may apply but they are required to fund the difference between home/EU and overseas tuition fees (which are detailed on the University’s fees pages at View Website . Please note tuition fees are subject to an annual increase).
