... The paper describes a GPU-based event mechanics (GEM) model of the action of managed pack ice on a floating offshore structure. The ice cover is represented by a large number of discrete polygonal ice floes, of varying thickness. Each ice-structure contact is modeled, as is every ice-ice contact...

... This paper presents updated distributions of the temperatures, salinities and borehole strengths of old ice, as a function of time of year. Thousands of measurements are compiled from old ice floes across the Arctic. Probability of exceedance curves are used to show the more ‘extreme’ values...

... We consider an Arctic drilling platform, which must withstand seasonal ice floes and be protected against extreme ice features. Adequate ice floe thickness estimates are not discernible from satellite images, so autonomous underwater vehicles (AUVs) equipped with sonar scan the thickness...
