| Abstract | A project was carried out over the winter of 1985/86 to measure ice forces on the Nanisivik wharf and associated environmental factors. The ice regime was land-fast first year sea ice which attained a maximum thickness of 1.6 m in May. Five panel-type transducers 1-m wide and divided into 0.5-m vertical sections were frozen into the ice cover 40-m out from the vertical wharf face. Measured ice pressures in the panels indicated that the majority of the ice pressure was in the top 0.5 m of the ice cover and all panels responded in a similar/synchronous manner to temperature and tidal inputs. Major loading events were systematic associated with a large or rapid temperature increase. Superimposed on these events were ice pressure oscillations having a frequency twice the tidal frequency. Maximum measured ice pressure on one panel section was 450 kPa. Averaged ice pressure measurements reached a maximum of 155 kN/m. A conceptual model relating ice pressure to tide is proposed to guide interpretation. |
