Abstract	A small island can be taken as being representative of a man- made offshore structure. A comprehensive study of ice interaction with such an island and response of the ice sheet to environmental driving forces was carried out over the winter 1984/85. Measurements included meteorological and oceanographic factors as well as ice-cover movements and in-situ stresses. Tidal variations, both semi-diurnal and fortnightly, appear to be responsible for variable horizontal ice-cover movement rates and hence cyclical variations in measured ice stresses. Maximum total load generated on the island was approximately 60 MN, equivalent to an average stress of 300 kPa over the top 1 m of the ice thickness and 200 m width. Local pressures over an area of 0.5 m2 reached a maximum of 500 kPa.
