An alternative interpretation is provided by Kristoffersen et al. (2004) who argue that the mapped idge were formed Quaternary Research 63 (20Introduction A diversity of hypotheses and speculations exists about past glacial conditions in the Arctic Ocean. These vary from sea-ice-free conditions with limited glaciation on surrounding shelves (Olausson, 1985) to huge floating ice shelves, N1 km thick and fed by large ice caps that occupied the surrounding shelves (e.g., Grosswald, 1980; Hughes et al., 1977; Mercer, 1970).
