δD-δ18O Relationships and the Thermal History of Basal Ice Near the margins of two Glaciers in Lyngen, North Norway

Abstract

When plotted on a δD-δ18O diagram, the isotope values of basal ice formed by refreezing of melt water beneath the cold-based margin of a corrie glacier lie on a straight line with a slope of 5.5. This freezing slope differs from a slope of 7.2 for the basal ice layer of the cold-based ice cap, Balgesvarri, which has not undergone refreezing. The latter slope is similar to that of 7.7 for the local precipitation. Co-isotope measurements from the two glaciers support the association of subglacial debris entrainment with refreezing processes.
