OD-OI80 RELATIONSHIPS AND THE THERMAL HISTORY OF BASAL ICE NEAR THE MARGINS OF TWO GLACIERS IN
ABSTRACT. When plotted on a SD-SISO 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...

| Summary: | ABSTRACT. When plotted on a SD-SISO 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. |
