| Hurd Peninsula ice cap spans an area of ca. 13.5 km2. Its two main basins are Johnsons, a tidewater glacier, and Hurd Glacier, ending on land, both with areas about 5 km2. The annual surface mass balances, averaged over the 10-year period, are slightly negative (?0.15±0.10 m w.e. a?1) for Hurd Glacier, and very slightly positive (0.05±0.10 m w.e. a?1) for Johnsons Glacier. These mass losses are, however, smaller (almost by half) than the average geodetic mass balances estimated for the period 1956-2000 showing that the rate of mass loss has decelerated in spite of continued regional warming. Interestingly, this seems to be due not just to the observed increase in accumulation in the region, but, at least in the case of Hurd and Johnsons glaciers, also to a decrease of surface melt associated to the smaller amount | |
