snow radar data to study spatial and temporal patterns of snowfall rates. Antarctica BPRC scientists have obtained ice cores from multiple locations on the Antarctic Ice Sheet. The Transantarctic Mountains bisect the continental ice sheets, with different ice flow dynamics on either side. Radarsat (radar images collected by orbiting satellites) is being used to map the ice sheets. Ice sheet flow into the ocean is increasing and in western Antarctica, the ice stream is draining into the Ross Ice Shelf with marked acceleration. In March 2000, the largest observed iceberg in history broke away from the Ross Ice Shelf. Peru The Qori Kalis Glacier in Peru, the main outlet of the Quelccaya Ice Cap, is in retreat. The terminus of the glacier has shown reduction since 1963, with dramatic increases since 1980. Africa Lonnie Thompson has led research expeditions to the glaciers atop Mount Kilimanjaro. At the present rate of Kilimanjaro glacier decline, it is predicted that the snow cover will be completely gone by 2020, and the glacier may no longer exist by 2023.
