Mass balance of two High Arctic plateau ice caps
ABSTRACT. Mass-balance measurements have been renewed on two small ice caps on north-eastern Ellesmere Island. Original stake networks were established in 1972 and 1976. Since then, both ice caps have experienced significant mass losses averaging-70 to-140 kg m- 2 a-l. They have also decreased in ar...

| Summary: | ABSTRACT. Mass-balance measurements have been renewed on two small ice caps on north-eastern Ellesmere Island. Original stake networks were established in 1972 and 1976. Since then, both ice caps have experienced significant mass losses averaging-70 to-140 kg m- 2 a-l. They have also decreased in area. The equilibrium line in this area has averaged around 1150 m for the last decade or so. ' The ice caps are remnants of former climatic conditions and are out of equilibrium with contemporary climate. By 20-21 August there was "partial cover of winter snow all around the ice margin for at least a kilometer" (Hattersley-Smith and Serson, 1973). A network of eight |
