Rivera, A., G. Casassa, R. Thomas, E. Rignot, R. Zamora, D. Antúnez, C. Acuña & F. Ordenes (2005) : «Glacier wastage on southern Adelaide Island, Antarctica, and its impact on snow runway operations» Annals of Glaciology , 41, 57 – 62.

Resumen / Abstract.

The variations and dynamics of the southern edge of Fuchs Ice Piedmont, Adelaide Island (67845′ 09′ S, 68855′ 04′ W), Antarctic Peninsula, are presented. The snow-covered surface of the glacier has been used since the 1960s for landing aeroplanes in support of British, and more recently Chilean, operations at nearby Teniente Carvajal station (formerly known as Adelaide T). In recent years, snow conditions in the runway area have progressively deteriorated, due to increasingly early summer melting. Radio-echo sounding, global positioning system and remotely sensed data have been analyzed for mapping the crevasse and ice velocity fields, as well as the surface and subglacial topography of the area.
