Abstract:

Seymour (Marambio) and Vega Islands occur within the continuous permafrost zone of the northeastern Antarctic Peninsula. Results are presented of investigations on the occurrence, distribution, morphology and genesis of ground ice, a key aspect of permafrost research in this region. According to its morphology, ice content, buried ice type and possible upper Quaternary conditions, permafrost is divided into two cryoformations: epigenetic and syngenetic. Based on field and remote-sensing data, 76.6 km2 of Seymour Island and 81.0 km2 of Vega Island are characterized by permafrost, with estimated ice contents of 0.06 and 1.41 km3, respectively. Different genetic ground-ice types are distinguished and a regional morphogenetic classification of ground ice is proposed.
