The case for a stable East Antarctic Ice Sheet: the background
The case for a stable East Antarctic Ice Sheet
There are two primary views concerning the stability of the East Antarctic Ice Sheet. After summarising the status of the two hypotheses, the AA. explain the rationale for this volume. Building on the Vega Symposium of April 1993, it presents
the case for the stability of the East Antarctic Ice Sheet and includes new work on terrestrial geomorphology and geology, marine cores and ice-sheet modelling.
Frostdynamik und Permafrost in eisfreien Gebieten der Antarktischen Halbinsel. (Frost dynamics and permafrost in ice-free areas of the Antarctic Peninsula)
In the lower oceanic Antarctic where particular climatic conditions are found, a special type of periglacial geosystems exists with geomorphic effected cryodynamics. The approaches to regional modelling are to be further developed because
the theories of periglacial arctic environments are not sufficient for regional explanation in the periglacial Antarctic.
Late Tertiary Antarctic paleoclimate and ice-sheet dynamics inferred from surficial deposits in Wright Valley
The case for a stable East Antarctic Ice Sheet
The evidence of persistent cold paleoclimate contradicts the postulated Pliocene deglaciation of East Antarctica, which requires atmospheric temperatures 20°C warmer than present to produce melting ablation surfaces on the East Antarctic Ice Sheet
. Furthermore, an East Antarctic outlet glacier has not expanded into east-central Wright Valley in at least the last 3.8 Ma, thus precluding ice-sheet overriding of the Dry Valleys region during this interval. Overall, Wright Valley data imply that the adjacent
East Antarctic Ice Sheet has been stable for at least the last 3.8 Ma.
Late Quaternary environmental changes in the Antarctic and their correlation with global change
Based on records from both Antarctic Ice Free Areas and Ice Cores, a brief discussion concerning the assumed disaster in the coming 50-100 years is given in this paper.
Lake sediment cores from the Antarctic peninsula and surrounding islands
Sediment cores from two lakes on the Antarctic Peninsula, Hidden Lake on James Ross Island and Lake Boeckella in Hope Bay, are described, analysed and dated with regard to climatic changes during the Holocene.
The dry areas of the Antarctic are extreme deserts. Because of the cold they are not subjected to rainfall and geochemical separations can take place which would be destroyed by flowing water in the more temperate deserts. The distribution
Zur Tektonik und Minerogenie Antarktikas. (On tectonics and minerogeny of the Antarctic)
Starting from the tectonical subdivision of the Antarctic and from the tectogenetical epochs, minerogenetical conclusions are done and comparisons are drawn with other southern continents. From this are resulting hints on those territories, which
On the origin, nature and uses of Antarctic ice-sheet radio-echo layering
In this article, the nature, origin and uses of internal Antarctic ice-sheet layering, observed on 60 MHz RES data, are investigated. In doing so an insight into several aspects of modern Antarctic glaciological research is provided : correlating
