ANTARCTIC ICE SHEET [4 records]

Record 1 2009-02-12

English

Subject field(s)
  • Titles of International Programs
  • Glaciology
OBS

The West Antarctic Ice Sheet (WAIS) is the segment of the continental ice sheet that covers West (or Lesser) Antarctica, the portion of Antarctica west of the Transantarctic Mountains. The WAIS is classified as a marine-based ice sheet, meaning that its bed lies well below sea level and its edges flow into floating ice shelves. The WAIS is bounded by the Ross Ice Shelf, the Ronne Ice Shelf, and outlet glaciers that drain into the Amundsen Sea.

English

Subject field(s)
  • Geological and Other Scientific Names
  • Glaciology
  • Polar Geography
  • Environmental Economics
CONT

Most of the early attention to the issue of sea level rise and greenhouse warming was related to the stability of the West Antarctic ice sheet. Parts of this ice sheet are grounded far below sea level and may be very sensitive so small changes in sea level or melting rates at the base of adjacent ice shelves.

OBS

L'Antarctique (continental) est formé de deux ensembles, de part et d'autre des chaînes transantarctiques. [...] L'Antarctique oriental, vestige du continent de Gondwana [...]. L'Antarctique occidental (de la péninsule Antarctique à la mer de Ross) est une suite d'arcs insulaires.

OBS

On nomme «Antarctide» l'ensemble continental et insulaire de l'hémisphère Sud. L'«Antarctique» englobe l'Antarctide et la zone océanique, l'océan Austral (le nom actuel de l'océan Antarctique), la partie des trois océans (Atlantique, Pacifique, Indien) formant une ceinture continue autour de l'Antarctide.

Record 4 1993-11-30

English

Subject field(s)
  • Environmental Economics
  • Climate Change
  • Air Pollution
CONT

There is no firm evidence to suggest that the Antarctic ice sheet in general, or the West Antarctic ice sheet in particular, have contributed either positively or negatively to past sea level rise.

French

Domaine(s)
  • Économie environnementale
  • Changements climatiques
  • Pollution de l'air
CONT

Il conviendrait de développer les observations, à partir de satellites, sur les variations des températures à la surface des océans, sur les changements dans l'étendue des glaces marines polaires, sur les modifications de la superficie et des hauteurs des inlandsis groenlandais et antarctique, autant de signaux d'une éventuelle augmentation de volume des eaux océaniques.

OBS

Inlandsis : vaste glacier occupant les hautes latitudes (Antarctique, Groenland). Syn. glacier continental.
