A Re-Assessment of the Mass Balance of the Lambert Glacier Drainage Basin, Antarctica

  • N. F. McIntyre (a1)

Abstract

Re-definition of the interior drainage basin Lambert Glacier, using the most recent sources of ice-surface elevations, has shown its area to be 902000 km2, that is, 17% less than previous estimates. Landsat imagery of the steepest sloping part of the basin shows there is bare ice over an area of 56000 km2. Other evidence also indicates exceptionally low mass inputs and the distribution of accumulation rates has been up-dated. The result is a positive mass balance for the interior basin (+2 Gt a–1 ) and error limits which fall below zero. This is 47% less than the most recent calculation and illustrates the difficulty in deriving mass budgets in regions where data are scarce.

Résumé

Redéfinition du bilan de masse du bassin versant du Lambert Glacier, Antarctique. Une redéfinition du bassin versant du Lambert Glacier à l’aide des plus récentes sources de l’altitude de la glace a montré que sa surface est de 902000 km2, c’est-à-dire 17% de moins que les estimations antérieures. L’imagerie Landsat de la partie la plus inclinée du bassin montre qu’il y a 56000 km2 de glace nue. D’autres évidences indiquent d’exceptionnellement faibles apports de glace et une distribution d’accumulation plus récente. Le résultat est un bilan positif pour l’intérieur du bassin (+ 2 Gta–1) et des limites d’erreur qui tombent au-dessous de zéro. Ceci est de 47% inférieur aux plus récentes déterminations et illustre la difficulté á déduire des bilans de masse pour des régions où les données sont dispersées.

Zusammenfassung

Eine Neuberechnung der Massenbilanz im Abflussbecken des Lambert Glacier, Antarktika. Eine Neuabgrenzung des inneren Abflussbeckens des Lambert Glacier auf der Grundlage der neuesten Eishöhenbestimmungen ergab deren Fläche zu 902000 km2, also 17% weniger als früher abgeschätzt. Landsat-Bilder vom steilsten Teil des Beckens zeigen dort das Vorhandensein blanken Eises über eine Fläche von 56000 km2. Andere Hinweise deuten ebenfalls auf aussergewöhnlich niedrigen Massenzustrom, weshalb die Verteilung der Akkumulationsrate neu bestimmt wurde. Das Ergebnis ist eine positive Massenbilanz für das innere Becken (+ 2Gt pro Jahr) mit Fehlergrenzen unter Null. Dies ist 47% weniger als die jüngste Berechnung und zeigt die Schwierigkeit der Massenbilanzbestimmung in Gegenden, für die nur wenige Daten vorliegen.
