Glacial geomorphology of Bonney drift, Taylor valley, Antarctica
  • Glacial geomorphology of Bonney drift, Taylor valley, Antarctica
  • The aim of this paper is to document the response of the East Antarctic Ice Sheet (EAIS) near the Dry Valleys to the excess warmth of the last interglaciation by establishing the behavior of Taylor Glacier. The AA. present a model for the deposition
  • by Taylor Glacier of Bonney drift in central Taylor Valley. Bonney drift is important because it records the penultimate advance of Taylor Glacier through central and lower Taylor Valley.
Geochronology of Bonney drift, Taylor Valley, Antarctica : evidence for interglacial expansions of Taylor glacier
  • Geochronology of Bonney drift, Taylor Valley, Antarctica : evidence for interglacial expansions of Taylor glacier
  • This study focuses on glaciogenic sediments in Taylor Valley, which features Taylor Glacier, an outlet of the peripheral Taylor Dome of the East Antarctic Ice Sheet (EAIS). Here, the AA. present the geochronology of Bonney drift.
Radiocarbon chronology of Ross Sea drift, eastern Taylor Valley, Antarctica : evidence for a grounded ice sheet in the Ross Sea at the Last Glacial Maximum
  • Radiocarbon chronology of Ross Sea drift, eastern Taylor Valley, Antarctica : evidence for a grounded ice sheet in the Ross Sea at the Last Glacial Maximum
  • More than 250 radiocarbon dates of lacustrine algae and marine shells afford a chronology for Ross Sea drift in eastern Taylor Valley. Four major drift sheets in eastern Taylor Valley are differentiated. Evidence from ice-dammed lakes in Taylor
  • Valley and from shells from McMurdo Sound suggests grounding-line retreat from the vicinity of Ross island between 6500 and 8340 C 14 yr BP. Rising sea level may have triggered internal mechanisms within the ice sheet that led to retreat, but did
Evidence from Taylor Valley for a grounded ice sheet in the Ross Sea, Antarctica
  • Evidence from Taylor Valley for a grounded ice sheet in the Ross Sea, Antarctica
Late Quaternary lakes in the McMurdo Sound region of Antarctica
  • The purpose of this paper is to assemble a comprehensive history of lake fluctuations in the Dry Valleys during the Late Quaternary, and to interpret these fluctuations, where possible, in terms of climatic and glacial changes.
The geologic basis for a reconstruction of a grounded ice sheet in McMurdo Sound, Antarctica, at the Last Glacial Maximum
  • The overall results in this paper afford a background for interpreting the glacial chronology of eastern Taylor Valley and for reconstructing a grounded ice sheet in the overall Ross Embayment at the Last Glacial Maximum (LGM)
Proglacial lake-ice conveyors : a new mechanism for deposition of drift in polar environments
  • of moraines and other ice-contact features on the valley floors, as well as for the presence of the other deposits and landforms mentioned above.
