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.
Limited pliocene glacier extent and surface uplift in middle Taylor Valley, Antarctica
The purpose of this paper is to assess the degree of stability/instability of the East Antarctic Ice Sheet during the Pliocene by dating and mapping surficial deposits in middle Taylor Valley in the Dry Valleys region of southern Victoria Land.
Late Tertiary Antarctic paleoclimate and ice-sheet dynamics inferred from surficial deposits in Wright Valley
. 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
Long-term rates of denudation in the Dry Valleys, Transantarctic Mountains, southern Victoria Land, Antarctica based on in-situ-produced cosmogenic 21Ne
Concentrations of cosmogenic 21Ne measured in quartz have been used to estimate long-term rates of denudation for contrasting landscape components in the Dry Valleys area. Samples of Beacon Supergroup sandstones and granitic basement were collected
with the preservation of volcanic deposits dating back to the mid-Miocene, these 21Ne data demonstrate that only minimal modification of the landscape has occurred in the Dry Valleys over at least the past 15 Ma.
