Bacteria beneath the West Antarctic Ice Sheet
Environmental Microbiology, 2009Summary Subglacial environments, particularly those that lie beneath polar ice sheets, are beginning to be recognized as an important part of Earth's biosphere. However, except for indirect indications of microbial assemblages in subglacial Lake Vostok, Antarctica, no sub‐ice sheet environments have been shown to ...

Is the Antarctic ice sheet growing?
Nature, 1992A brief review is presented of recent observations of surface accumulation on Antarctica. It is concluded that it is as yet too early to say with confidence whether the ice sheet has recently been growing or shrinking, given the variability in accumulation pattern and the larger uncertainties in melting and calving.

Pleistocene Collapse of the West Antarctic Ice Sheet
Science, 1998Some glacial sediment samples recovered from beneath the West Antarctic ice sheet at ice stream B contain Quaternary diatoms and up to 10 8 atoms of beryllium-10 per gram. Other samples contain no Quaternary diatoms and only background levels of beryllium-10 (less than 10 6 atoms per gram ...

Historic simulations of the Antarctic Ice Sheet with the Parallel Ice Sheet Model
2021<p>Large uncertainties in Antarctic sea level projections are related to ocean-driven melting (Seroussi et al., 2020; Jourdain et al., 2020; Reese et al., 2020; Edwards et al., in press) and the marine ice sheet instability (Robel et al., 2019).

Science, 1970
The Antarctic surge theory of Pleistocene glaciation is reexamined in the context of thermal convection theory applied to the Antarctic ice sheet. The ice sheet surges when a water layer at the base of the ice sheet reaches the edge of the ice sheet over broad fronts and has a thickness sufficient to drown the projections from the bed that most ...
