Molecular support for Pleistocene persistence of the continental Antarctic moss Bryum argenteum [PDF]

, 2010
We examined sequence variation of ITS and phy2 for Bryum argenteum from Antarctica, sub-Antarctic, New Zealand and Australia to understand better taxonomic delimitations and resolve relationships between these geographic regions. Bryum argenteum has been

The sensitivity of Cook Glacier, East Antarctica, to changes in ice-shelf extent and grounding-line position

Journal of Glaciology, 2022
The Wilkes Subglacial Basin in East Antarctica contains ice equivalent to 3–4 m of global mean sea level rise and is primarily drained by Cook Glacier.

Estimating the distribution of demand for Antarctic krill (Euphauisa superba) from land-based predators at South Georgia [PDF]

, 2007
South Georgia is renowned for the abundance of Antarctic krill (Euphausia superba) and a range of krill predators. Variability in krill availability at a range of scales, and the consequences of this for predator-prey interactions, mean that quantifying ...

Application of Synthetic Aperture Radar (SAR) Imagery on Antarctic Glaciology

Antarctic Record, 1995
Antarctic sea ice and ice sheet were studied using the ERS-1 and JERS-1 SAR images received at Syowa Station in 1991-1993. Analysis was mainly done for sea ice in Lutzow-Holm Bay, ice streams flowing into the bay, ice sheet near the coast and inland ...

Seasonal and spatial variations in the ocean-coupled ambient wavefield of the Ross Ice Shelf

Journal of Glaciology, 2019
The Ross Ice Shelf (RIS) is host to a broadband, multimode seismic wavefield that is excited in response to atmospheric, oceanic and solid Earth source processes.

Recent trends in melting conditions on the Antarctic Peninsula and their implications for ice-sheet mass balance and sea level [PDF]

, 2006
Long-term records from meteorological stations on the Antarctic Peninsula show strong rising trends in the annual duration of melting conditions. In each case, the trend is statistically significant and represents a major increase in the potential for ...

Change at 85 degrees south: Shackleton Glacier region proglacial lakes from 1960 to 2020

Annals of Glaciology, 2023
Over the last two decades, anomalous warming events have been observed in coastal Antarctic regions. While these events have been documented in the Ross Sea sector, the Antarctic interior is believed to have been buffered from warming.

Comparison of elastic moduli from seismic diving-wave and ice-core microstructure analysis in Antarctic polar firn

Annals of Glaciology, 2019
We compared elastic moduli in polar firn derived from diving wave refraction seismic velocity analysis, firn-core density measurements and microstructure modelling based on firn-core data.

Glaciological and Geomorphological Reconnaissance in the Antarctic in 1956 [PDF]

Journal of Glaciology, 1957
AbstractThis paper presents a preliminary account of the glaciological observations made by the Antarctic Expedition of the U.S.S.R. Academy of Sciences in Kaiser Wilhelm II Land, Queen Mary Land and Knox Coast in 1956. The topography of the edge of the ice sheet is described, and the ice regime is discussed, particularly in relation to the existence ...

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]

, 2013
We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability
