How we know Antarctica is rapidly losing more ice
Satellite observations of the Antarctic surface since the 1990s, coupled with geophysical surveys of the flow and form of its giant ice sheet, have revealed accelerating loss of ice to the oceans. This, coupled with a reduction in floating sea ice surrounding the continent and the occurrence of unprecedented heatwaves, point to a continent being changed irreversibly by fossil-fuel burning and the global heating that results. A changing Antarctic …

On thick ice
This paper focuses on the role played by scientific internationalism in Antarctica during the two decades that followed the signing and ratification of the Antarctic Treaty in 1961. The paper shows that the Treaty was a response to the threat to the ‘free world’ represented by the installation of Soviet bases in Antarctica. Scientific internationalism was used as a diplomatic weapon to respond to that threat. In the 1960s, the development of inte…
Data in Antarctic Science and Politics
The internationalization of Antarctica as a continent for science with the Antarctic Treaty (1961) was heralded as bringing about international cooperation and the free exchange of data. However, both national rivalry and proprietorship of data, in varying degrees, remained integral to Antarctic science and politics throughout the 20th century. This paper considers two large field-surveys in Antarctica: first, an aerial photographic survey carrie…
The IGY and the ice sheet
Accidents and opportunities
This paper explores the history of radio echo-sounding (RES), a technique of glaciological surveying that from the late 1960s has been used to examine Antarctica's sub-glacial morphology. Although the origins of RES can be traced back to two accidental findings, its development relied upon the establishment of new geopolitical conditions, which in the 1960s typified Antarctica as a continent devoted to scientific exploration. These conditions ext…
Late Quaternary ice sheet history of northern Eurasia
Evidence for a large surface ablation zone in central East Antarctica during the last Ice Age
Internal isochronous ice sheet layers, recorded by airborne ice-penetrating radar, were measured along an ice flowline across a large (>1 km high) subglacial hill in the foreground of the Transantarctic Mountains. The layers, dated through an existing stratigraphic link with the Vostok ice core, converge with the ice surface as ice flows over the hill without noticeable change to their separation with each other or the ice base. A two-dimensional…
An International Plan for Antarctic Subglacial Lake Exploration
Discovery of at least 100 subglacial lakes beneath the vast East Antarctic Ice Sheet has focused international attention on the challenges presented by the way we conduct science in such unique and inhospitable settings in an atmosphere of increasingly stringent environmental concerns. Exploration of subglacial environments will require careful and detailed planning, organization, and international cooperation. To this end, the Scientific Committ…
Which Are the Most Suitable Antarctic Subglacial Lakes for Exploration
In 1996 Lake Vostok was brought to the attention of the scientific community, and the world'smedia, as a potential habitat for unique life isolated for millions of years (Kapitsa et al., 1996), and an inventory of over 70 other lakes beneath the Antarctic ice sheet was published (Siegert et al., 1996). Since then, plans have been forming as to how water and sediments may be sampled from these sub-ice environments. To guide the planning of such wo…
Late Weichselian Glaciation of the Russian High Arctic
A numerical ice-sheet model was used to reconstruct the Late Weichselian glaciation of the Eurasian High Arctic, between Franz Josef Land and Severnaya Zemlya. An ice sheet was developed over the entire Eurasian High Arctic so that ice flow from the central Barents and Kara seas toward the northern Russian Arctic could be accounted for. An inverse approach to modeling was utilized, where ice-sheet results were forced to be compatible with geologi…
Numerical Modeling of the Late Weichselian Svalbard-Barents Sea Ice Sheet
Previous reconstructions of the ice cover of the Svalbard-Barents Sea region during the late Weichselian have ranged from small ice masses on Svalbard to complete inundation of the Barents Shelf region by an ice sheet several kilometers thick. We have used a time-dependent finite-difference numerical model to undertake a new glaciological reconstruction for the Svalbard-Barents Sea Ice Sheet over the last 30,000 yr. The numerical model requires e…
