Radar sounding is a powerful geophysical approach for characterizing the subsurface
conditions of terrestrial and planetary ice masses at local to global scales. As a result, a wide …

A growing network of ice cores reveals the past 800,000 years of Antarctic climate and
atmospheric composition. The data show tight links among greenhouse gases, aerosols and …

Over the past eight hundred thousand years, glacial–interglacial cycles oscillated with a
period of one hundred thousand years ('100k world'). Ice core and ocean sediment data …

The past provides evidence of abrupt climate shifts and changes in the frequency of climate
and weather extremes. We explore the nonlinear response to orbital forcing and then …

Several decades of ice‐penetrating radar surveys of the Greenland and Antarctic ice sheets
have observed numerous widespread internal reflections. Analysis of this radiostratigraphy …

Antarctic geothermal heat flow (GHF) affects the temperature of the ice sheet, determining its
ability to slide and internally deform, as well as the behaviour of the continental crust …

Finding suitable potential sites for an undisturbed record of million-year old ice in Antarctica
requires slow-moving ice (preferably an ice divide) and basal conditions that are not …

Gravity surveying is challenging in Antarctica because of its hostile environment and
inaccessibility. Nevertheless, many ground‐based, airborne, and shipborne gravity …

Stable water isotope records from Antarctica are key for our understanding of Quaternary
climate variations. However, the exact quantitative interpretation of these important climate …

For about 50 yr, ice cores have provided a wealth of information about past climatic and
environmental changes. Ice cores from Greenland, Antarctica and other glacier-covered …
