Quantifying denudation rates under different climatic and tectonic settings is fundamental to
understanding landscape evolution. Carbonate rocks may respond differently to climatic and …

Abstract The Antarctic Peninsula (AP) constitutes the warmest region of Antarctica, although
98% of the surface is still covered by glaciers. The region shows contrasting geographic and …

The Antarctic continent reached its current polar location~ 83 Ma and became shrouded by
ice sheets~ 34 Ma, coincident with dramatic global cooling at the Eocene-Oligocene …

We collected a debris-rich ice core from a buried ice mass in Ong Valley, located in the
Transantarctic Mountains in Antarctica. We measured cosmogenic nuclide concentrations in …

Terrestrial cosmogenic nuclide dating of ice-marginal moraines can provide unique insights
into Quaternary glacial history. However, pre-and post-depositional exposure histories of …

Soil and sediment mixing and associated permafrost processes are not widely studied or
understood in the McMurdo Dry Valleys of Antarctica. In this study, we investigate the …

Two natural mineral separates, labeled CoCal-N and CoFsp-N, have been prepared to
serve as intercomparison material (ICM) for in situ-produced cosmogenic 36 Cl and natural …

Reconstructions of former ice sheets and glaciers provide important palaeoglaciological
information about their behaviour in response to climate changes. Glacial trimlines record …

Blue ice is found in areas of Antarctica where katabatic winds, focussed by steep surface
slopes or by topography around nunataks, cause enhanced surface ablation. This process …

Cracking is a primary rock-weathering mechanism in arid environments, where dry
conditions typically limit the efficacy of water-driven weathering processes. Here, we present …
