Controls on long-term denudation rate of carbonate terrains in the Eastern Mediterranean
Quantifying denudation rates under different climatic and tectonic settings is fundamental to
understanding landscape evolution. Carbonate rocks may respond differently to climatic and …

Patterns of spatio-temporal paraglacial response in the Antarctic Peninsula region and associated ecological implications
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 …

60 million years of glaciation in the Transantarctic Mountains
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 …

Moraine crest or slope: An analysis of the effects of boulder position on cosmogenic exposure age
Terrestrial cosmogenic nuclide dating of ice-marginal moraines can provide unique insights
into Quaternary glacial history. However, pre-and post-depositional exposure histories of …

[HTML][HTML] Antarctic permafrost processes and antiphase dynamics of cold-based glaciers in the McMurdo Dry Valleys inferred from Be and Al cosmogenic nuclides
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 …

Carbonate and silicate intercomparison materials for cosmogenic 36Cl measurements
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 …

Glacial trimlines to identify former ice margins and subglacial thermal boundaries: A review and classification scheme for trimline expression
CM Rootes, CD Clark - Earth-Science Reviews, 2020 - Elsevier
Reconstructions of former ice sheets and glaciers provide important palaeoglaciological
information about their behaviour in response to climate changes. Glacial trimlines record …

[HTML][HTML] Blue-ice moraines formation in the Heritage Range, West Antarctica: Implications for ice sheet history and climate reconstruction
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 …

Salt deliquescence along boulder cracks in the Antarctic Dry Valleys: An overlooked source of moisture for rock weathering processes
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 …
