Megaflutes in the Menteith Hills, central Scotland
‘Flutings’ or ‘flutes’ are elongated, flow-parallel subglacial bedforms associated with relatively fast flowing glaciers. Analysis of recently acquired high-resolution (50 cm) LiDAR data has identified the presence of large, very low-relief flutings on the Menteith Hills in Central Scotland. These subtle landforms, up to 1 km in length and 10s of metres wide, are interpreted as ‘megaflutes’, falling in between the accepted definition of flutes an…
Surging glaciers in Scotland
Glacier surges are cyclic oscillations of velocity and mass resulting from internal dynamic instabilities. For surge-type glaciers, cycles of advance and retreat are decoupled from climate forcing, so it is important to consider the possibility that former glaciers may have been surge-type when making climatic inferences from their dimensions and chronologies. In this paper, climatic and glacier geometric data are used to show that Scotland was l…
West Antarctic ice sheet and CO 2 greenhouse effect: A threat of disaster
Over 40 years ago, the glaciologist John Mercer warned that parts of the West Antarctic Ice Sheet were at risk of collapse due to the CO2 greenhouse effect. Mercer recognised the unique vulnerability of ice sheets resting on beds far below sea level (marine-based ice sheets), where an initial warming signal can initiate irreversible retreat. In this paper, we review recent work on evidence for ice sheet collapse in warmer periods of the recent ge…
Reconstruction of equilibrium-line altitudes for tropical and sub-tropical glaciers
Equilibrium-line altitudes of the Last Glacial Maximum for the Himalaya and Tibet: An assessment and evaluation of results
Himalayan glacial sedimentary environments: A framework for reconstructing and dating the former extent of glaciers in high mountains
Glacial Sediment–Landform Associations and Paleoclimate during the Last Glaciation, Strait of Magellan, Chile
Glacial sediments and landforms preserved beside the Strait of Magellan record repeated advances of an outlet of the Patagonian Icefield during and following the last glacial maximum (LGM; ∼25,000–14,000 14 C yr B.P.). Ice-marginal landform assemblages consist of thrust moraine complexes, kame and kettle topography, and lateral meltwater channels, very similar to those found at the margins of modern subpolar glaciers. Taken together with other fo…
Mass balance and equilibrium-line altitudes of glaciers in high-mountain environments
The role of the Indian summer monsoon and the mid-latitude westerlies in Himalayan glaciation: Review and speculative discussion
New dates for late Quaternary glaciations in the Himalayas show that, during the last glacial cycle, glaciations were not synchronous throughout the region. Rather, in some areas glaciers reached their maxima at the global glacial maximum of c. 18–20 ka bp , whereas in others glaciers were most extensive at c. 60–30 ka bp . Comparison of these data with palaeoclimatic records from adjacent regions suggest that, on millennial timescales, Himalayan…
