• Modification of bedrock surfaces by glacial abrasion and quarrying: Evidence from North Wales 

      Glasser, Neil F.; Roman, Matej; Holt, Tom O.; Žebre, Manja; Patton, Henry; Hubbard, Alun Lloyd (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-05-30)
      Abrasion and quarrying are significant processes of subglacial erosion for ice masses in direct contact with hard substrates, yet their relative efficacy and spatio-temporal variability is unclear. Here, we investigate the glacial impact of these processes on a 70 m by 60 m bedrock surface at Moel Ysgyfarnogod in the Rhinog Mountains, Wales, using a combination of high-resolution digital photographs, ...
    • A steady-state model reconstruction of the patagonian ice sheet during the last glacial maximum 

      Wolff, Ingo W.; Glasser, Neil F.; Harrison, Stephan; Wood, Joanne Laura; Hubbard, Alun (Journal article; Tidsskriftartikkel; Peer reviewed, 2023-07-17)
      During the Last Glacial Maximum (LGM), the Patagonian Ice Sheet (PIS) was the largest Quaternary ice mass in the Southern Hemisphere outside of Antarctica. Although the margins of the LGM ice sheet are now well established through end-moraine mapping and dating, apart from a few modelling and empirical studies, there remains a lack of constraint on its thickness and three-dimensional configuration. ...
    • Supraglacial ponds regulate runoff from Himalayan debris-covered glaciers 

      Irvine-Fynn, Tristram D.L.; Porter, Philip R.; Rowan, Ann V.; Quincey, Duncan J.; Gibson, Morgan J.; Bridge, Jonathan W.; Watson, C. Scott; Hubbard, Alun Lloyd; Glasser, Neil F. (Journal article; Tidsskriftartikkel; Peer reviewed, 2017-11-29)
      Meltwater and runoff from glaciers in High Mountain Asia is a vital freshwater resource for one-fifth of the Earth’s population. Between 13% and 36% of the region’s glacierized areas exhibit surface debris cover and associated supraglacial ponds whose hydrological buffering roles remain unconstrained. We present a high-resolution meltwater hydrograph from the extensively debris-covered Khumbu ...
