    • Morphology and evolution of supraglacial hummocks on debris-covered Himalayan glaciers 

      Bartlett, Oliver T.; Ng, Felix S.L.; Rowan, Ann V. (2021-03-15)
      Thick supraglacial debris layers often have an undulating, hummocky topography that influences the lateral transport of debris and meltwater and provides basins for supraglacial ponds. The role of ablation and other processes ...

    • Seasonally stable temperature gradients through supraglacial debris in the Everest region of Nepal, Central Himalaya 

      Rowan, Ann V.; Nicholson, Lindsey I.; Quincey, Duncan J.; Gibson, Morgan J.; Irvine-Fynn, Tristram D.L.; Watson, C. Scott; Wagnon, Patrick; Rounce, David R.; Thompson, Sarah S.; Porter, Philip R.; Glasser, Neil F. (2020-12-03)
      Rock debris covers about 30% of glacier ablation areas in the Central Himalaya and modifies the impact of atmospheric conditions on mass balance. The thermal properties of supraglacial debris are diurnally variable but ...

    • Supraglacial ponds regulate runoff from Himalayan debris-covered glaciers. 

      Irvine-fynn, Tristam D. L.; Porter, Philip; Rowan, Ann V.; Quincey, Duncan J.; Gibson, Morgan J.; Bridge, Jonathan W.; Watson, C. Scott; Hubbard, Alun; Glasser, Neil F. (2017-12-16)
      Meltwater and runoff from 1 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 ...

    • The sustainability of water resources in the High Mountain Asia in the context of recent and future glacier change. 

      Rowan, Ann V.; Quincey, Duncan J.; Gibson, Morgan J.; Glasser, Neil F.; Westoby, Matthew J.; Irvine-Fynn, Tristam D. L.; Porter, Philip; Hambrey, Michael J. (2017-11-01)
      High Mountain Asia contains the largest volume of glacier ice outside the Polar regions, and contain the headwaters of some of the largest rivers in central Asia. These glaciers are losing mass at a mean rate of between ...
