Subglacial lakes and hydrology across the Ellsworth Subglacial Highlands, West Antarctica (2020)
Journal Article
Napoleoni, F., Jamieson, S., Ross, N., Bentley, M., Rivera, A., Smith, A., …Vaughan, D. (2020). Subglacial lakes and hydrology across the Ellsworth Subglacial Highlands, West Antarctica. The Cryosphere, 14, 4507-4524. https://doi.org/10.5194/tc-14-4507-2020

Subglacial water plays an important role in ice sheet dynamics and stability. Subglacial lakes are often located at the onset of ice streams and have been hypothesised to enhance ice flow downstream by lubricating the ice– bed interface. The most rec...

Long-term increase in Antarctic Ice Sheet vulnerability driven by bed topography evolution (2020)
Journal Article
Paxman, G., Gasson, E., Jamieson, S., Bentley, M., & Ferraccioli, F. (2020). Long-term increase in Antarctic Ice Sheet vulnerability driven by bed topography evolution. Geophysical Research Letters, 47(20), Article e2020GL090003. https://doi.org/10.1029/2020gl090003

Ice sheet behavior is strongly influenced by the bed topography. However, the effect of the progressive temporal evolution of Antarctica's subglacial landscape on the sensitivity of the Antarctic Ice Sheet (AIS) to climatic and oceanic change has yet...

A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID) (2020)
Journal Article
Timoney, R., Worrall, K., Firstbrook, D., Harkness, P., Rix, J., Ashurst, D., …Bentley, M. J. (2020). A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID). Cold Regions Science and Technology, 177, Article 103113. https://doi.org/10.1016/j.coldregions.2020.103113

The paleoclimate community has an interest in distributed subglacial bedrock sampling but, while capable drill systems do exist, they are often incompatible with Twin Otter logistics. To address this issue, a design built on the existing low footprin... Read More about A low resource subglacial bedrock sampler: The percussive rapid access isotope drill (P-RAID).
