Interannual variability in Transpolar Drift summer sea ice thickness and potential impact of Atlantification [PDF]
The Cryosphere, 2021 Changes in Arctic sea ice thickness are the result of complex interactions of the dynamic and variable ice cover with atmosphere and ocean. Most of the sea ice exiting the Arctic Ocean does so through Fram Strait, which is why long-term measurements of ...

MeasureIce: accessible on-the-fly measurement of ice thickness in cryo-electron microscopy [PDF]
Communications Biology, 2021 Abstract Ice thickness is arguably one of the most important factors limiting the resolution of protein structures determined by cryo-electron microscopy (cryo-EM). The amorphous atomic structure of the ice that stabilizes and protects biological samples in cryo-EM grids also imprints some additional noise in cryo-EM images.

Winter accumulation in the percolation zone of Greenland measured by airborne radar altimeter [PDF]
, 2007 We here determine the surface elevation and the winter snow accumulation rate along a profile in the percolation zone of the Greenland Ice Sheet from data collected with ESA's Airborne SAR/Interferometric Radar Altimeter System (ASIRAS) in spring 2004 ...

Potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets [PDF]
, 2013 We use the Shreve hydraulic potential equation as a simplified approach to investigate potential subglacial lake locations and meltwater drainage pathways beneath the Antarctic and Greenland ice sheets. We validate the method by demonstrating its ability

Antarctic ice shelf thickness change from multimission lidar mapping [PDF]
The Cryosphere, 2019 We calculate rates of ice thickness change and bottom melt for ice shelves in West Antarctica and the Antarctic Peninsula from a combination of elevation measurements from NASA–CECS Antarctic ice mapping campaigns and NASA Operation IceBridge corrected ...

Journal of Glaciology, 2021 Knowledge of glacier volume is crucial for ice flow modelling and predicting the impacts of climate change on glaciers. Rugged terrain, harsh weather conditions and logistic costs limit field-based ice thickness observations in the Himalaya.

Near-margin ice thickness and subglacial water routing, Leverett Glacier, Greenland
Arctic, Antarctic, and Alpine Research, 2018 Ice thickness measurements near the margin of the Greenland Ice Sheet (GrIS) are relatively sparse, presenting issues for modeling ice-flow dynamics, ice-sheet change, and subglacial hydrology.

Application of a two-step approach for mapping ice thickness to various glacier types on Svalbard [PDF]
The Cryosphere, 2017 The basal topography is largely unknown beneath most glaciers and ice caps, and many attempts have been made to estimate a thickness field from other more accessible information at the surface.
