The role of GPR techniques in determining ice cave properties: Peña Castil ice cave, Picos de Europa [PDF]
, 2016 Producción CientíficaThe structure and ice content of ice caves are poorly understood. Ground penetrating radar (GPR) can provide useful insights but has only rarely been applied to ice caves.

Tracer Measurements in Growing Sea Ice Support Convective Gravity Drainage Parameterizations [PDF]
, 2020 Gravity drainage is the dominant process redistributing solutes in growing sea ice. Modeling gravity drainage is therefore necessary to predict physical and biogeochemical variables in sea ice.

Annual Review of Fluid Mechanics, 2013 We describe the development of mathematical models of ice sheets, focusing on underlying physics and the minimal components that successful models must contain. Our review describes the basic fluid dynamical ice-flow models currently in use; points out numerous poorly understood thermomechanical feedbacks in ice flow; and describes the current, often ...

Modelling last glacial cycle ice dynamics in the Alps
The Cryosphere, 2017 . The European Alps, the cradle of pioneering glacial studies, are one of the regions where geological markers of past glaciations are most abundant and well-studied.

Rapid Basal Channel Growth Beneath Greenland's Longest Floating Ice Shelf
Geophysical Research Letters, 2023 Nioghalvfjerdsfjorden Glacier (N79) is one of the two main outlets for Greenland's largest ice stream, the Northeast Greenland Ice Stream, and is the more stable of the two, with no calving front retreat expected in the near future. Using a novel surface

Impact of runoff temporal distribution on ice dynamics [PDF]
The Cryosphere, 2022 Record highs of meltwater production at the surface of the Greenland ice sheet have been recorded with a high recurrence over the last decades. Those melt seasons with longer durations, larger intensities, or with both increased length and melt intensity

Melt regimes, internal stratigraphy, and flow dynamics of three glaciers in the Alaska Range [PDF]
, 2012 We used ground-penetrating radar (GPR), GPS and glaciochemistry to evaluate melt regimes and ice depths, important variables for mass-balance and ice-volume studies, of Upper Yentna Glacier, Upper Kahiltna Glacier and the Mount Hunter ice divide, Alaska.

Application of Discrete Element Methods to Approximate Sea Ice Dynamics
Journal of Advances in Modeling Earth Systems, 2018 Lagrangian models of sea ice dynamics have several advantages over Eulerian continuum models. Spatial discretization on the ice floe scale is natural for Lagrangian models and offers exact solutions for mechanical nonlinearities with arbitrary sea ice ...
