Discrimination Algorithm and Procedure of Snow Depth and Sea Ice Thickness Determination Using Measurements of the Vertical Ice Temperature Profile by the Ice-Tethered Buoys

open access: yesSensors, 2018
Snow depth and sea ice thickness in the Polar Regions are significant indicators of climate change and have been measured over several decades by ice-tethered buoys.

Antarctic ice shelf thickness change from multimission lidar mapping [PDF]

open access: yesThe 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 ...

Application of a two-step approach for mapping ice thickness to various glacier types on Svalbard [PDF]

open access: yesThe 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.

Efficiency of artificial neural networks for glacier ice-thickness estimation: a case study in western Himalaya, India

open access: yesJournal 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.

Measuring sea ice through thick and thin [PDF]

open access: yesScience, 2014
Climate Change Sea ice in the Arctic's Fram Straight is only half as thick as it was a decade ago, Renner and colleagues report. Measuring ice both at the surface and from the air with an instrument towed below a helicopter, they found that the ice in that region thinned by more than 50% between 2003 and 2012.

Near-margin ice thickness and subglacial water routing, Leverett Glacier, Greenland

open access: yesArctic, 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.

Assessment of contemporary satellite sea ice thickness products for Arctic sea ice [PDF]

open access: yesThe Cryosphere, 2019
Advances in remote sensing of sea ice over the past two decades have resulted in a wide variety of satellite-derived sea ice thickness data products becoming publicly available.

The Influence of Snow and Ice Albedo towards Improved Lake Ice Simulations

open access: yesHydrology, 2021
Lake ice models are a vital tool for studying the response of ice-covered lakes to changing climates throughout the world. The Canadian Lake Ice Model (CLIMo) is a one-dimensional freshwater ice cover model that simulates Arctic and sub-Arctic lake ice ...

Radiometric analysis of digitized Z-scope records in archival radar sounding film

open access: yesJournal of Glaciology, 2022
The earliest airborne geophysical campaigns over Antarctica and Greenland in the 1960s and 1970s collected ice penetrating radar data on 35 mm optical film. Early subglacial topographic and englacial stratigraphic analyses of these data were foundational

Optimization of a sea ice model using basinwide observations of Arctic sea ice thickness, extent, and velocity [PDF]

open access: yes, 2006
A stand-alone sea ice model is tuned and validated using satellite-derived, basinwide observations of sea ice thickness, extent, and velocity from the years 1993 to 2001. This is the first time that basin-scale measurements of sea ice thickness have been
