A comparison of contemporaneous airborne altimetry and ice-thickness measurements of Antarctic ice shelves

open access: yesJournal of Glaciology, 2023
Estimates of ice shelf mass loss are typically based on surface height measurements, assuming hydrostatic equilibrium and estimated firn thickness.

Measuring sea ice thickness with the LOZA georadar [PDF]

open access: yesRussian Journal of Earth Sciences, 2021
This article documents the use of portable georadar for measuring the thickness of sea ice. This device was developed to replace the method for measuring ice thickness by drilling ice holes.

Measuring and inferring the ice thickness distribution of four glaciers in the Tien Shan, Kyrgyzstan

open access: yesJournal of Glaciology, 2021
Glaciers in the Tien Shan mountains contribute considerably to the fresh water used for irrigation, households and energy supply in the dry lowland areas of Kyrgyzstan and its neighbouring countries. To date, reconstructions of the current ice volume and

Ice volume distribution and implications on runoff projections in a glacierized catchment [PDF]

open access: yesHydrology and Earth System Sciences, 2012
A dense network of helicopter-based ground-penetrating radar (GPR) measurements was used to determine the ice-thickness distribution in the Mauvoisin region.

The relation between sea ice thickness and freeboard in the Arctic [PDF]

open access: yesThe Cryosphere, 2010
Retrieval of Arctic sea ice thickness from CryoSat-2 radar altimeter freeboard data requires observational data to verify the relation between these two variables.

On the errors involved in ice-thickness estimates I: ground-penetrating radar measurement errors [PDF]

open access: yesJournal of Glaciology, 2016
This is the first (Paper I) of three companion papers focused respectively, on the estimates of the errors in ice thickness retrieved from pulsed ground-penetrating radar (GPR) data, on how to estimate the errors at the grid points of an ice-thickness ...

Near-real-time Arctic sea ice thickness and volume from CryoSat-2 [PDF]

open access: yesThe Cryosphere, 2016
Timely observations of sea ice thickness help us to understand the Arctic climate, and have the potential to support seasonal forecasts and operational activities in the polar regions.

Brief communication: Measuring and modelling the ice thickness of the Grigoriev ice cap (Kyrgyzstan) and comparison with global datasets [PDF]

open access: yesThe Cryosphere, 2023
An accurate ice thickness distribution is crucial for correct projections of the future state of an ice mass. However, measuring the ice thickness with an in situ system is time-consuming and not scalable.

Review of methods and main results of sea ice thickness measurements in the Arctic

open access: yesРоссийская Арктика, 2021
Review of main methods of sea ice thickness measurements and results of published researches about climate and interannual variability of this parameter in the Arctic Basin and in the Arctic Seas are presented. Following methods of thickness measurements

Retrieval and parameterisation of sea-ice bulk density from airborne multi-sensor measurements [PDF]

open access: yesThe Cryosphere, 2022
Knowledge of sea-ice thickness and volume depends on freeboard observations from satellite altimeters and in turn on information of snow mass and sea-ice density required for the freeboard-to-thickness conversion.
