Simultaneous estimation of wintertime sea ice thickness and snow depth from space-borne freeboard measurements [PDF]

open access: yesThe Cryosphere, 2020
A method of simultaneously estimating snow depth and sea ice thickness using satellite-based freeboard measurements over the Arctic Ocean during winter was proposed.

The sub-ice platelet layer and its influence on freeboard to thickness conversion of Antarctic sea ice [PDF]

open access: yesThe Cryosphere, 2014
This is an investigation to quantify the influence of the sub-ice platelet layer on satellite measurements of total freeboard and their conversion to thickness of Antarctic sea ice. The sub-ice platelet layer forms as a result of the seaward advection of

Basal roughness of the East Antarctic Ice Sheet in relation to flow speed and basal thermal state

open access: yesAnnals of Glaciology, 2020
Basal motion of ice sheets depends in part on the roughness and material properties of the subglacial bed and the occurrence of water. To date, basal motion represents one of the largest uncertainties in ice-flow models. It is that component of the total

Summer sea ice characteristics and morphology in the Pacific Arctic sector as observed during the CHINARE 2010 cruise [PDF]

open access: yesThe Cryosphere, 2013
In the summer of 2010, atmosphere–ice–ocean interaction was studied aboard the icebreaker R/V Xuelong during the Chinese National Arctic Research Expedition (CHINARE), in the sea ice zone of the Pacific Arctic sector between 150° W and 180° W up to 88.5°

Estimating Arctic Sea Ice Thickness with CryoSat-2 Altimetry Data Using the Least Squares Adjustment Method

open access: yesSensors, 2020
Satellite altimeters can be used to derive long-term and large-scale sea ice thickness changes. Sea ice thickness retrieval is based on measurements of freeboard, and the conversion of freeboard to thickness requires knowledge of the snow depth and snow,

Glacier thickness and volume estimation in the Upper Indus Basin using modeling and ground penetrating radar measurements

open access: yesAnnals of Glaciology, 2023
In the Himalaya, ice thickness data are limited, and field measurements are even scarcer. In this study, we employed the GlabTop model to estimate ice reserves in the Jhelum (1.9 ± 0.6 km3) and Drass (2.9 ± 0.9 km3) sub-basins of the Upper Indus Basin ...

Ice thickness, volume and subglacial relief of Djankuat Glacier (Central Caucasus)

open access: yesЛëд и снег, 2015
In this paper we present and discuss results of radio-echo sounding and modelling of ice thickness of the Djankuat Glacier. This glacier is the reference one for the Central Caucasus and was earlier studied comprehensively, but direct ice thickness ...

A sea-ice thickness retrieval model for 1.4 GHz radiometry and application to airborne measurements over low salinity sea-ice [PDF]

open access: yesThe Cryosphere, 2010
In preparation for the European Space Agency's (ESA) Soil Moisture and Ocean Salinity (SMOS) mission, we investigated the potential of L-band (1.4 GHz) radiometry to measure sea-ice thickness.

Measuring thickness of marine ice using IR thermography [PDF]

open access: yesCold Regions Science and Technology, 2019
Abstract There are several challenges to operating in a cold climate. Marine icing is one of them, and its mitigation is vital for marine operations. The presented work is a laboratory-scale setup to measure marine ice thickness. The developed methodology can be applied towards de-/anti-icing setups.

Sea-ice thickness measurement based on the dispersion of ice swell

open access: yesThe Journal of the Acoustical Society of America, 2012
The dispersion of flexural waves propagating in the Arctic sea ice cover is exploited in order to locally measure the ice thickness. The observed dispersion, for waves filtered in the 4–20 s period interval, at up to 4 broad-band seismometers deployed in Spring 2007 near the North Pole, is compared to a parameterized model that accounts for a complex ...
