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

open access: yesSensors (Basel), 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,

Arctic ice cover, ice thickness and tipping points. [PDF]

open access: yesAmbio, 2012
We summarize the latest results on the rapid changes that are occurring to Arctic sea ice thickness and extent, the reasons for them, and the methods being used to monitor the changing ice thickness. Arctic sea ice extent had been shrinking at a relatively modest rate of 3-4% per decade (annually averaged) but after 1996 this speeded up to 10% per ...

Estimating lake ice thickness in Central Ontario. [PDF]

open access: yesPLoS One, 2018
Lakes are a key geographical feature in Canada and have an impact on the regional climate. In the winter, they are important for recreational activities such as snowmobiling and ice fishing and act as part of an important supply route for northern communities. The ability to accurately report lake ice characteristics such as thickness is vital, however,

Ice thickness and bed topography of Jostedalsbreen ice cap, Norway [PDF]

open access: yesEarth System Science Data
We present an extensive dataset of ice thickness measurements from Jostedalsbreen ice cap, mainland Europe's largest glacier. The dataset consists of more than 351 000 point values of ice thickness distributed along ∼ 1100 km profile segments that cover ...

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. [PDF]

open access: yesSensors (Basel), 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.

Assimilating CryoSat-2 freeboard to improve Arctic sea ice thickness estimates [PDF]

open access: yesThe Cryosphere, 2023
In this study, a new method to assimilate freeboard (FB) derived from satellite radar altimetry is presented with the goal of improving the initial state of sea ice thickness predictions in the Arctic.

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.

Research on the Improvement Method of OPGW Ground Uneven Icing Calculation Model under Micro-terrain

open access: yesZhongguo dianli, 2023
At present, there are many studies on the calculation model of equivalent ice thickness of overhead line under uniform ice cover, but there is a lack of research on OPGW ground ice covering with large cross-section and large unit length weight ...

Estimation of River Ice Thickness in the Shisifenzi Reach of the Yellow River With Remote Sensing and Air Temperature Data

open access: yesIEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2023
River ice is an important part of the cryosphere, and effective monitoring of ice thickness information is essential for river ice research. The task of preventing and controlling winter ice damage in the Yellow River is severe, and it is significant to ...
