Arctic Snow Depth, Ice Thickness, and Volume From ICESat‐2 and CryoSat‐2: 2018–2021

Geophysical Research Letters, 2022
Using ICESat‐2 and CryoSat‐2 freeboards, we examine the variability of monthly Arctic sea ice snow depth, thickness and volume between October 2018 and April 2021. For the 3 years, satellite‐derived estimates captured a decrease in mean April snow depth (

Thermodynamic and dynamic contributions to seasonal Arctic sea ice thickness distributions from airborne observations

Elementa: Science of the Anthropocene, 2022
Sea ice thickness is a key parameter in the polar climate and ecosystem. Thermodynamic and dynamic processes alter the sea ice thickness. The Multidisciplinary drifting Observatory for the Study of Arctic Climate (MOSAiC) expedition provided a unique ...

Combining a New Parameterization Scheme of Oceanic Heat Flux with Thickness Assimilation to Improve Sea Ice Forecast Accuracy in Liaodong Bay

Journal of Marine Science and Engineering, 2023
Liaodong Bay is one of the lowest latitude areas with seasonal sea ice cover in the Northern Hemisphere. Sea ice forecasting faces challenges in accuracy due to its low thickness.

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

Journal 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.

Transition to marine ice cliff instability controlled by ice thickness gradients and velocity

Science, 2021
Cliff collapse Tall ice cliffs at the edges of ice sheets can collapse under their own weight in spectacular fashion, a process that can considerably hasten ice sheet mass loss. Bassis et al.

A long-term proxy for sea ice thickness in the Canadian Arctic: 1996–2020 [PDF]

The Cryosphere, 2023
This study presents a long-term winter sea ice thickness proxy product for the Canadian Arctic based on a random forest regression model – applied to ice charts and scatterometer data, trained on CryoSat-2 observations, and applying an ice type–sea ice ...

Probabilistic Forecasts of Arctic Sea Ice Thickness [PDF]

Journal of Agricultural, Biological and Environmental Statistics, 2021
AbstractIn recent decades, warming temperatures have caused sharp reductions in the volume of sea ice in the Arctic Ocean. Predicting changes in Arctic sea ice thickness is vital in a changing Arctic for making decisions about shipping and resource management in the region.
