Regime shift in Arctic Ocean sea ice thickness. [PDF]

Nature, 2023
AbstractManifestations of climate change are often shown as gradual changes in physical or biogeochemical properties1. Components of the climate system, however, can show stepwise shifts from one regime to another, as a nonlinear response of the system to a changing forcing2.

Sea Ice Thickness in the Western Ross Sea [PDF]

Geophysical Research Letters, 2021
AbstractUsing airborne measurements, we provide a first direct glimpse of the sea ice thickness distribution in the western Ross Sea, Antarctica, where the distinguishing sea ice process is the regular occurrence of the Ross Sea, McMurdo Sound, and Terra Nova Bay polynyas.

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 ...

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

The 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.

Sea ice thickness and production in Weddell Sea polynyas

, 2022
<p>Open-ocean and coastal polynyas, the result of high-latitude atmosphere-ocean circulation interannual variability, alter the local air-ocean heat exchange and sea ice production. Yet, the role of the ocean, especially its thermal flux, is rarely discussed.

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.

Feasibility of retrieving Arctic sea ice thickness from the Chinese HY-2B Ku-band radar altimeter [PDF]

The Cryosphere, 2023
With the continuous development of the China ocean dynamic environment satellite series (Haiyang-2, HY-2), it is urgent to explore the potential application of HY-2B in Arctic sea ice thickness retrievals.

Arctic sea ice variation in the Northwest Passage in 1979–2017 and its response to surface thermodynamics factors

Advances in Climate Change Research, 2021
Sea ice conditions in the Canadian Arctic Archipelago (CAA) play a key role in the navigation of the Northwest Passage (NWP). Limited by observed sea ice thickness data, the research of temporal and spatial variation of sea ice in the NWP is insufficient.
