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

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.

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.

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 ...

Multidecadal Arctic sea ice thickness and volume derived from ice age [PDF]
The Cryosphere, 2020 Sea ice is a key component of the Arctic climate system, and has impacts on global climate. Ice concentration, thickness, and volume are among the most important Arctic sea ice parameters.

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.

Advanced Engineering Materials, EarlyView., 2023 A novel method for tracking structural changes in gels using widely accessible microcomputed tomography is presented and validated for various hydro‐, alco‐, and aerogels. The core idea of the method is to track positions of micrometer‐sized tracer particles entrapped in the gel and relate them to the density of the gel network.

Evaluation of sea-ice thickness from four reanalyses in the Antarctic Weddell Sea [PDF]
The Cryosphere, 2021 Ocean–sea-ice coupled models constrained by various observations provide different ice thickness estimates in the Antarctic. We evaluate contemporary monthly ice thickness from four reanalyses in the Weddell Sea: the German contribution of the project ...

Sea ice thickness and recent Arctic warming [PDF]
Geophysical Research Letters, 2017 AbstractThe climatic impact of increased Arctic sea ice loss has received growing attention in the last years. However, little focus has been set on the role of sea ice thickness, although it strongly determines surface heat fluxes. Here ensembles of simulations using the EC‐Earth atmospheric model (Integrated Forecast System) are performed and ...
