Sea-ice thickness variability in Storfjorden, Svalbard [PDF]
Annals of Glaciology, 2011 AbstractResults from electromagnetic induction surveys of sea-ice thickness in Storfjorden, Svalbard, reveal large interannual ice-thickness variations in a region which is typically characterized by a reoccurring polynya. the surveys were performed in March 2003, May 2006 and March 2007 with helicopter- and ship-based sensors.

Contributions of Ice Thickness to the Atmospheric Response From Projected Arctic Sea Ice Loss
Geophysical Research Letters, 2018 A large ensemble of simulations from a high‐top atmospheric general circulation model are conducted to compare the atmospheric responses from loss of Arctic sea ice thickness and sea ice concentration.

IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing, 2020 Uncertainty in snow properties impacts the accuracy of Arctic sea ice thickness estimates from radar altimetry. On first-year sea ice (FYI), spatiotemporal variations in snow properties can cause the Ku-band main radar scattering horizon to appear above ...

Sea-ice evaluation of NEMO-Nordic 1.0: a NEMO–LIM3.6-based ocean–sea-ice model setup for the North Sea and Baltic Sea [PDF]
Geoscientific Model Development, 2017 The Baltic Sea is a seasonally ice-covered marginal sea in northern Europe with intense wintertime ship traffic and a sensitive ecosystem. Understanding and modeling the evolution of the sea-ice pack is important for climate effect studies and ...

The impact of snow depth, snow density and ice density on sea ice thickness retrieval from satellite radar altimetry: results from the ESA-CCI Sea Ice ECV Project Round Robin Exercise [PDF]
The Cryosphere, 2015 We assess different methods and input parameters, namely snow depth, snow density and ice density, used in freeboard-to-thickness conversion of Arctic sea ice. This conversion is an important part of sea ice thickness retrieval from spaceborne altimetry.

Seasonal Evolution of the Arctic Sea Ice Thickness Distribution
Journal of Geophysical Research: Oceans, 2023 AbstractThe Thorndike et al. (1975, https://doi.org/10.1029/jc080i033p04501) theory of the ice thickness distribution, g(h), treats the dynamic and thermodynamic aggregate properties of the ice pack in a novel and physically self‐consistent manner.

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.

A New Perspective on Four Decades of Changes in Arctic Sea Ice from Satellite Observations
Remote Sensing, 2022 Arctic sea ice characteristics have been changing rapidly and significantly in the last few decades. Using a long-term time series of sea ice products from satellite observations—the extended AVHRR Polar Pathfinder (APP-x)—trends in sea ice concentration,

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

On the timescales and length scales of the Arctic sea ice thickness anomalies: a study based on 14 reanalyses [PDF]
The Cryosphere, 2019 The ocean–sea ice reanalyses are one of the main sources of Arctic sea ice thickness data both in terms of spatial and temporal resolution, since observations are still sparse in time and space.
