Dependence of Sea Ice Yield-Curve Shape on Ice Thickness [PDF]
Journal of Physical Oceanography, 2004 Abstract In this note, the authors discuss the contribution that frictional sliding of ice floes (or floe aggregates) past each other and pressure ridging make to the plastic yield curve of sea ice. Using results from a previous study that explicitly modeled the amount of sliding and ridging that occurs for a given global strain rate, it

New insight from CryoSat-2 sea ice thickness for sea ice modelling [PDF]
The Cryosphere, 2019 Estimates of Arctic sea ice thickness have been available from the CryoSat-2 (CS2) radar altimetry mission during ice growth seasons since 2010. We derive the sub-grid-scale ice thickness distribution (ITD) with respect to five ice thickness categories ...

Summertime sea-ice prediction in the Weddell Sea improved by sea-ice thickness initialization. [PDF]
Sci Rep, 2021 AbstractSkillful sea-ice prediction in the Antarctic Ocean remains a big challenge due to paucity of sea-ice observations and insufficient representation of sea-ice processes in climate models. Using a coupled general circulation model, this study demonstrates skillful prediction of the summertime sea-ice concentration (SIC) in the Weddell Sea with ...

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

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 as a stochastic process [PDF]
Journal of Geophysical Research: Oceans, 2000 Observed probability distributions of sea ice thickness are approximately exponential for thick ice. An explanation is given on the basis of simple representations of the thermal and mechanical processes. The argument predicts that the e‐folding scale for the exponential is proportional to the thermal equilibrium thickness.

Sea-ice thickness and roughness in the Ross Sea, Antarctica [PDF]
Annals of Glaciology, 2001 AbstractSea-ice thickness and roughness data collected on three cruises in the Ross Sea, Antarctica, showed interseasonal, regional and interannual variability. Variability was reduced to season, or age of ice floe, when sea-ice roughness values from around Antarctica were compared.

Improving the spatial distribution of modeled Arctic sea ice thickness [PDF]
, 2005 The spatial distribution of ice thickness/draft in the Arctic Ocean is examined using a sea ice model. A comparison of model predictions with submarine observations of sea ice draft made during cruises between 1987 and 1997 reveals that the model has the

Thickness distribution of Antarctic sea ice [PDF]
Journal of Geophysical Research: Oceans, 2008 Ship‐based observations are used to describe regional and seasonal changes in the thickness distribution and characteristics of sea ice and snow cover thickness around Antarctica. The data set comprises 23,373 observations collected over more than 2 decades of activity and has been compiled as part of the Scientific Committee on Antarctic Research ...

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]
Sensors, 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.
