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

open access: yesSensors, 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,

New insight from CryoSat-2 sea ice thickness for sea ice modelling [PDF]

open access: yesThe 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 ...

Dependence of Sea Ice Yield-Curve Shape on Ice Thickness [PDF]

open access: bronze, 2004
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.

Improving the spatial distribution of modeled Arctic sea ice thickness [PDF]

open access: bronze, 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

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]

open access: yesSensors, 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.

Assimilation of sea-ice concentration in a global climate model – physical and statistical aspects [PDF]

open access: yesOcean Science, 2013
We investigate the initialisation of Northern Hemisphere sea ice in the global climate model ECHAM5/MPI-OM by assimilating sea-ice concentration data. The analysis updates for concentration are given by Newtonian relaxation, and we discuss different ways

Relating the Age of Arctic Sea Ice to its Thickness, as Measured during NASA’s ICESat and IceBridge Campaigns [PDF]

open access: goldRemote Sensing, 2016
Recent satellite observations yield estimates of the distribution of sea ice thickness across the entire Arctic Ocean. While these sensors were only placed in operation within the last few years, information from other sensors may assist us with ...

Near-real-time Arctic sea ice thickness and volume from CryoSat-2 [PDF]

open access: yesThe Cryosphere, 2016
Timely observations of sea ice thickness help us to understand the Arctic climate, and have the potential to support seasonal forecasts and operational activities in the polar regions.

The sub-ice platelet layer and its influence on freeboard to thickness conversion of Antarctic sea ice [PDF]

open access: greenThe Cryosphere, 2014
This is an investigation to quantify the influence of the sub-ice platelet layer on satellite measurements of total freeboard and their conversion to thickness of Antarctic sea ice. The sub-ice platelet layer forms as a result of the seaward advection of

A weekly Arctic sea-ice thickness data record from merged CryoSat-2 and SMOS satellite data [PDF]

open access: yesThe Cryosphere, 2017
Sea-ice thickness on a global scale is derived from different satellite sensors using independent retrieval methods. Due to the sensor and orbit characteristics, such satellite retrievals differ in spatial and temporal resolution as well as in the ...
