Assessment of contemporary satellite sea ice thickness products for Arctic sea ice [PDF]
The Cryosphere, 2018 Abstract. Advances in remote sensing of sea ice over the past two decades have resulted in a wide variety of satellite-derived sea ice thickness data products becoming publicly available. Selecting the most appropriate product is challenging given end user objectives range from incorporating satellite-derived thickness information in operational ...

Modeled Trends in Antarctic Sea Ice Thickness [PDF]
Journal of Climate, 2014 Abstract Unlike the rapid sea ice losses reported in the Arctic, satellite observations show an overall increase in Antarctic sea ice concentration over recent decades. However, observations of decadal trends in Antarctic ice thickness, and hence ice volume, do not currently exist.

Impact assessment of snow thickness, sea ice density and water density in CryoSat-2-derived sea ice thickness [PDF]
The CryosphereSea ice thickness is an essential climate variable, which is often derived from satellite altimetry freeboard estimates, e.g., by CryoSat-2. In order to convert freeboard to sea ice thickness, assumptions are needed for snow thickness, snow density, sea ...

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

Enhancing sea ice knowledge through assimilation of sea ice thickness from ENVISAT and CS2SMOS [PDF]
The CryosphereArctic sea ice extent has declined significantly over the past four decades, opening up the Arctic to shipping and resource extraction while also impacting wildlife and local communities.

Improving Met Office seasonal predictions of Arctic sea ice using assimilation of CryoSat-2 thickness [PDF]
The Cryosphere, 2018 Interest in seasonal predictions of Arctic sea ice has been increasing in recent years owing, primarily, to the sharp reduction in Arctic sea-ice cover observed over the last few decades, a decline that is projected to continue.

Relationships between Arctic sea ice drift and strength modelled by NEMO-LIM3.6 [PDF]
The Cryosphere, 2017 Sea ice cover and thickness have substantially decreased in the Arctic Ocean since the beginning of the satellite era. As a result, sea ice strength has been reduced, allowing more deformation and fracturing and leading to increased sea ice drift ...

ICESat measurements of sea ice freeboard and estimates of sea ice thickness in the Weddell Sea [PDF]
Journal of Geophysical Research: Oceans, 2008 Sea ice freeboard heights in the Weddell Sea of Antarctica are derived from the Ice, Cloud, and Land Elevation Satellite (ICESat) laser altimeter measurements, which have a unique range precision to flat surfaces of 2 cm within 70 m footprints spaced at 172 m along track. Although elevations of flat surfaces can be obtained to an accuracy of ∼10 cm (1σ)

Environmental Research Letters, 2022 The satellite-observed sea ice thickness (SIT) records from 2003 to 2020 identify an extreme SIT loss during 2010–2011. Ice thickness budget analysis demonstrates that the thickness loss was associated with an extraordinarily large multiyear ice (MYI ...
