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 ...

Impact of sea ice floe size distribution on seasonal fragmentation and melt of Arctic sea ice [PDF]
The Cryosphere, 2020 Recent years have seen a rapid reduction in the summer Arctic sea ice extent. To both understand this trend and project the future evolution of the summer Arctic sea ice, a better understanding of the physical processes that drive the seasonal loss of ...

Sea Ice Modelling and Forecasting [PDF]
New Frontiers in Operational Oceanography, 2018 Sea ice is a fascinating media, of which modelling is in its infancy compared to the ocean and atmosphere. This chapter focuses on the new frontiers in sea ice modelling and forecasting, with particular attention on sea ice dynamics. It is divided in two

Impact of assimilating sea ice concentration, sea ice thickness and snow depth in a coupled ocean–sea ice modelling system [PDF]
The Cryosphere, 2019 . The accuracy of the initial state is very important for the quality of a forecast, and data assimilation is crucial for obtaining the best-possible initial state.

Processes controlling surface, bottom and lateral melt of Arctic sea ice in a state of the art sea ice model [PDF]
Philosophical Transactions of the Royal Society A: Mathematical, Physical and Engineering Sciences, 2015 We present a modelling study of processes controlling the summer melt of the Arctic sea ice cover. We perform a sensitivity study and focus our interest on the thermodynamics at the ice–atmosphere and ice–ocean interfaces. We use the Los Alamos community

Empirical sea ice thickness retrieval during the freeze-up period from SMOS high incident angle observations [PDF]
The Cryosphere, 2014 Sea ice thickness information is important for sea ice modelling and ship operations. Here a method to detect the thickness of sea ice up to 50 cm during the freeze-up season based on high incidence angle observations of the Soil Moisture and ...

neXtSIM: a new Lagrangian sea ice model [PDF]
The Cryosphere, 2016 The Arctic sea ice cover has changed drastically over the last decades. Associated with these changes is a shift in dynamical regime seen by an increase of extreme fracturing events and an acceleration of sea ice drift.

The configuration of Northern Hemisphere ice sheets through the Quaternary
Nature Communications, 2019 How global climatic changes are translated into ice-sheet fluctuations and sea-level change is not well understood. Here the authors present a compilation of empirical data and numerical modelling results of pre-LGM Northern Hemisphere ice sheet changes ...
