|---|
| 6 | ``Sea Ice Modelling Integrated Initiative'' (\SIcube) is the sea ice engine of |
|---|
| 7 | the \NEMO\ ocean model (``Nucleus for European Modelling of the Ocean''). |
|---|
| 8 | It is intended to be a flexible tool for studying the sea ice dynamics and thermodynamics, |
|---|
| 9 | brine inclusions and subgrid-scale thickness variations (``white ocean''), |
|---|
| 10 | as well as its interactions with the other components of the Earth climate system over |
|---|
| 11 | a wide range of space and time scales. |
|---|
| 12 | \SIcube\ is interfaced with the \NEMO\ ocean engine, and, |
|---|
| 13 | via the \href{http://portal.enes.org/oasis}{OASIS} coupler, |
|---|
| 14 | with several atmospheric general circulation models. |
|---|
| 15 | It also supports two-way grid embedding by means of the \href{http://agrif.imag.fr}{AGRIF} software. |

| 17 | %% Specific part |
|---|
| 18 | Designed for global to regional applications up to $~$10 km of effective resolution, |
|---|
| 19 | \SIcube\ is a curvilinear grid, finite-difference implementation of the classical AIDJEX model |
|---|
| 20 | (Arctic Ice Dynamics Joint EXperiment), |
|---|
| 21 | combining the conservation of momentum for viscous-plastic continuum, |
|---|
| 22 | energy and salt-conserving halo-thermodynamics, |
|---|
| 23 | an explicit representation of subgrid-scale ice thickness variations, snow and melt ponds. |
|---|
| 24 | An option to switch back to the \textit{single-category} (or \textit{2-level}) framework provides |
|---|
| 25 | a cheap sea ice modelling solution. |
