Detailed Description

Implements the ocean model used in [Martinetal2011].

Uses a parameterization of sub-shelf melting with respect to sub-shelf heat flux like in [BeckmannGoosse2003].

Models heat flux into the base of the shelf as

\[ Q_{\text{heat}} = \rho_{o} c_{p_{o}} \gamma_{T} (T_{o} - T_{f}), \]

where $\rho_{o}$ is the density of ocean water, $c_{p_{o}}$ and $T_{o}$ are the heat capacity and temperature of the ocean mixed layer, $T_{f}$ is the freezing temperature of ocean water at the shelf bottom.
