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.
