def set_heat_capacity(self):
self.heat_capacity = heat_capacity.ocean(self.axes['<STR_LIT>'].delta)<EOL>
Sets the heat capacity of the Ocean Domain.

        Calls the utils heat capacity function
        :func:`~climlab.utils.heat_capacity.ocean` and gives the delta
        array of grid points of it's depth axis
        ``self.axes['depth'].delta`` as input.

        **Object attributes** \n

        During method execution following object attribute is modified:

        :ivar array heat_capacity:  the ocean domain's heat capacity over
                                    the ``'depth'`` Axis.
