An abstract data type which represents whatever lies below a glacier. This could be the ground, a plume, or a fully dynamic ocean model. Methods are available to provide the coupling information between the glacier and the basal surface.
| procedure(get_scalar), public :: basal_melt | Returns the basal melt rate. |
| procedure(get_scalar), public :: basal_drag_parameter | Returns a value which may be needed to calculate basal drag, such as the coefficient of friction. |
| procedure(get_real), public :: water_density | Density of the water at the basal surface. |
| procedure(setter), public :: update | Sets the state of the basal surface |
| procedure(get_i), public :: data_size | Returns the number of elements in the basal surface's state vector |
| procedure(get_r81d), public :: state_vector | Returns the basal surface's state vector, a 1D array with all necessary data to describe its state. |
| procedure(read_dat), public :: read_data | Read the basal surface data from an HDF5 file on the disc. |
| procedure(write_dat), public :: write_data | Writes the data describing the basal surface to the disc as an HDF5 file. |
| procedure(surface_solve), public :: solve | Solves for the state of the basal surface given a particular ice shelf geometry. |
