C *==========================================================* |

C | SUBROUTINE INI_SALT |
| 13 |
C | o Set model initial salinity field. |
| 14 |
C *==========================================================* |
| 15 |
C | There are several options for setting the initial |
| 16 |
C | temperature file |
| 17 |
C | 1. Inline code |
| 18 |
C | 2. Vertical profile ( uniform S in X and Y ) |
| 19 |
C | 3. Three-dimensional data from a file. For example from |
| 20 |
C | Levitus or from a checkpoint file from a previous |
| 21 |
C | integration. |
| 22 |
C | In addition to setting the salinity field we also |
| 23 |
C | set the initial salinity tendency term here. |
