C *==========================================================* |
| 17 |
C | SUBROUTINE SBO_CALC | |
| 18 |
C | o Do SBO diagnostic output. | |

C *==========================================================* |
| 20 |
C | NOTE: The following subtleties are ignored for time | |
| 21 |
C | being but may need revisiting at some point in time. | |
| 22 |
C | 1) The model is volume-preserving and Boussinesq so | |
| 23 |
C | quantities like oceanic mass need to be interpreted | |
| 24 |
C | with some care. We remove spurious mass variations | |
| 25 |
C | using the Greatbatch correction. Real freshwater | |
| 26 |
C | fluxes retained in mass load. | |
| 27 |
C | 2) The sea surface height variable etaN might lag other | |
| 28 |
C | prognostic variables by half a time step. This lag | |
| 29 |
C | is ignored in SBO computations. | |
| 30 |
C | 3) OAM due to currents assumes constant density | |
| 31 |
C | (=rhoConst), rms differences using variable density | |
| 32 |
C | is less than 1%, assuming rhoConst is a good measure | |
| 33 |
C | of the actual mean density | |
| 34 |
C | 4) Seaice motion added to OAMC. Seaice mass is in OAMP | |
| 35 |
C | and COM. Net freshwater flux is between atmosphere | |
| 36 |
C | and liquid ocean plus seaice. I.e. changes in seaice | |
| 37 |
C | mass due to melt/freeze with liquid ocean do not | |
| 38 |
C | change net freshwater flux. | |
