30    C     |
31    C     | "Correction Step"
32    C     | =================
33    C     | Here we update the horizontal velocities with the surface
34    C     | pressure such that the resulting flow is either consistent
35    C     | with the free-surface evolution or the rigid-lid:
36    C     |   U[n] = U* + dt x d/dx P
37    C     |   V[n] = V* + dt x d/dy P
38    C     |   W[n] = W* + dt x d/dz P  (NH mode)
39    C     |
40    C     | "Calculation of Gs"
41    C     | ===================
42    C     | This is where all the accelerations and tendencies (ie.
43    C     | physics, parameterizations etc...) are calculated
44    C     |   rho = rho ( theta[n], salt[n] )
45    C     |   b   = b(rho, theta)
46    C     |   K31 = K31 ( rho )
47    C     |   Gu[n] = Gu( u[n], v[n], wVel, b, ... )
48    C     |   Gv[n] = Gv( u[n], v[n], wVel, b, ... )
49    C     |   Gt[n] = Gt( theta[n], u[n], v[n], wVel, K31, ... )
50    C     |   Gs[n] = Gs( salt[n], u[n], v[n], wVel, K31, ... )
51    C     |
52    C     | "Time-stepping" or "Prediction"
53    C     | ================================
54    C     | The models variables are stepped forward with the appropriate
55    C     | time-stepping scheme (currently we use Adams-Bashforth II)
56    C     | - For momentum, the result is always *only* a "prediction"
57    C     | in that the flow may be divergent and will be "corrected"
58    C     | later with a surface pressure gradient.
59    C     | - Normally for tracers the result is the new field at time
60    C     | level [n+1} *BUT* in the case of implicit diffusion the result
61    C     | is also *only* a prediction.
62    C     | - We denote "predictors" with an asterisk (*).
63    C     |   U* = U[n] + dt x ( 3/2 Gu[n] - 1/2 Gu[n-1] )
64    C     |   V* = V[n] + dt x ( 3/2 Gv[n] - 1/2 Gv[n-1] )
65    C     |   theta[n+1] = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
66    C     |   salt[n+1] = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
67    C     | With implicit diffusion:
68    C     |   theta* = theta[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
69    C     |   salt* = salt[n] + dt x ( 3/2 Gt[n] - 1/2 atG[n-1] )
70    C     |   (1 + dt * K * d_zz) theta[n] = theta*
71    C     |   (1 + dt * K * d_zz) salt[n] = salt*
