As agreed in the namelist discussion, all parameters assiciated with tidal momentum forcing will be turned off.

According to OM2-0.25deg, GFDL OM4 0.25deg, and GFDL OM5 0.25deg, turbulent mixing generated by breaking internal gravity waves is parameterised for local dissipation at internal tide generation sites (INT_TIDE_DISSIPATION). However, we currently lack external input data for averaged tidal flow amplitudes (tideamp.nc) under /g/data/vk83/experiments/inputs/access-om3. So I will keep these parameters off at this stage.

Yes, in the namelist discussion we meant that explicit tides (tidal momentum forcing) should be turned off, which is what you've done in https://github.com/COSIMA/MOM6-CICE6/pull/77/files.

I agree the parameterised tidal dissipation should be turned on when we have the appropriate input files. We have some from OM2 - maybe they could be used, at least until we have some with proper provenance?

I agree. I’ll merge that PR, and once we have the input files with proper provenance, I’ll submit another PR to address the tidal dissipation parameterizations.
