180,"Crest-trough correlation is an estimate of the auto-correlation between the crest heights and the trough depths. In narrow-banded seas this parameter is quite high, because crests and troughs are approximately the same size. Gemmrich, J., Cicon, L.

181,"This is a metric that quantifies the wave-induced mechanical fatigue on the sea-ice pack (0 means broken, 1 means solid). This metric only makes sense in the presence of sea ice."
182,"The x- and y- components of the wave radiative stress to sea-ice are not necessarily equivalent to the u- and v- components (eastward/northward). The x- and y- components strictly follow the defined coordinate system which may or may not follow the eastward and northward directions."
317a,"The atmospheric surface momentum flux is what the atmosphere is losing at the surface of the ocean. The surface momentum flux into the ocean is the momentum flux that is entering the ocean and driving the ocean circulation. The difference is that part of the atmospheric momentum flux goes into the waves and not into the ocean circulation or part of the momentum contained in the wave field that is transferred to the ocean when waves break. In short, the ocean surface has waves which modulate the momentum transfer between the atmosphere and the ocean interior."

@sebvi this part of the sentence confuses me...

The difference is that part of the atmospheric momentum flux goes into the waves and not into the ocean circulation or part of the momentum contained in the wave field that is transferred to the ocean when waves break.

If I assume the "or" is an additional explanation of the difference, then this is how the second part of the sentence would read without the first part, which doesn't make sense to me.

The difference is that part of the momentum contained in the wave field that is transferred to the ocean when waves break.

Is this revision accurate?

The difference is that part of the atmospheric momentum flux goes into the waves and not into the ocean circulation and only part of the momentum contained in the wave field is then transferred to the ocean when waves break.
