    At the end of section 2 and throughout section 3 no comment is made about using acoustic travel-time measurements, a form of constraint mentioned in the cited papers related to the ECCO project. It is possible that these would provide a stronger constraint than a few individual mooring site observations. Also, the low resolution of the model compared to some the processes affecting the various data streams means that not all information in the data is usable; a probable advantage of path averaged travel-time measurements of heat content may be that the physical scales governing the data and those explicit in the model are better matched.

    Dear Tim,

    Thanks for your comment. I agree that acoustic tomography data could provide a useful integral constraint on models. Some ECCO folks have tried constraining models with that data type before. But to my knowledge, acoustic topography data were not assimilated by the current ECCO-GODAE system. I am not aware of other ocean data assimilation systems described in this CWP using this data type either.
