Dear All,
I think a new Standard Name 'sea_floor_depth_below_sea_surface' is what's needed here. My definition for this would be 'The vertical distance between the sea surface and the seabed at a given point in space and at a given instant in time or averaged over a time interval that is significantly less than a tidal cycle (1 hour or less).' This may seem complicated, but is needed to cover BPRs which do some averaging to smooth out waves. My take on 'height_above_sea_floor' would be as the z co-ordinate for something inside a water body.
May be worth pointing out to Jeff that there is already 'sea_water_pressure_at_sea_floor' for BPR data that haven't been converted to depth.
I've expressed this as a depth rather than as a height to be consistent with 'sea_floor_depth_below_sea_level' and so we don't end up with different terms for the same quantity depending upon whether one is looking upwards or downwards.
Cheers, Roy.

Subject: [CF-metadata] seeking CF name for total water column height
Hello-
I am a new subscriber. We are hoping to adopt CF names wherever possible in the context of the Integrated Ocean Observing System (IOOS) Sensor Observation Services (SOS). Not all phenomena we measure have immediately apparent CF names, however. We are using this URL as a reference:
http://cf-pcmdi.llnl.gov/documents/cf-standard-names/standard-name-table/current/cf-standard-name-table.html
The first example is total water column height as derived from a bottom pressure recorder associated with a tsunami warning buoy. This is not sea_surface_height_above_reference_ellipsoid or _above_sea_level. It might be height_above_sea_floor but we're not really sure what that refers to (height of what?).
Is there a standard name present or planned that is equivalent to total_water_column_height?
Thanks for any information,
Jeff DLB
