There's another option, I think. The definition for depth_below_geoid
includes
this:
' "Depth_below_X" means the vertical distance below the named surface X.'
There are no other depth_below_X variables on the list, though. In the long
run, I think we should add a mandatory 'reference surface' attribute to the
"plain" depth variable. Have we had that discussion, at least in part?
Anyway,
in the short term, maybe we should add depth_below_sea_floor - it seems
much
clearer than the existing alternatives.

Hi Reyna,
Yes, this is in scope for CF.
There is a standard name height_above_sea_floor (no definition,
canonical units meters) which has the meaning you need, if you use a
negative number for the distance your data is below the sea floor.
If this is not ideal, possibly we could add depth_below_sea_floor
(which is where *I* would look for such data) to the standard names
list. So I sort of hope you ask for that new name. ;-)
I will take advantage of your query to propose a definition for
height_above_sea_floor, to wit: "Height_above_sea_floor is the
vertical distance above the surface of the seabed. Negative values
indicate locations below the seabed."

Hi,
Although most of our data is in the water column, we are also serving
data from beneath the seafloor in boreholes from the IODP program. Is
there a way in the vertical dimension to reflect the combination of
seafloor depth and the meters below seafloor that a sensor is
positioned? Or is this sort of data outside the scope of the CF
convention? We have data like temperature, pressure and resistivity
inside boreholes.
Any recommendations for representation that information would be
appreciated.
