Was there something wrong with the term 'profile'? I thought that was reasonable. Some profiles will not be regular, and I think that's OK.

Yes, "profile" is correct, there were some places i inadvertantly used "profiler". Just wondering if there was a better generic name.


Re the Z axis, it would be nice to know for sure whether the Z axis should be interpreted as 'surface'. (Other possible surfaces exist, and I suppose an abstract form of Z is also possible. So if we want determinism, we could either say "lack of characterization always means surface" or "Z must be described, if only to say it is 'surface'.")

Yes, after thinking more about it, Im not so sure we should allow data that doesnt have a z coordinate. A standard I think should be allowed to insist on things like this.

- "profiler" in the atmospheric community is used
extensively for the
name of an instrument that produces "profiles".  I would recommend
changing your "profiler" to "profile" to remove this confusion.  A
RAOB sounding is a profile, but people do not refer to the
instrument
as a profiler necessarily.
ok. anyone with a better name is welcome to offer it. What is
"data that has an array of values along the vertical dimension"?

For oceanographic moorings we have "profile" data, such as what comes
from an Acoustic Doppler Current Profiler, and data that we call "string"
data such as what comes from a series of instruments (CTDs, Radiometers)
mounted on a vertical rope or wire beneath the buoy.

Profile data is usually stored on a regularly spaced Z-axis and string
data is stored on an irregular Z-axis as the depths are often like 1, 10,
20, 40, 60, 80, 100, 150, 200, 250, and 300 meters.
