I agree, Jonathan. I replied, off-list, because I was concerned that the
requested
standard name was more specific than the definition seems to warrant.
There are,
I'm supposing, other reasons why the observed oxygen would be lower
than the
saturation oxygen, other than oxygen utilization.
So, I think difference_of_oxygen* is a good choice.

Dear Ajay
I hadn't replied because I'm not an expert in this subject. On general grounds,
following the usual approach of CF standard names, I'd suggest that something
more self-explanatory would be better than apparent_oxygen_utilization. Given
your definition of what it means
definition: the difference between saturation oxygen content and observed
oxygen content.
what about
difference_of_oxygen_per_unit_mass_in_sea_water_from_saturation
We have other standard names with "difference" in them, for example
difference_of_air_pressure_from_model_reference
and we have quantities in mol kg-1, for instance
moles_of_oxygen_per_unit_mass_in_sea_water
and I'm basing my suggestion on those.
The canonical unit for the standard name table should be mol kg-1, but you
could have micromol kg-1 as your units, since they're physically equivalent.
Cheers
Jonathan

Subject: Re: [CF-metadata] Request for new standard-name:
apparent_oxygen_utilization
Hi All,
I had requested for a new standard name for apparent_oxygen_utilization
during the last week of November. Since, there have been no discussions on
it, I wanted to quickly
follow up on it.
Thanks,
Ajay

Dear CF community,
On behalf of NODC, I would like to request for a new standard name:
apparent_oxygen_utiliziation (AOU)
definition: the difference between saturation oxygen content and observed
oxygen content.
units: micromoles/kg
Description is from Broecker and Peng, 1982, Tracers in
the Sea
http://www.ldeo.columbia.edu/~broecker/Home_files/
TracersInTheSea_searchable.pdf
(pp 131-138)
Some more detail in Garcia et al., World Ocean Atlas
Volume 3: Dissolved Oxygen, Apparent Oxygen Utilization, and
Oxygen Saturation.
