Thanks Chris,
Totally agree - I was planning to say exactly this in a posting later today.
Actually the SeaOWL measures both fluorescence and backscatter, but that's nit-picking. Chlorophyll fluorometers have Standard Names pertaining to chlorophyll concentration - it's the geophysical phenomenon resulting post-calibration that counts. In the case of the SeaOWL this is described in the instrument specification as 'crude oil'.
Note that I wasn't suggesting ONLY fulfilling the SeaOWL use case, just getting something in place quickly that covers it. Covering other use cases - without going too generic - is all to the good in my view.
So, I'm still rooting for 'mass_fraction_of_crude_oil_in_sea_water' or 'mass_concentration_of_crude_oil_in_sea_water'.
Cheers, Roy.

Thanks - I understand. In choosing CF standard names we generally assume that
the intention is to be comprehensive by default, and we add more words in order
to be specific, for example atmosphere_optical_thickness_due_to_cloud means
all kinds of cloud, and atmosphere_optical_thickness_due_to_convective_cloud
is more restrictive. Omitting "total" in your name would be consistent with
this pattern, in order to mean all phases.
Indeed -- however, the "total" in "total petroleum hydrocarbons" is very much part of the name in common usage. And I think the "total" refers both to phase: droplets vs dissolved, and also to the multiple compounds and classes of compound, like in contrast, with, say" Polycyclic aromatic hydrocarbon" (PAH). So I say we keep the "total" in the name.

If someone is concerned about what the instrument measures, I'd ask someone technical at the company of TPH captures it for them.
(after all, what the instrument REALLY measures is Fluorescence...)
