Dear John,

Thank you for your proposal.

We currently have one existing standard name relating to turbidity of sea water, secchi_depth_of_sea_water, which has units of metres and is defined as 'Depth is the vertical distance below the surface. A Secchi disk is a patterned disk that is used to measure water transparency in oceans and lakes. The disk is lowered into the water and the depth at which the pattern is no longer visible is the called the secchi depth.'

I agree with Jonathan that it would be helpful if you could provide a (fairly brief) definition for the new name or perhaps a suitable reference.

Best wishes,
Alison

Dear CF-Metadata,
I would propose the addition of "sea_water_turbidity" to the CF Standard Names. This has units of NTU (Nephelometric Turbidity Units), which would be represented in UDUNITS as "1e-3" (similar to how sea_water_salinity is in PSS (or PSU) and commonly represented as 1e-3).
Thanks,
