Re: [CF-metadata] is molecular oxygen in seawater always dissolved?

Hi John, In 30 years in oceanography I've never heard any mention of any doubt that it is, at least as far as the usual measurement techniques in oceanogrphy are concerned (polarographic electrodes, Winkler titration and optodes). The labelling 'dissolved' originated in community usage - it's

Re: [CF-metadata] Discussion of technical CF issues as GitHub issues?

Dear All, I can see the sense for the technical issues, but for Standard Name proposal discussions I would prefer to keep to the current system of e-mail plus the CEDA thread-tracking system unless Alison would like to see that replaced by GitHub. Having e-mail thread 'clarification' split

Re: [CF-metadata] new standard names request

Hi Steve, I think there is a CF precedent would pacify you a little here, which is to have Standard Names of the form 'volume_mixing_ratio' with canonical units of dimensionless such as volume_mixing_ratio_of_oxygen_at_stp_in_sea_water. I would suggest following this practice in this case

Re: [CF-metadata] Temporal nitpicks. Was: CF-metadata Digest, Vol 161, Issue 3

Hi Chris, One time zone label (Z for UT) is valid in 8601. In SeaDataNet we took the decision some 10 years back to 'profile' ISO8601 by disallowing any character to the right of the seconds and defining the result as UT. The reason this was done was to prevent data delivery in local time

Hi Alison, First of all, apologies for not commenting sooner - looking at this proposal as been on my todo list, but I hadn't got around to it. However, your e-mail makes it look like you're approaching end game so I thought I'd better provide some input. I would suggest changing the C13

Re: [CF-metadata] New standard names for OMIP biogeochemistry and chemistry

Hello John, I'm getting a little confused here. Why is the dimensionality of the surface measurement different? I would have expected it to be something like mol m-3 for concentrations at any depth. Or am I misunderstanding what you wish to describe? Cheers, Roy. Please note that I

Re: [CF-metadata] New standard names for OMIP biogeochemistry and chemistry

Dear John, Following these comments, I now wonder a little more about your previous comment on differences in dimensionality between your surface concentrations and concentrations at depth. Could you clarify what the units of measure are for your 2D simulations? Are they concentrations per

Re: [CF-metadata] New standard_names for ocean biogeochemistry

Dear All, Some additional information on 'chorophyll-a fluorescence' in observational oceanography. As John says, strictly speaking fluorescence is the amount of radiation within a given waveband resulting from excitation. It could also be expressed as a dimensionless parameter that is the

Re: [CF-metadata] standard name for CDOM

Hello Matthias, The Standard Name: concentration_of_colored_dissolved_organic_matter_in_sea_water_expressed_as_equivalent_mass_fraction_of_quinine_sulfate_dihydrate was set up to describe the measurements made by an ECO. Providing you have done nothing to recalibrate the data from the CTD

Re: [CF-metadata] Silicate vs. dissolved inorganic silicon

Dear All, If one makes the assumption that all the silicon and phosphorus atoms not associated with organic ligands are in a single chemical form associated with oxygen in solution then what Martin says is correct. In my experience I have never known anybody challenge this assumption and I
