Re: [CF-metadata] standard names for sediment trap data

Hello Jonathan, The problem is that these terms come from different communities, where they are in common usage. How do we decide which communities usage to adopt? Maybe sticking with the geochemists (who instinctively know what 'total iron' means) and being explicit with the biogeochemistry (i

Dear Roy > iron to total_iron (defined as all oxidation states) > silica to total_silica (defined as biogenic + lithogenic) > manganese to total_manganese (defined as all oxidation states) I have reservations about that, because I think the word "total" is not self- explanatory. You have to know
