Re: [CF-metadata] vertical coordinate for bed stratigraphy / sediment layers

Dear Jonathan et al., Well, the geomorphologists that I have been in contact with didn't seem to worry about the use of soil_surface for locations that don't have a soil cover yet. One can think of these locations as having (at this moment) a soil cover of zero thickness; this cover could vary

Hello Jonathan, In my view this surface could be considered as the top of the ice, not the bottom and then it can be used as the reference for ice core data. That would remove one problem with 'solid-surface', although Bert doesn't like the term due to his semantic interpretation of 'solid'.

Hi Roy, Jonathan, I hadn't thought much about ice yet; it can be a very difficult subject. There are artic shores (e.g. northern Alaska) which are mostly composed of ice and a little bit of sediment. This part of the ice would most definitely be below the to-be-named surface; this is part of th
