Data from gliders in Ocean topic

[paul4devon]

Is it possible to clarify whether the confirmed current topic hierarchy (i.e not experimental) for Gliders which part of the ocean topic structure - earth-system-discipline/ocean/surface-based-observations/gliders is indeed correct as data from gliders isn't surely expected to be at the surface level.

Should it not be sub-surface-based-observations? as this has suggested by data experts in the field.

• current topic hierarchy is +/ocean/surface-based-observations/gliders
• In general, we the topics are normalized around the two "spatial" categories identified the WMO Unified Data Policy: space-based-observations and surface-based-observations

@paul4devon please note that the topic for gliders is now:
/ocean/surface-based-observations/autonomous-underwater-vehicles
