In the station pages, can a distinction be made between single depth measurements, and profiles? The example shows 3 single depth temperature measurements from 3 different sensors. Can the "0-" part of the depth text be removed? Showing a range of depths is great when it's actually profile data, but none of these are.

Thanks!
