Level-wise wetness at different burial levels. Smooth increase of wetness is observed in obligate (solid blue, circle marker), non-obligate (dashed green, square marker) and crystal packing (dotted red, diamond marker) interfaces. The average Δwetness per level is 0.011, 0.011 and 0.026 for obligate, non-obligate and crystal packing interfaces.
