Seeing the Unseen—Bioturbation in 4D: Tracing Bioirrigation in Marine Sediment Using Positron Emission Tomography and Computed Tomography
Fig 5
Images of the temporal change in radial bioirrigation.
Left panel: Front and side view of a sediment compartment at different times showing the two cross sections (1: near the feeding pocket; 2: along the burrow shaft) of the burrow. The dashed lines indicate the sediment water interface. Right panel: Development of the bioirrigated area at cross section 1 and 2 after 17, 33 and 52 min (from top to bottom). The circles indicate the burrow circumference. Note the different scales in the two panels.
