This study focused on organic particles withrespect to their transport and sedimentarymineralisation in a North Sea intertidalsandflat previously characterised as stronglyinfluenced by advective transport across andbelow the water-sediment interface. Measuredpermeabilities of the sandy sediment rangedfrom 5.5 to 41⋅10−12 m2, andpermeabilities calculated from granulometricdata exceeded the measured values by a factorof 4.4 ∓ 2.8. Bacteria (2–9% of the POC)were highly variable in space and time. Theywere less mobile than interstitial fine (<70 µm) organic and inorganic particles, aspart of the population lived attached to large,heavy sand grains. The vertical distribution ofbacteria was closely related to the organiccarbon content of the fine...
