| At two intertidal sites (one sandy and one silty, in the Scheldt estuary, The Netherlands), the fate of microphytobenthos was studied through an in situ <sup>13</sup>C pulse- chase experiment. Label was added at the beginning of low tide, and uptake of <sup>13</sup>C by algae was linear during the whole period of tidal exposure (about 27 mg m<sup>-2</sup> h<sup>-1</sup> in the top millimeter at both sites). The <sup>13</sup>C fixed by microphytobenthos was rapidly displaced toward deeper sediment layers (down to 6 cm), in particular at the dynamic, sandy site. The residence times of microphytobenthos with respect to external losses (resuspension and respiration) were about 2.4 and 5.6 d at the... |
