The doctoral projects in the first cohort will mainly focus on empirical studies along estuarine gradients, that will be complemented with experimental studies in the field, in mesocosms and/or the laboratory and with modeling approaches for integrating ‘biota-mediated effects on carbon cycling’ into estuarine ecosystem models.
Overall, these doctoral projects aim to provide robust insights in ‘biota-mediated effects on carbon cycling’ in marshes, and estuarine channels as well as on carbon fluxes across marsh-water boundaries under current environmental conditions.
