Promotionsvorhaben
Die 15 Promotionsprojekte der ersten Kohorte werden sich hauptsächlich auf empirische Studien entlang der Ästuargradienten konzentrieren, die durch experimentelle Studien im Feld und/oder im Labor sowie durch Modellierungsansätze zur Integration von "biota-vermittelten Effekten auf den Kohlenstoffzyklus" in die Ästuar-EM ergänzt werden. Insgesamt zielen diese Promotionsprojekte darauf ab, Erkenntnisse über "Biota-vermittelte Effekte auf den Kohlenstoffzyklus" in Sümpfen und Ästuarkanälen sowie über Kohlenstiffflüsse über Sumpf- und Wassergrenzen unter aktuellen Umweltbedingungen zu liefern.
