Specific 13C enrichment in solid ecosystem compartments

Specific 13C enrichment (capdelta delta 13C) of seagrass, epiphytes, sheaths, rhizomes, roots, sediment depths (0-2, 2-5 and 5-10 cm), porewater and phospholipid fatty acid biomarkers of microphytobenthos (MPB) and bacteria at multiple timepoints (Day) following stable isotope labelling.Four plots were fertilised with artificial nutrients and four plots served as ambient controls (Treatment). Stable isotope labelling occured 35 days of nutrient enrichment for plot batch 1 (plots 1, 2, 3, 4) and 40 days for plot batch 2 (5, 6, 7, 8).
