Table 1 Physicochemical parameters measured at the stations (see Fig. 1A-C). The substations “inside, edge, and outside” (see Fig. 1D) were averaged because the differences were minimal. Zostera marina shoot length was determined from inside samples. (Chl a = Chlorophyll a, DOC = dissolved organic carbon, PON = particular organic matter, DN = dissolved nitrogen, NA = not available)
From: Low impact of Zostera marina meadows on sediment and water microbiota under brackish conditions
