The N:P molar ratio of fluxes and the Redfield ratio (C:N:Si:P) were calculated.Sediments were also analysed for grain size, OC, TC, TN, TP, Zn, Li, redox and pH. Sediment Grain size (um) categories: fine silt, clay, quartz sand and coarse material (leaves, wood, rocks and shell). Sediment C, N and Total Organic C (TOC) percentages were measured. C:N ratios were calculated for the different sites (cage, north, reference and south). The ratios of Zn:Li and P:Li in sediments were also calculatedThe reference location, a transect through the cages and sites at adjacent mudbanks were sampled for sediment Redox potential (Eh), pH, temperature, and surface dissolved oxygen, temperature and salinity.
