AMMONIUM AFFINITY OF SEDIMENTS AT LIZARD ISLAND, GREAT BARRIER REEF, AUSTRALIA
We measured ammonium affinities and chlorophyll a concentrations of sediments at Lizard Island in August 1997. Surficial sediments were collected from a reef flat, seagrass bed and lagoon, spiked with ammonium and incubated in the light or dark.
Nearly all sediments took up ammonium. The exceptions were sediments from the lagoon that were incubated in the dark. They released ammonium. Sites and light influenced ammonium affinities of the sediments. Affinities were greatest and least in sediments from the reef flat and lagoon respectively. Affinities were greater in the light than in the dark. Ammonium affinities and chlorophyll a concentrations of sediments from the reef flat in light were positively correlated.
