N2  - The interstitial water in sediments from coral reef areas and seagrass (T. hemprichii) beds at Lizard Island contained 6-48 µmol l-1 ammonium, 4-7 µmol I-1 nitrate plus nitrite, and 1 .5-2.5 µmol I-1 soluble reactive phosphorus. Concentrations of total dissolved primary amines were an order of magnitude higher in sediments from seagrass beds (about 140 µmol l-1) than from coral reef areas (about 10 µmol I-1). Ammonium-nitrogen was produced at rates of 0.7,6, and 10 nmol g-1 h-1 in sediments from a bare beach, reef flat and seagrass bed, respectively. Added glycine and nitrate were also rapidly metabolized by microbes in the sediment (3 to > 5 nmol g-1 h-1).
