Ammonium (NH4+) concentrations were measured in sediment-core samples from four creeks in North Inlet, Georgetown, South Carolina. It is hypothesized that ammonium is released from sediments in intertidal systems. Sediment cores 14 cm X 4.7 cm, with a 6.5 cm water filled top space, were incubated at 25°C for two hours. 20 ml samples were taken every 30 minutes. Control cores of 20.5 cm X 4.7 cm were also incubated and sampled with the same protocol. The ammonium concentrations from the samples in all four creek sediment-cores exhibited lower levels than the controls.
