Abstract
This paper deals with nutrient dynamics caused by sediments resuspensioin noxygen-depleted offshorea rea.I ti sconsidered that ammonium (NH4-N) adsorbs to sediments and nutrient cycling varies with decomposition of particle organic matter in resusupend sediments in laboratory experiments. As a result, for one thing, Water-sediment partition of NH4-N which indicates sorbable amounts is formulated using dissolve oxygen in water column. For another, as well as thetime when it is stationary culture when it is suspension culture for sediments, concentration of NH4-N variation in water column is related C/N ratio in sediments and it is indicatetd hat concentration of NH4-N variation have a seasonalitypattern from laboratory experiments.
