||A storm of moderate intensity and lasting for 14 hours was simulated in three of the Marine Ecosystems Research Laboratory (MERL) microcosms by increasing the intensity of microcosm mixing. The simulation resuspended approximately 0.3 cm of sediment and increased suspended particulate loads by 2 orders of magnitude. Concurrently, the concentrations of metals and nutrients increased in the water column. Dissolved metals, but not dissolved nutrients, could have been derived from the pore waters of the resuspended sediment. More likely, remineralization on the benthos and in the water column combined with reduced photosynthesis account for the slight increase observed in nutrient concentrations.
