Low level nutrient enrichment of an enclosed water column caused increases in primary, secondary and tertiary production. In addition, increases in the amount of sediment material, heterotrophic activity and accumulation of major nutrients, nitrate and phosphate, were noted. In contrast, no change was observed in species diversity that could be attributed to nutrient enrichment. The combination of these effects is suggested as a diagnostic approach to examining the early effects of marine eutrophication.
