Abstract:The results of a survey of phytoplankton productivity, chlorophyll
a and nutrient concentrations in Pala Lagoon, American Samoa, are shown to be
interpretable in terms of two regimes: an ocean-dominated region where productivity
is controlled by fixed nitrogen concentrations, and a land-runoff-dominated
regime where productivity is unrelated to major nutrient concentration. A quantitative
relationship between nutrient concentrations in the lagoon and phytoplankton
growth rates is presented. This relationship is used as the basis for predicting the
effects of a proposed dredging operation within the lagoon as well as for predicting
the effects of increased waste discharge into the local marine environment.
