Atoll Morphometry Controls Lagoon Nutrient Regime

Nutrient control of phytoplankton was studied in 12 atoll lagoons of contrasting morphology in the Tuamotu Archipelago in the South Pacific. In large lagoons and in small lagoons well open to the ocean, N limitation was indicated by dissolved inorganic N (DIN,$NO^-_3 + NO^-_2 + NH^+_4) < 0.5 \mu$...

Summary:Nutrient control of phytoplankton was studied in 12 atoll lagoons of contrasting morphology in the Tuamotu Archipelago in the South Pacific. In large lagoons and in small lagoons well open to the ocean, N limitation was indicated by dissolved inorganic N (DIN,$NO^-_3 + NO^-_2 + NH^+_4) < 0.5 \mu$M, by DIN/P-PO4ratios$
