Phytoplankton: Relationships Between Phytoplankton, Nutrients, Oxygen Flux and Secondary ProducersNutrient concentrations and elemental ratios suggest occasional nutrient limitation of phytoplankton production in the region, with a limited phosphorus data set suggesting P-limitation in spring. Nitrogen limitation was possible in approximately one-half of the summer and early fall months sampled
