Differential response of equatorial Pacific phytoplankton to iron fertilization
Article Abstract:
Phytoplankton biomass can be significantly increased by the addition of iron, according to experiments in the equatorial Pacific Ocean. Flow cytometry and liquid chromatography were used to analyze the responses of 5 groups of phytoplankton. The groups that dominated the community before the experiment doubled in cell number, while another group decreased. An initially rare group increased 15-fold.

A dual sheath flow cytometer for shipboard analyses of phytoplankton communities from the oligotrophic oceans
Article Abstract:
A dual sheath flow cytometer has been designed for the study of phytoplankton communities across the size range of natural samples. Addition of the dual-sheath capacity and adjustable optics to a flow cytometer facilitates study of pico-, ultra- and nanophytoplankton without lengthy changeover times. Real-time analyses can thus be performed at sea across the phytoplankton size spectra.

Frequency distributions of phytoplankton single-cell fluorescence and vertical mixing in the surface ocean
Article Abstract:
A major challenge for oceanographers has been understanding vertical mixing processes in the surface oceans and its effect on phytoplankton photoacclimation. This understanding is necessary for predicting the effects of ultraviolet radiation on phytoplankton and for interpreting ocean color observations. Phytoplankton can be used as biological tracers for vertical mixing.
