Abstract Photosynthetic parameters for netplankton (〉22 μm) and nanoplankton (〈22 μm) varied over similar ranges but exhibited different seasonal and geographic patterns of variation. Nanoplankton a was relatively constant (0.06 mg C [mg Chl · h]-1 [μE m-2 s-1]-1), but P m B (mg C [mg Chl · d]-1) was an exponential function of temperature independent of nutrient concentration and vertical stability in the euphotic zone. The temperature function gives a P m B of 24 at 25°C for nanoplankton growing in an estuarine environment characterized by high nutrient concentrations and a shallow, stratified euphotic zone. Variations in netplankton a and P m B were less predictable and were not correlated with temperature, nutrients or vertical stability. Chain forming diatoms with small cells were able to achieve high α (0.10 to 0.15) and P m B (20 to 24) that were 3 to 5 times higher than large-celled diatoms and dinoflagellates were able to achieve.
