PHYTOPLANKTON
Objectives
1. To introduce the major groups of marine phytoplankton, namely the cyanobacteria, coccolithophores, silicoflagellates, diatoms, and
dinoflagellates.
2. To introduce unique ecological and evolutionary adaptations of phytoplankton.
3. To describe methods by which primary productivity is measured in the ocean.
4. To detail factors that affect primary productivity, namely light, nutrients, and grazing.
5. To describe the pigments necessary for photosynthesis in the sea, with particular emphasis on accessory pigments.
