Photosynthesis, productivity and growth, the physiological ecology of phytoplankton

The present volume gives an overview about records of measurements of primary productivity and related topics in the lakes and oceans of the world. Planktonic algae (phytoplankton) exist in a three-dimensionally intermittently mixed environment. For many years limnologists and oceanographers have been measuring the primary productivity of phytoplankton by suspending water samples, containing phytoplankton, in the water and measuring the exchange of oxygen and carbon which takes place or have been taking water samples to the laboratories, and measuring the productivity under controlled conditions.
