Phytoplankton and Primary Production

Learning Outcomes

Learning Outcomes

Having successfully completed this module you will be able to:

• Explain the main factors influencing phytoplankton production and carbon recycling in the surface ocean.
• Demonstrate skills in the analysis and presentation of data sets and the setting of such results within the context of current literature
• Describe the fundamental processes of phytoplankton photosynthesis and primary production in the ocean.
• Apply basic practical laboratory methods for observing phytoplankton, quantifying their biomass and determining photosynthesis and respiration rates.

An introduction to the euphotic zone and its biology; light in the ocean, photosynthesis and respiration; chemosynthesis; the algal cell, pigments, sampling and preservation; description of major phytoplankton groups; definitions of primary production; measurement of primary production; light and photosynthesis, phytoplankton growth and critical depth model; nutrients and phytoplankton growth; oceanic regions of phytoplankton production; global phytoplankton production; sources and sinks of dissolved organic matter; marine bacteria biomass and production; the microbial loop; modelling marine primary production, phytoplankton production and global change.

Practicals:

1. Determination of chlorophyll and phosphate in samples collected from algal culture.

2. Oxygen production incubation experiment.

Formal lectures: will provide an introduction to the theory underlying the fundamental processes of marine phytoplankton photosynthesis and planktonic primary production.

Laboratory classes: will provide you with a basic introduction to practical methods for determining samples collected and experimentation. Laboratory safety awareness.

A wide range of support can be provided for those students who have further or specific learning and teaching needs.
