Introduction to general aspects of biological oceanography from phytoplankton to fish. The module is designed for students with no previous experience of studying biological systems. The module follows the flow of energy from light, via primary producers and then through the food chain in a number of typical oceanic systems - from coastal to open-ocean. Students will learn the importance of microbial processes and their role in the cycling of carbon, energy and thus in the regulation on global climate. Students will also be introduced to the range of methods used to measure and interrogate the biological components of ocean systems. Students will learn via a series of lectures and guided background reading. Students will gain practical experience through the sampling and data analysis of an estuarine marine systems; this data will be used as the basis of a short report describing the biological components of this system.
