The emphasis is on basic principles that help us to understand the processes that shape life in marine environments. This topic introduces marine organisms and the physical and biological processes that affect them. Initially it begins with an investigation into the geologic processes behind the formation of ocean basins, the causes and maintenance of currents and ocean circulation, and the physical factors influencing primary productivity in marine environments.
Afterwards transits it into an exploration of various marine organisms, as well as the physiological adaptations these organisms must the marine environment. Overall, the prominence is on the physical factors behind the emergence and preservation of marine ecosystems, and the complex biological interactions between them.
