Last checked: 23 Aug 2026 UTCOverview
This unit investigates the organisms and the processes that drive marine ecosystems. We deal with the trophic structure of marine ecosystems, including primary and secondary production, microbial loops, food webs and their importance for marine fisheries. The implications of the characteristic life cycles of marine organisms to their geographical distribution are also considered. These topics are placed in the context of specific marine ecosystems including coastal habitats, coral reefs, open oceans, the deep sea and polar ecosystems. The practical component comprises a field course in February where you will work in small groups on specific aspects of marine biology.
