Studying the interaction between biotic and abiotic factors in marine ecosystems, characteristics of marine ecosystems, ocean zoning, energy flow and material cycles in marine ecosystems, community structure of marine biota, population dynamics of marine organisms, as well as problems in the use of marine resources and conservation efforts. The study of marine ecology is accompanied by various process skills (minds on activity and hands on activity) which will be used to solve problems in the marine field and their applications. Learning is carried out in the form of theoretical studies, presentations, discussions and practicums in the field.
