This pathway is aimed at students with a broader interest in chemistry and microbiology. The combination of both areas is particularly useful, as many natural chemical processes are microbially determined or moderated. The pathway primarily qualifies students to work in the field of chemical and microbiological environmental analysis and to continue their studies in environmental science Master's degree programmes (in Oldenburg, for example, the consecutive M.Sc. Marine Environmental Sciences or the M.Sc. Microbiology taught in English).

The basic chemical and biological training is expanded with the modules Organic Chemistry and General Microbiology. The pathway provides a comprehensive insight into the fields of geochemistry, environmental chemistry and marine chemistry. Practical skills and basic skills in instrumental analysis are taught in the environmental analysis project study and the practical course in organic chemistry. Students can also acquire skills in basic microbiological working techniques. The Microbial Ecology/Environmental Microbiology module is also a suitable addition.

This pathway focuses on the recording and modelling of physical processes in oceans and coastal waters. The pathway primarily qualifies students for careers in the field of marine environmental monitoring and prevention. It offers an introduction to (physical) marine research, which can be continued by studying a Master's degree programme with a marine focus (in Oldenburg: Marine Environmental Sciences, Marine Sensors and Environmental Modelling).

Basic scientific knowledge is expanded through modules with physical and mathematical modelling content. Basic knowledge of central processes in marine ecosystems is acquired, which can be deepened in various areas (marine ecology, marine biology, marine/geochemistry). The content of the Environmental Physics module focuses in particular on physical oceanography. Ship trips are part of some modules.

This pathway is aimed at students with a broader interest in biological and ecological topics in the marine sector. It primarily qualifies students for work in the field of marine environmental protection and for further Master's degree programmes in these areas (at the University of Oldenburg: M.Sc. Marine Environmental Sciences and possibly the planned Master's degree programme Biodiversity, Ecology, Evolution).

Depending on interest, the focus on marine ecology can be supplemented in this pathway with general marine science or modelling topics. In the compulsory elective area, students deepen their knowledge of ecology and microbiology. As an accentuation, advanced knowledge in the biotic ecology of marine environmental systems is acquired. The acquisition of knowledge and skills in the field of modelling is a useful addition. Practical skills are taught (depending on the focus) in the project studies Oceanography or Environmental Modelling.

This degree programme focuses on teaching methodological skills for describing and analysing terrestrial ecosystems with regard to environmental planning and environmental law. This pathway primarily qualifies students for academic appointments in the field of environmental protection (in particular nature conservation and environmental planning) and for further Master's degree programmes with a focus on landscape ecology, nature conservation and environmental planning (at the University of Oldenburg the M.Sc. in Landscape Ecology).

Knowledge of the various compartments and processes of Central European (especially terrestrial) ecosystems is imparted. In-depth knowledge of environmental planning and environmental law is acquired through modules in the areas of environmental planning and environmental law, spatial development and conflicts of land use. These can be supplemented in the areas of plant/vegetation ecology, animal ecology, aquatic ecology and (depending on the student's interests). The application of geoinformation systems is an important part of this training programme.

This pathway primarily qualifies students for academic appointments in the field of environmental analysis and for further Master's degree programmes in environmental sciences (at the University of Oldenburg the M.Sc. Marine Environmental Sciences). The course provides solid basic knowledge of analytical sampling and sample preparation, the physical-chemical principles for separating and detecting inorganic and organic substances and the instrumental-analytical characterisation of substances in real samples (soils, rocks, surface water, groundwater and seawater).

This pathway primarily qualifies students for academic appointments in the field of microbiology and for further Master's degree programmes with a focus on environmental sciences (at the University of Oldenburg the M.Sc. Microbiology and M.Sc. Marine Environmental Sciences). The degree programme provides solid knowledge of micro- and cell biology, metabolism, taxonomy, phylogeny, diversity and distribution of microorganisms. Students also acquire basic microbiological working techniques.
