Â鶹´«Ã½¸ßÇå°æ

This interdisciplinary degree provides an in-depth study of the biological, chemical and physical processes of the oceans, seas and estuaries. You will embark on a detailed study of life in the sea, from the smallest bacteria to the largest mammals. This knowledge will be underpinned  by a specialised understanding how the different marine habitats are affected by key physical (currents, tides, waves and ocean mixing) and biogeochemical (carbon cycle, nutrient recycling by the microbial loop) processes that mediate interactions between the atmosphere, ocean and sea floor.

This is a 4-year course. During the first 3 years, you will follow the same degree course structure as Marine Biology and Oceanography BSc. In Year 4 you carry out a substantial piece of research which forms your fourth year dissertation.
