Careers and outcomes
A BSc (Hons) Marine Biology degree prepares you for diverse careers in:
"After graduating from Essex I was appointed as a research supervisor at the Archipelagos Insitute of Marine Conservation in Greece. Through researching the marine ecosystems of the Mediterranean Sea, I was exposed to a very different environment to the estuaries and salt marshes of Essex! From shallow coastal seagrass meadows to deep-sea coralligenous habitats, and the vast diversity of fish and invertebrates they host. My journey into environmental research progressed when I was offered a research Masters back at Essex. In collaboration with Project Seagrass, I will be focusing on seagrass restoration and recovery in the southern North Sea, hoping to further this important research and potentially contribute towards climate change initiatives."
