Marine Ecologist

South Africa’s marine environment is rich in biodiversity, with over 10 000 recorded marine plant and animal species and over 150 distinct ecosystem types with habitats ranging from cool-water kelp forests to subtropical coral reefs. However, overfishing, unsustainable fishing and pollution exacerbated by the effects of climate change, threaten these ecological systems and their capacity to support livelihoods. Investigation of marine habitats, populations and interactions within marine ecosystems assists us in rehabilitation and sustainability actions within the marine environment.

Marine ecologists research marine ecosystems, focusing on interactions of organisms within their surrounding environment. They study the biochemical, cellular, individual and community characteristics of marine organisms and their connection to the ecosystem and biosphere. They also observe, collect and test samples from marine ecosystems to identify conservation opportunities and challenges. Some can also develop environmental education programmes to build ecological knowledge in local communities.

Marine ecologists can work within open, deep-sea or coastal marine ecosystems and may work underwater using scuba diving gear. They can analyse collected data in laboratories, returning to an office environment to write up reports and findings.
