| Description | Results available so far cover the eastern half of the South Atlantic basin. The results indicate that the South African margin supplies a smaller amount of iron to the ocean continental margins than in other areas studied. This is significant because iron is a biologically essential micronutrient with the potential to enhance (if available) or restrict (if scarce) the amount of phyotosynthetic productivity in the surface ocean, and thus the amount of CO2 drawn down into this region of the ocean. |
| Exploitation Route | Climate prediction helps UK strategy These results will provide essential data inputs to models of carbon cycling between the oceans and atmosphere, and therefore refine climate model predictions. |

| Impact | The EAC Committee report urges Government action to stop using seas as a sewer. Specific impact of my contribution included a statement that Govt should commit not to pursue licences for seafloor massive sulfides within UK jurisdiction. The UK should use its significant influence to impose a moratorium on licences outside UK jurisdiction and work with the International Seabed Authority to ensure robust Environmental Impact Assessments that are based on the precautionary principle and make the best use of available scientific evidence. |

| Results and Impact | Exploring our Oceans has reached a global audience (over 35,000 sign ups), and our learners have a wide range of backgrounds and motivations for taking the course. The course design and FutureLearn platform ensures accessibility for all. Videos introduce key concepts at a basic level, and accompanying text expands on video content. Extended reading opportunities and links to external organisations, provide signposting for broader learning and engagement. Links to open access papers stretch participants for deeper advanced learning. Our postgraduate facilitators develop their public engagement skills and confidence via asynchronous discussion of emotive subjects within the community. Delivering such a course has enabled the Faculty to test new technologies and activities at scale before use with on-campus students. Nelson Mandela University is a contributor to the course as part of a Newton grant (ESRC: ES/N013913/1 Capacity building and PhD student partnership with Nelson Mandela University in the Marine and Maritime sectors, 2015-2018). Part of the legacy of this project includes sharing learning resources and capacity building for developing online learning in South Africa. Summary of Impacts • Maintained a significant 4 year presence on a global online platform • Boosted applications to undergraduate programmes and engaged with our incoming students during the recruitment cycle • Promoted our research in deep sea exploration • Built on a 4*REF2014 Impact Case Study: Exploring the Deep: Public Engagement with Deep Ocean Research and provided clear metrics on reach and impact of learner experience. • Developed our graduate students' skills in communication, impact and engagement • Delivered our Newton funded project goals to transform marine postgraduate education in South Africa in partnership with Nelson Mandela University, • Helped to build our international partnerships worldwide |
