Sarah Fawcett(left) could not attend, but her and Dr Katye Altieri (right)students gave presentations during this session. Sarah Fawcett (abstract): Nanoplankton: the dominant vector for carbon export across the Atlantic Southern Ocean in spring.

Suzanne Fietz and the Stellenbosch University Earth Sciences team submitted an excellent e-poster Asmita Singh(e-poster) and Johan Viljoen (abstract) and Jared Walsh(abstract)  were not able to attend the symposium in person.
