The Fawcett lab is interested in understanding the complex relationships between biogeochemical fluxes (particularly nitrogen (N) fluxes) and primary productivity in the ocean, with implications for past and future climate, ecosystem structure and function, ocean fertility, and global biogeochemical cycles. The lab’s principal tool is the natural abundance distributions of the stable isotopes of dissolved and particulate N forms, which provide an integrative view of biogeochemical and physical processes that are highly variable in time and space. The isotopes can be coupled with techniques such as flow cytometry and biological rate measurements, and integrated into biogeochemical models to yield high resolution insights into marine ecosystems.

Lab updates

December 2017: Sarah has been awarded a P-rating by the National Research Foundation. “The President’s rating is for young researchers less than 35 years of age who have held a Ph.D. for less than 5 years. Researchers in this group are recognized by all or the overwhelming majority of the reviewers as having demonstrated the potential of becoming future international leaders in their field on the basis of exceptional research performance and output from their doctoral and/or early postdoctoral research careers”.

July 2017: Sarah was awarded the SANCOR (South African Network for Coastal and Oceanic Research) Young Researcher Award at the 2017 South African Marine Sciences Symposium that takes place every three years.

July 2017: Sarah was named one of the Top 200 Young South Africans of 2017.

July 2017: We participated in the 2017 SEAmester cruise. Sarah led the “Oceans in a Changing Climate” stream, and Heather, Ruan, and Robyn came along to do science. UCT has a news article about it here.

June 2017: We participated in a cruise to the winter Southern Ocean marginal ice zone, with the goal of collecting ice samples to measure for biogeochemical parameters.

April 2017: Sarah has been awarded the Claude Leon Merit Award for Early-Career Researchers. See the UCT news article here.
