Carbon in the twilight zone
COMICS studied how carbon moves through the ocean’s ‘twilight zone’, the area between 100m and 1000m below the surface. This zone plays a key role in regulating atmospheric CO2 levels.

My research interests are marine biogeochemistry and ecosystems; I enjoy taking an interdisciplinary approach to understand the complexities of ocean environments. I am particularly interested in the oceanography of Polar Regions due to the vital role they play in the changing global climate.
Currently I am working with the SCOOBIES project (https://www.bas.ac.uk/project/scoobies/) looking at the biogeochemical fluxes near South Georgia and supporting the long term mooring.
