Dr Matthieu Bressac is a Postdoctoral Research Fellow at the Institute for Marine and Antarctic Studies. His research focuses on carbon and iron biogeochemistry, and combines field and laboratory works to explore how these two elements are recycled in the mesopelagic zone (100-1000 m).
Dr Bressac graduated in 2013 with a PhD in Biogeochemical Oceanography at the University Pierre et Marie Curie (Paris VI, France). His thesis focused on the impacts of dust deposition on the ocean iron cycle and carbon export. He then worked as a Postdoctoral Fellow at the International Atomic Energy Agency Marine Environment Laboratories (IAEA-MEL, Monaco) to develop new techniques for the analysis of radionuclides in seawater. Between 2014 and 2017, Dr Bressac was awarded a Marie Curie Postdoctoral Fellowship and worked at the Institute for Marine and Antarctic Studies (IMAS, Australia) and at the Laboratory of Oceanography of Villefranche (LOV, France) to investigate the implications of the mesopelagic remineralization for the ocean iron cycle.

Matthieu’s research aligns to the University’s research theme of Marine, Antarctic and Maritime. His research interests include carbon and iron biogeochemistry, and in particular the fate of these elements in the mesopelagic (100-1000 m). Notably, Matthieu has developed a new instrument able to measure the bacterial remineralization of particulate iron at in situ pressure and temperature conditions. This instrument has been successfully deployed within the upper mesopelagic (100-200 m) of the Subantarctic Zone and Mediterranean Sea.
Matthieu is currently involved in four international projects which aim at better understanding the factors controlling the biological carbon pump, and in particular the export of carbon to the deep ocean. These projects involve collaboration with scientists from the US, France, and Australia.
