The ocean contains by far more carbon than the atmosphere and terrestrial biosphere. It is therefore a key component of the global carbon cycle. Due to its chemistry, the marine inorganic carbon system has a huge uptake capacity for man-made carbon dioxide which helps to strongly mitigate climate change. We therefore need to understand and monitor the changing marine carbon cycle and how it affects climate, marine environment and life.
Specific research interests are:
Marine Carbon Cycle – natural processes and anthropogenic perturbation
Dynamics and Trends of the Marine Oxygen Cycle
Chemical method/sensor development and evaluation
New approaches in autonomous ocean observation
Projects
MOSES – Modular Observation Solutions for Earth Systems
REEBUS – Role of Eddies in the Carbon Pump of Eastern Boundary Upwelling Systems
C-SCOPE – Towards Marine Carbon Observations 2.0: Socializing, COnnecting, Perfecting and Expanding
