Ocean Observing and Tracers

Air-sea exchange at the surface injects substances important for chemistry and life below the surface, like oxygen and carbon, into the water. Ocean ventilation and circulation are processes that transports surface waters to the interior ocean, and back up again. By observing tracer compounds we can characterize the time-scale and magnitude of ventilation, and understand the processes that are important for ocean life, ocean dynamics, and to understand climate change. 

Specific research interests are:

  • Ocean ventilation and circulation
  • Deliberate tracer release experiments
  • Exploring novel transient tracers
  • Innovations for sustained interdisciplinary ocean observing
  • Ocean citizen science


The working group is involved in different projects. Current ones are: 

  • EuroSea – Improving and Integrating European Ocean Observing and Forecasting Systems for sustainable use of the Ocean 


  • AtlantOS - Optimising and Enhancing the Integrated Atlantic Ocean Observing Systems
