In brief

Hi there, my name is Jens and I’m a biogeochemist studying the ocean carbon cycle through measurements of CO2 in seawater. Since 2020, I’m working as a PostDoc with Nicolas Gruber at ETH Zurich. We use global ship-based observations to reconstruct the accumulation of CO2 in the global ocean, and how this drives acidification in the ocean interior. This work profits from the experience gained during my PhD, specifically the development of pH analytics, the analysis of autonomous pCO2 measurements from a voluntary observing ship and several months spent at sea. As a coordinator of RECCAP2 - the second cycle of the REgional Carbon Cycle Assessment and Processes project - I’m working with an international board of around 100 scientists covering a broad view on the ocean carbon sink through models and surface flux estimates.
