doi:10.1126/science.aab2620, 2015
My greatest achievement thus far was the creation of a neural network-based reconstruction (SOM-FFN) of the air-sea CO2 flux over the past decades (see also Landschützer et al 2013, 2014, 2016). This work formed the baseline for the discovery that the Southern Ocean carbon sink is more variable than previously recognised.

Landschützer, P., Laruelle, G. G., Roobaert, A., and Regnier, P.: A uniform pCO2 climatology
combining open and coastal oceans, Earth Syst. Sci. Data, 12, 2537–2553,
I integrated open ocean and coastal ocean surface ocean pCO2 estimates providing the baseline for the climatological reconstruction of the sea surface pCO2 over the full aquatic continuum.

doi:10.1038/s41558-017-0057-x, 2018
I provided the first global-scale observational evidence of a long-standing model prediction, namely that changes in carbonate chemistry and warming led to an increase in the seasonal cycle of the sea surface partial pressure of CO2 over the past 34 years.

Since 2018, I am working with professional sailboat racers to fill measurement gaps in the Southern Ocean. This is a novel and cost-effective way to strengthen the observing system in the Southern Hemisphere and complement shipboard and autonomous observing platforms.

In my group we expanded the SOM-FFN neural network method we applied to map the surface ocean partial pressure of CO2 to also map the interior distribution of dissolved inorganic carbon (MOBO-DIC). This work is a first step towards closing the carbon budget from the air-sea interface towards the deep ocean.

In my group we are working on better representing and quantifying uncertainties in air-sea CO2 flux reconstructions. In this study we could show that we have regionally varying dominance of uncertainty from pCO2 interpolations, wind and transfer velocity.

Since 2018 I am working with professional sailboat racers to fill measurement gaps in the Global Ocean. In this study my group could show that these measurements made from sailboats have a significant effect on the regional air-sea CO2 exchange in the North Atlantic and Southern Ocean. This effect is however only detectable when measurements are of high accuracy and unbiased.

In this study my group could show that an ensemble of sea surface partial pressure of CO2 reconstructions agree on decadal fluctuations in the Southern Ocean. Furthermore we could show that there is no clear relation to the interpolation method used.
