With my group, I study a #CDR method of artificially increasing ocean C-sink by adding alkalinity.

In an #EarthSystemModel
large amounts of alkalinity boost the oceans' capacity to absorb CO2.
This comes at a price of unprecedented perturbations in #biogeochemistry with unknown implications for marine life.

How does Earth breathes CO2 under different #ClimateChange scenarios?

Have a look at this visualization showing seasonal variations of atmospheric CO2 modulated by anthropogenic emissions and the strength of the ocean and land carbon sinks.

Computed with an #EarthSystemModel #MPI-ESM.

Exciting news :thinkhappy: 📰

Our #manuscript presenting an application of coarse-grained component #concurrency for #ocean #biogeochemistry has been accepted for publication.

Let me #decipher what this is 🤯

In an #EarthSystemModel, the #uptake and #storage of #CO2 in the #ocean is computed by the embedded ocean #biogeochemistry models. 1/

@MPI_Meteo

It is challenging to represent the #CoastalOcean #CarbonCycle in an #EarthSystemModel.

Due to a relatively coarse spatial resolution, #global models do not resolve the complex coastal #biogeochemical dynamics. #Regional models don't get the open-coastal ocean exchange at their boundaries.

Find out how we address this challenge with a telescoping #HighResolution #model:
