In the #RECCAP Southern Ocean chapter we looked at how the ocean bgc models reproduce recent temperature trends and thermal effects on air-sea CO2 fluxes and the forced ocean models do fine...

One of the #RECCAP chapters where I learned most 🔽
e.g.
"The seasonal amplitude of the CO2 flux is 50%–100% larger in the models at mid-latitudes (despite having a similar phasing, i.e., stronger sink in winter and spring)."

Knowing about the specific biases is necessary to improve them.

#RECCAP global coastal ocean carbon sink chapter published, led by Laure Resplandy:

doi.org/10.1029/2023...

The chapter includes budgets for methane and nitrous oxide and concludes: Coastal nitrous oxide and methane emissions offset 30%–60% of the CO₂ coastal uptake in the net radiative balance.

Time for a first post today as the #RECCAP #Southern Ocean chapter came out today - only four years and seven months after the first #RECCAP2 meeting in Gotemba!

We characterise the carbon sink in terms of mean, seasonal cycle, trends and storage.
