Overturning Circulation and Carbon storagE in the Atlantic North

'Working to unpuzzle ocean carbon pump variability'

OCCEAN's research focus involves exploring the drivers of variability of the anthropogenically mobilized CO₂ storage in the North Atlantic by providing a relevant, plausible and physically consistent high-time-resolution framework of CO₂ variability. 

Some aspects I want to contibute to within the OCCEAN's framework are:

1) To feed and extend observational databases (e.g. GOSHIP, GLODAP, SOCAT, BGC-Argo).

2) To identify key hotspot locations to carry out observational fieldwork (e.g. hydrographic-cruise or mooring based). 

3) To integrate the latest technological advances (BGC-Argo, gliders, sensors on moorings) to build up a high-temporal observation-based 'view' of the contemporary ocean, which leads to improving the assessment and prediction of the ocean carbon upkate, transport, and storage, and reduce the uncertainties of the annual means.

4) To explore the drivers of variability of the carbon inventory (storage) in the North Atlantic in relation to the Meridional Overturning Circulation (MOC), and to tackle ongoing trends.

5) To explore the linkage between MOC variability and the varying contribution of the physical and biological carbon pumps.

6) To compare indirect high-temporal estimates of the air-sea CO₂ exchange with SOCAT air-sea pCO₂ data.

7) To address the mechanisms involved in the physical drivers of the carbon pump by means of model output data.

8) To be closely involved in the study of ocean acidification, anthropogenic carbon trends, and water mass transformation and mixing in the North Atlantic.
