SUBPROJECT - A4

 

Trends and variability of oxygen inventory and supply in eastern boundary oxygen minimum zones

 

The objective of A4 is to understand how oxygen minimum zones (OMZs) are maintained by ocean circulation and what are the scales of temporal variability in OMZs and the physical supply of oxygen to them. It is based on shipboard, glider, and continuous long-term moored observations, on a temporary sub-mesoscale mooring array and process simulations with idealized geometry and forcing. It provides a key reference data set of oxygen and current variability within the Eastern Tropical North Atlantic (ETNA) with relevance for the entire SFB and aims to develop new parameterizations of ventilation processes not resolved in ocean GCMs and coupled ocean-atmosphere GCMs.
