Research aims of SOLAS Cruise Discovery 330:
The aim is to determine the hydrodynamics of an upwelling plume off the NW African coast, in order to characterise its impact upon the physical, photochemical and microbiological processes contributing to ocean-atmosphere exchange of biogenic gases.

To determine the role of upwelling on the supply, loss and air-sea exchange of trace and biogenic gases
To determine the photochemical and biological fate of upwelled and recently produced dissolved organic matter and its role in air-sea exchange of climatically important trace gases.
To determine the impact of nutrient enriched upwelled water on the spatial and temporal variability of plankton community structure and activity and resultant influence on biogenic gas flux.
