Inter-annual variability of the upwelling system off Cap Blanc studied from 18 years time series export flux of dinoflagellate cyst

The upwelling system off Cap Blanc forms one of the most productive region in the world. Permanent upwelling bearing nutrient rich water and mineral dust input from Sahara fertilize this coastal area as such, it becomes a key area in the global carbon cycle. In the scope of current global climate change, it is crucial to obtain insight into the effects of this change on the Cap Blanc ecosystem. This can be achieved by monitoring the production and association composition of key organisms of this ecosystem representing different trophic levels.

Dinoflagellates as marine planktonic organisms are a useful tool to study the dynamic of upwelling system off Cap Blanc because they consist of both photo- and heterotrophic organisms. Here we studied the export production of dinoflagellate cysts over an 18 years period by analyzing materials collected by a sediment trap located under the upwelling filament track of the major Cap Blanc upwelling cell at a depth ~1300m.
