The estimation of air-sea CO2 fluxes is largely dependent on wind speed through the gas transfer velocity parameterization. This sketch visualizes this estimation by using data obtained on board an opportunity vessel that transported Citröen cars from/to Vigo (Spain) to/from Saint Nazaire (France), from October 2002 to July 2003. You can explore the spatio-temporal variability of the CO2 flux along the route. Moreover, you can examine the differences in the estimation when a different wind speed source is selected or the algorithm employed to perform the estimation is modified.

Operational configuration of ROMS (Regional Ocean Modeling System) off NorthWest Iberia. In this configuration, two grids are nested during online execution. Data from the coarser (4 km horizontal resolution) 236 x 181 grid force the lateral open boundaries of the finer (~1.3 km) 312 x 167 embedded grid. Outputs at hourly and daily temporal resolution.

The northern "Contourite Depositional System" located within the Gulf of Cadiz is well studied and was drilled last year during IODP expedition 339. We aim to acquire 3 additional seismic lines over these drill sites towards the shallow shelf for sequence stratigraphic studies and acquire a connection profile to the southern part of the Gulf, along the Moroccan margin. The research along the Moroccan margin builds upon previous investigations (R/V Belgica 2002, 2005, 2008) and will focus on smaller current-related deposits in order to fully understand the hydro- and sediment dynamic picture of this area during the past 2.4 Ma. This will allow to better assess the evolution of cold-water coral ecosystems. This will be achieved by gathering additional seismic lines and perform hydrographic measurements. In the second half of June, several cores will be gathered from the southern part of the Gulf of Cadiz with the R/V Marion Dufresne. In order to visualize the subsurface of these core sites, 6 seismic profiles will be gathered, connecting these core sites.
