    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.

    This sketch visualizes the exposure of the Euroregion Galicia (Spain) - North Portugal coasts to potential oil spills coming from the Finisterre Traffic Separation Scheme. These navigation corridors are used by ~40,000 ships per year, and more than 30% of these vessels transport dangerous substances. Results summarize conditions during 2012 and were obtained by running 8,868 lagrangian simulations. In each simulation 2,345 virtual particles were deployed and followed during the next 96 hours. Particles were transported by sea surface currents obtained from a realistic high resolution ocean model and also dragged by the wind. The four corridors that integrate the traffic scheme and the approaching regions are shown. The number over the corridor is the total probability of reaching the coast during the first, second, third or fourth day after the spill. Circles along the coastline are the probability of arriving that specific region. Setting the mouse pointer over one corridor, you can filter the data to get a much simpler visualization.

    Studying the Messinian Salinity Crisis on the Balearic promontory and using its markers to assess post-crisis vertical movement and the reactivation of the region. 1) Fine-scale continuous mapping of evaporites from land to the deep basin in order to answer the following question: What is the spatial-temporal variability of evaporites of the Balearic Promontory (evaporites on land, very thin or thick evaporates at sea)? 2) Using the Messinian as a marker of syn- and post-MSC deformations; isolating recent movements from previous deformations and quantifying them in order to reproduce the paleo-bathymetry and paleo-connections during the crisis. Were the evaporites in shallow basins continuous with evaporites in deeper basins before the recent deformations? The related project is 'Action Marges', Mediterranean study site.

    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.
