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.

In this Cruise Plan we present a strategically collected suite of sediment coring stations that may help to study fluid flow system in the northern Tunisian margin extending to the Tyrrhenian Sea.

The ECOTRANS oceanographic-fishing cruises will cover the following objectives: i) Sampling plankton (micro and mesozooplankton); ii) Sampling larvae of selected pelagic fish and iii) Trawl sampling (demersal) and bird census to determine the species and functional groups biomass and the trophic ecology of small pelagic fish, hake, monkfish and sharks at the NW Mediterranean ecosystem. The cruise (15 days of duration) will be conducted during the spawning period of the sardine (winter) in order to get their larvae.
