    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.

    The tide gauge of Palma de Mallorca is located in the eastern part of the harbour and it measures the sea level from 1964 to 1966. Note that another station (PSMSL ID 1892) was recording data from 1997 onwards in a near location.

    The viewer allows to visualize interactively the zooplankton biomass data obtained monthly in the RADIALES cruises (called RADCAN or RCAN cruises for those carried out since 2013). The layout displays a sidebar, where you can select the desired option for a series of variables (station, size fraction, year, plot type, …) and a main panel where the graphs are displayed. It is organized in three tabs: [1] ‘Plot’ displays data from one single station (the complete list of the stations, as well as their map and the geographic coordinates, are in https://seriestemporales-ieo.net). [2] ‘multipanel’ lays out together in the same figure the individual plots of all the stations, allowing for comparison among them. [3] ‘Sampling dates’ shows graphically the months, from the starting of the project, with zooplankton biomass data available.

    Cartographic viewer that displays the data of fishing discards collected by scientific observers on board commercial vessels. The units refer to the amount of fish (Kg) that is discarded per hour of fishing or by fishinng trip in the case of fixed gear.

    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.

    The tidal gauge of Algeciras is located at the harbour and it measures sea level from November 2006 onwards. This station is a replacement gauge for the former Algeciras tide gauge (PSMSL ID 490) with records from 1943 to 2002.

    In 2013, the Instituto Español de Oceanografía (IEO) developed a maritime data downstream service (http://playas.ieo.es) particularly focused on providing sea surface temperature (SST) at Iberian Atlantic beaches, a parameter that, although basic for the scientific community, it was certainly rather unusual in those weather forecast reports to the wider public. Thus, although the web-service enhances the visualization of SST at more than one thousand beaches, it also provides 3-day forecast of a set of other meteo-ocean variables (air temperature, wind speed and direction, wave height, period and direction, and tides).
