Gliders operated by the Balearic Islands Coastal Observing and Forecasting System (SOCIB) have been deployed in the Ibiza Channel, located in the western Mediterranean Sea (Figure 1). Following a semi-continuous endurance line, gliders have collected temperature and salinity observations along the water column since 2011. Applying the Glider transport toolbox to the delayed-time L1 products, regularly interpolated potential temperature (θ), salinity (S) and geostrophic velocity (GV) are computed for each transect as well as the derived geostrophic transport. This visualization tool provides graphical information about these processed glider data, in particular, vertical sections of θ, S and GV, as well as θ/S diagrams for all individual transects. Also, timeseries of total and water mass geostrophic transports are displayed. Finally, this application gives access to the derived monthly climatologies of the different diagnostics.
