This month’s newsletter is devoted to the Mediterranean Sea and its various faces.
As an introduction, an article by Drobinski et al. presents the HYMEX program (HYdrological cycle in Mediterranean Experiment) which is aiming at better understanding the global water cycle in the Mediterranean region. The next article by
Langlais et al. is dealing with a high resolution coastal and shelf model in the Gulf of Lions. Then, Boy et al. are describing the input from spatial gravimetry to better represent the ocean circulation in the Mediterranean Sea. The next article by D’Ovidio et al. is telling us about tracer frontal structures induced by altimeter velocities with a lagrangian technique in the Eastern Mediterranean Sea. The last article by L’Hévéder et al. is dealing with operational forecast of glider trajectories in the
Mediterranean Sea using the Mercator forecasts.
