I am looking for bathymetry data for European seas, and in particular for the Mediterranean see. Those datasets seem to exist (I could find some maps of bathymetry) but I would like to have the raw information (depth) and not the coloured maps. Raster or vector formats are OK, but I prefer raster.

Are you looking for maps with isolines ("isobathes")? Probably some formats available for download on the EMODnet Portal will be suitable for you (using appropriate software).

You could also download an XYZ file.

The Global roughly 1km topography and bathymetry data here
includes the Mediterranean Sea region. The website has tools for download regions as well as the entire global set. The data is available for download as a large single file (for the globe). The site also has links to interactive pages that can be used to select sub-regions for download.
