Remove the srs. You have set it on the map already.

Remove height and width, these are handled by OpenLayers.

All your layers are configured as base layers, so I bet you only see the
Batimetria layer. Make the layer an overlay by adding

Remove the redraw() line. mergeNewParams will take care of that.
