What are the blue lines? Is that melted ice in rivers and streams?

I’m sure this question has a very obvious answer, but why do all the craters seem to be on only one half?

Enceladus is one of my favourite moons. The southern region (top in this image) has plumes spewing at up to 2200 km/h. Material from these jets supply Saturn's faint E ring. These plumes contain mostly water vapour, with smaller amounts of nitrogen, carbon dioxide, and hydrocarbons, suggesting the moon has a subsurface ocean of liquid water underneath the icy surface.
