How's this? Apart from using the proposed DCAT for services predicates, I made two significant changes:
1. The EEA catalog endpoint is a `dcat:DiscoveryService` (and thus is both a `dcat:Catalog` and a `dcat:DataService`). Not sure if the former actually applies though. 
2. I replaced your URI for the service with its actual URI. 

The second point will clearly need a discussion. In @andrea-perego's original (above) the service-description has a separate URI. I'm suggesting that the actual URI should be used, since the descriptor properties really are associated with that thing. I also added a new proposed property `dcat:endPoint` which is kinda comparable to the dcat:Distribution/dcat:accessURL property.
