Baltic Sea Underwater Infrastructure Events
The Baltic Sea is traversed by many means of communication and power distribution and by pipelines.[1] These are vulnerable to incidents which might damage them, in particular involving anchoring. There have been multiple incidents which have caused disruption to undersea infrastructure.
