SUBMARINE CABLES AND PIPELINES
Mariners are advised not to anchor or trawl in the vicinity of submarine cables and pipelines. Pipelines are not always 
buried and their presence may significantly reduce the charted depth. They may also span seabed undulations and 
cause fishing gear to become irrecoverably snagged, putting a vessel in severe danger.
