4 Under The Sea The Irish national research vessel the RV Celtic Explorer has been playing host to a cohort of Irish, Canadian, American, and Portuguese scientists, intent on mapping the Atlantic seabed. Using the latest multibeam echo sounder technology, an extensive 140km long seabed mountain ridge has been imaged along a major fracture zone associated with the opening of the Atlantic Ocean. Valleys through this fracture zone now form the only North Atlantic passage for deep water species to migrate between the west and east Atlantic. http://www.infomar.ie/StoryMaps/Atlantic/index.html
