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.
