A vast deep-sea canyon has been mapped off the edge of the Kerry coast.
The submarine canyon which is 3,000 metres deep has been mapped some 320 kilometres west of Dingle.
A team of UCC led scientists aboard the State research ship RV Celtic Explorer have mapped the canyon during a research expedition.
Ten Eiffel Towers could be stacked within the canyon which has near-vertical 700m deep cliffs in places according to today’s Irish Examiner.
Such canyons are rapid routes for pumping CO2 deep into the ocean where it is safely stored away.
