The Seabed

New series. Aoibhinn Ní Shúilleabháin, Kathriona Devereux and Jonathan McCrea examine more of the science behind a variety of topics, beginning with a look at the oceans. Kathriona meets Charise McKeon of the Geological Survey Ireland, who is using sonar-imaging technologies to map shipwrecks and help maintain, preserve and protect Ireland's maritime heritage.
