Submarine canyons are the most prominent morphological features on the Irish seabed. They are tens to hundreds of kilometres long, narrow valleys carved tens to several hundreds of metres deep into the continental margin. They often extend from the shelf break at 200 m water depth all the way down to the lower continental rise at approximately 2,500 m water depth funnelling large volumes of sediment and organic matter from shelf regions to the deep ocean (Fig. 7.1).
