Irish Shelf Seabed Geomorphological Map v2023

DatasetNational · Ireland

Dataset present a high-resolution (up to 10 m/ pixel) seabed geomorphology map of the entire Irish continental shelf, up to a depth of 200 m below sea level (bsl). The map was produced taking advantage of the high resolution Irish National Seabed Survey (INSS) and INFOMAR multibeam dataset, and u...
