Where: Online via Zoom

ABSTRACT
We will begin by looking at INFOMAR, the successor to the Irish National Seabed Survey, and the importance of seabed mapping for an island nation, before investigating a variety of seafloor features and shipwrecks from around the Irish coast. We’ll then look at the seafloor from a global perspective, focusing on the work of GEBCO (General Bathymetric Chart of the Oceans) and their collaborative project with the Nippon Foundation to produce, by 2030, the first full bathymetry map of the ocean seafloor (Seabed2030). We’ll finish with a look at a major data contributor to Seabed2030, the Five Deeps Expedition. This took place in 2019 and involved crewed descents via submarine to the deepest points of the world’s five oceans.
