Description
Summary:This data release includes 56,432 square kilometers of multibeam swath bathymetry collected during a 2017 (June - August) research expedition onboard the RRS Discovery, DY081, in the North Atlantic Ocean. DY081 was the first fieldwork component of a European Research Council funded project, ICY-LAB, led by Dr. K. Hendry from the University of Bristol to study nutrient cycling in the North Atlantic. Four sites of interest were surveyed with an EM-122 echosounder prior to scientific operations, such as CTD deployment, sediment coring, and/or ROV dives. The four sites were Orphan Knoll off the coast of Newfoundland, and Nuuk, Nasrsaq, and Cape Farewell off southwest Greenland. Multibeam data was also recorded and processed during transit between locations. Data from the study sites and transits (EM-122 raw .all files and 25-meter resolution grids) are provided. ...
