Arctia Meritaito, a subsidiary of Arctia, was contracted by the Norwegian Mapping Authority’s Hydrographic Service (NHS) to carry out a hydrographic seabed survey of the planned Sørvest F offshore wind area in the Norwegian North Sea under the MAREANO programme. The scope included seabed mapping using a multibeam echosounder and a sub-bottom profiler to survey depth/topography and subsurface conditions relevant to area characterisation. The work was planned to be executed using the multipurpose research vessel MPV Pohjanmeri, with the offshore campaign expected to run over the summer season.
