This survey has as goal the acquisition of geophysical data and grab samples for the assessment of marine archaeology, environmental and geotechnical investigations and site information for tendering purposes.
The project is the implementation of a Danish Parliament initiative for establishing offshore energy infrastructure in the Danish North Sea and in the Danish Baltic Sea to connect respectively 3 GW and 2 GW offshore wind energy to the mainland and to neighboring countries via offshore energy hubs.
GEOxyz’s contract in this ambitious project corresponds to the Baltic Sea component which, in meantime has also increased from 2GW to 3GW. The geophysical scope includes 2D UHR (ultra-high resolution) seismic, a high-resolution magnetometry box survey, and a high-resolution acoustic survey (multibeam echo sounder and dual-frequency side scan sonar). The box survey, as the name suggests, are rectangular areas used as input for the assessment of future geotechnical drilling works. The seabed surface was provided both by acoustic surveys (sonar and multibeam) and the sub-seabed geology by SBP and high-resolution seismic. The combination of the methods insures the precision of our data.
