MEWO S.A. carried out a geophysical survey campaign for the Baltica 1 offshore wind farm site and its connection corridor. The work used acoustic, seismic and magnetic methods (including side scan sonar, multibeam echo sounder, sub-bottom profiling and sparker seismic surveys) to image seabed features and shallow subsurface conditions, supporting environmental assessment and informing preliminary engineering decisions for turbine layout and cable routing.
