Short summary
This study establishes the local stratigraphy and 3-D aquifer geometry of a submarine groundwater discharge site in the Hanko Peninsula, south Finland. The study is based on a rich dataset of marine seismic profiles, multibeam and side-scan sonar images of the seafloor, and onshore ground-penetrating radar and refraction seismic profiles. The groundwater discharge takes place through metre-scale pockmarks on the seafloor, confirmed by elevated radon concentrations in the overlying water.
