Buried tunnel valleys, developed by glacial meltwater below former continental ice-sheets, are often hardly recognisable during deep land seismic surveys and may act as obstructions in the investigation of deeper geological strata both onshore and offshore. Unique, detailed high-resolution onshore s...
