Back in December 2018, iXblue Sonar Systems Division (SSD) and University of Saint-Andrews conducted up to 11 km of near-surface geophysical investigation in shallow water environments (< 25 m) in Scotland shorelines using the Echoes 10 000 (10 kHz).
High-resolution seismic profiles show individual and parabolic reflective objects that correspond to pluri-centimetric rocks visible in sediment cores. This unique performance is due to home-made skills of designing efficient CHIRP technology with large transducer beams (around 20°) that results in an impressive signal continuity and the identification of buried objects. This key performance brings new insights for 3D mapping of individual boulder clearance for shallow marine environment (< 150 m).
