Quaternary seismic stratigraphy of northern Spencer Gulf, South Australia
High-resolution continuous seismic reflection profiles of northern Spencer Gulf, which is shallower than 25 m, show seismic discordances and bed reflectors to depths of 20 m below the seafloor. Comparison with vibrocore data indicates a correspondence of seismic discordances with major stratigraphic boundaries, often enhanced by pedogenesis. Holocene marine sediments generally form a thin
