Multi-sensor acoustic evidence of submarine volcanism across diverse tecto-volcanic regimes ...
Submarine volcanism and associated submarine venting can be observed using multibeam bathymetry, seafloor backscatter, water-column backscatter, and sub-bottom acoustic profiling. While numerous volcanically-driven gas accumulation and venting phenomena can be observed through these techniques (such...
