“…High-resolution chirpesonar profiles were acquired with a Teledyne Benthos Chirp-III SBP system, composed by a 16 hull-mounted transducer array, using a 2e7 kHz sweep-modulated bandwidth, which allowed a vertical resolution on the order of 50 cm. Seismic profiles were post-processed and visualized with SeisPrho (Gasperini and Stanghellini, 2009). Bottom sampling was performed using a large volume Van Veen Grab (60 l), heavy dredge and a gravity corer of 1.2 tons (Table 1).…”
