| Definition | An acoustic towfish developed by the British Antarctic Survey, built to carry a set of transducers (38 kHz split beam, 120 kHz split beam, 200 kHz single beam) and to be towed in 20 m to 30 m depth. This instrument was design to sample in the 'blanking zone' of ship-mounted echosounders, an area in the water column where air bubbles and acoustic noise corrupt the echosounder's measurements. | ||
