An underwater leak detection apparatus (100) comprises a housing (102) having a plane intersecting a pitch axis and a roll axis of the housing (102), a transducer (104) arranged to ensonify a volume of a first fluid, at least two sensor elements (108) substantially upstanding with respect to the plane and arranged to generate, when in use, respective signals comprising data in respect of the at least two sensor elements (108), and a processing resource (200) operably coupled to the at least two sensor elements (108), the processing resource (200) being arranged to support a correlator (304) and a leak detection module (310). The correlator (304) is arranged to receive the signal and to correlate the data in respect of the at least two sensor elements (108), thereby generating correlation output data. The leak detection module (310) is arranged to analyse the correlation output data in respect of the at least two sensor elements (108) and identify data of the correlation output data indicative of a presence of a substantially elongate volume of a second fluid in the ensonified volume of the first fluid. The leak detection module (310) is further arranged to generate an alert signal in response to identification of the data indicative of the presence of the substantially elongate volume of the second fluid.
