A hydrophonic native Ambisonic B Format microphone is being developed by Prof Tony Myatt, University of Surrey, and a team of researchers from Europe. This small (1m) array of hydrophones will capture holistic surround sound environments that can be reproduced using standard Ambisonic reproduction technology. Sounds recorded using this method capture entire soundfields and a sounding objects, not reducing a sound source (which might be the size of a blue whale) to a single point of sound as traditional microphones do, but capturing the spatial distribution of sounds and resonances, entire sound objects and the movement of sound sources.
