The effectionately-called 'Shark of Science' is a multiple hydrophone array with 16 hydrophones spanning
the water column in the vertical and 32 phones laying along the bottom in the horizontal. During an experiment
100 miles off the coast of New Jersey we often picked up bottlenose dolphin clicks and whistles.
