A Floating Instrument Platform (FLIP) ship is a floating instrument platform and manned research vessel that is 355 feet long. The FLIP has been widely used to study the acoustics of whales and other marine mammals, the effects of seismic waves on the water, and heat exchange between the atmosphere and the ocean. It works by being towed out to sea and having one end submerged. The instruments and crew are located in a portion of the ship that remains above the surface of the ocean. This giant ship is most impressive.
