At frequencies audible to humans (20 Hertz to 20,000 Hertz) the sound-bubble form dominates above 20,000 Hertz the shape of sound becomes increasingly beam shaped, similar to a lighthouse beam in appearance. The holographic aspect stems from the physics theory that even a single molecule of air or water carries all the information that describes the qualities and intensity of a given sound. The team has recognized that sound does not travel in waves, as is popularly believed, but in expanding holographic bubbles and beams. The CymaScope provides our first glimpse into what the dolphins might be ‘seeing’ with their sounds.” Kassewitz, of the Florida-based dolphin communication research project said, “There is strong evidence that dolphins are able to ‘see’ with sound, much like humans use ultrasound to see an unborn child in the mother’s womb. Now that dolphin chirps, click-trains and whistles can be converted into CymaGlyphs, we have an important tool for deciphering their meaning." ![]() The CymaGlyphs produced on the CymaScope can be likened to the hieroglyphs of the Rosetta Stone. "Jean-Francois Champollion and Thomas Young used the Rosetta Stone to discover key elements of the primer that allowed the Egyptian language to be deciphered. Reid said that the technique has similarities to deciphering Egyptian hieroglyphs. CymaGlyph patterns may resemble what the creatures perceive from their own returning sound beams and from the sound beams of other dolphins. The CymaScope has the ability to visualize dimensional structure within sound. Within the field of cetacean research, theory states that dolphins have evolved the ability to translate dimensional information from their echolocation sonic beam. The CymaScope captures actual sound vibrations imprinted in the dolphin’s natural environment-water, revealing the intricate visual details of dolphin sounds for the first time. Previous techniques, using the spectrograph, display cetacean (dolphins, whales and porpoises) sounds only as graphs of frequency and amplitude. The National Oceanic and Atmospheric Administration (NOAA) recommends that boaters and paddlers maintain at least 50 yards away from dolphins and at least 300 – 400 yards away from killer whales to give them room to feed, travel, and stay together.Left: cymaglyph of adult dolphin voice, Right: cymaglyph of a baby dolphin calling to its motherĬertain sounds made by dolphins have long been suspected to represent language but the complexity of the sounds has made their analysis difficult. Remember that dolphins are protected by the Marine Mammal Protection Act. Email reports of sightings to David Anderson or call Cascadia’s office at 36. These can help identify individual animals and to monitor their overall body condition. Pictures and videos are appreciated, especially if they are in focus and have enough detail to identify the species or to see marks or nicks on the animal’s fins or bodies. We are interested in tracking the presence, behavior, and condition of these animals. If you see unusual marine mammal species, please contact Cascadia Research. Many of these species, except for the harbor porpoise, are not commonly sighted in Puget Sound. It combines information about distinguishing features and video clips of six marine mammal species including harbor porpoise, common dolphins, bottlenose dolphins, Dall’s porpoise, Pacific white-sided dolphins, and killer whales. We have created this short video to help people identify which species they are seeing. Sightings of common dolphins and bottlenose dolphins have increased considerably since 2016 and Pacific white-sided dolphins are seen from time to time.Ī few species of animals can look a lot like a dolphin, especially from a distance. Harbor porpoise returned to the Puget Sound around 2000, and sightings of several dolphin species have been increasing since 2010. In the late 20th century, the only small cetaceans you were likely to see in the Puget Sound were Dall’s porpoise. ![]()
