Taken a little further, I've wondered if dolphins could share a mental awareness of scenes and incidents that span the world and possibly time too.
Orcas more than any other sea creatures scare the # out of me.

I've thought this for, probably, twenty years although it wasn't in the context of holograms. Hypothetically, a dolphin that's echolocated a shoal of fish in the North Atlantic should be able to repeat the impression it received to a dolphin that had never been there.

I'm sure the grants will continue until they can identify enemy submarines by type.
Then it's off to see if they can make dolphins in to suicide bombers.
Science is always for the betterment of humanity, right?
The program first started in 1960 when the Navy studied Notty, a female Pacific white-sided dolphin. The Navy hoped to study the dolphin's biomechanics and then use its findings for developing faster torpedoes. "But quickly the focus changed to covert training," according to NBC.
In additional to being able to detect mines like their American counterparts, Soviet dolphins were allegedly trained to attack divers with harpoons or knives attached to their backs. They also acted as marine kamikazes carrying mines that would rub up on the keels of enemy vessels. "Those dolphins could even distinguish between the sound of the propeller of foreign submarine and a Soviet one," according to Viktor Baranets, who worked in the Soviet military.
In what is easily one of the stranger twists in the military takeover of Crimea, the Russians have seized control of Ukraine's navy dolphin fleet. Yes, dolphins. The annals of dolphin military history is actually teeming with improbable tales, so let this be your guide to the cetacean Cold War.
But, in recent years, Ukraine had shown interest in reviving the program, even announcing in 2012 an ambitious plan to train killer dolphins with knives on their heads. But that never seems to have gotten off the ground because they were planning to disband the dolphin program this April—that is, until the Russians decided to take over, intending to revitalize it. "The work will save unique scientific developments that were abandoned due to Ukraine's reluctance to finance the research in the field," boasted Pravda.

Forgive me for not replying to everyone individually but I found some additional information which may answer many of your questions at the CymaScope website.
The Discovery of Dolphin Language
The precise mechanism concerning how the sonic image is ‘read’ by the cochleae is still unknown but the team’s present hypothesis is that each click-pulse causes the image to momentarily manifest on the basilar and tectorial membranes, thin sheets of tissue situated in the heart of each cochlea. Microscopic cilia connect with the tectorial membrane and ‘read’ the shape of the imprint, creating a composite electrical signal representing the object’s shape. This electrical signal travels to the brain via the cochlea nerve and is interpreted as an image. (The example in the graphic shows a flowerpot.) The team postulates that dolphins are able to perceive stereoscopically with their sound imaging sense. Since the dolphin emits long trains of click-pulses it is believed that it has persistence of sono-pictorial perception, analogous to video playback in which a series of still frames are viewed as moving images.
Reid said, “The CymaScope imaging technique substitutes a circular water membrane for the dolphin's tectorial, gel-like membrane and a camera for the dolphin's brain. We image the sono-picture as it imprints on the surface tension of water, a technique we call ‘bio-cymatic imaging,’ capturing the picture before it expands to the boundary. We think that something similar happens in the dolphin’s cochleae where the sonic image, contained in the reflected click-pulse, travels as a surface acoustic wave along the basilar and tectorial membranes and imprints in an area that relates to the carrier frequency of the click-pulse. With our bio-cymatic imaging technique we believe we see a similar image to that which the dolphin sees when it scans an object with sound. In the flowerpot image the hand of the person holding it can even be seen. The images are rather fuzzy at present but we hope to enhance the technique in future.”
Being largely ignorant of the particulars of dolphin physiology, this answered some of my own questions. Essentially they're saying the water+camera in the CymaScope and membranes+cilia in the dolphin's cochleae are operating on the same principles. I'm honestly still trying to wrap my head around how this works. I'm only familiar with "Cymatics" from seeing demonstrations involving Chladni plates and some of the claims people are making about it seem a bit woo-y. Maybe somebody with the a better understanding of the physics involved would like to weigh in?
