SUMMARY: Diving pods of offshore toothed whales and dolphins (odontoceti) feed on squid above mid-oceanic ridges where they are often exposed to oscillations in ambient water pressure when shallow earthquakes suddenly erupt in the seafloor below them. On rare occasion these changes in pressure are too excessive and/or too rapid to be counterbalanced by the whales' pressure regulating anatomy resulting in barotrauma in the sinuses, air sacs, and middle-ear air cavities of each animal's head. Since intact cranium air spaces play a major role in the function of echo-navigation and echo-location, a pressure related injury in this biosonar system renders the victims unable to use acoustic navigation to determine their position and find food. Nor are they able to dive without suffering intense pain.
The injured pod huddles together for protection against sharks and swims slowly away from the epicenter, but not in a random direction. Since water is 800 times more dense than air, the increased resistance (drag) to swimming against or perpendicular to the surface flow turns the whales headfirst and points them downstream in the path of least drag.
Barotraumatized pods can recover after an unknown period of rest on the surface. Those that do not are eventually: (a) guided to a stranding beach by the surface current, (b) harvested by sharks or killer whales, or (c) die and sink to the bottom.
After about a week on the bottom in water less than 100 meters deep, decomposing gases will form and re-float the carcasses that will then be carried by the surface currents to a beach.
Non-navigating whales, carcasses, flotsam, and sea weeds are all deposited on beaches because the current that carried each grain of sand to build the beach in the first place, is the same energy determining the path of everything floating or swimming blindly on the surface.
Where currents wash shoreward, there are beaches, flotsam, and beached whales; where current does not wash toward the shore, there are no beaches, no flotsam, and no beached whales.

Do whales commit suicide?
researchers do not believe the whales are intending to commit suicide. It is beginning to appear they either get disoriented which could be caused by (a) or (b) or they are attempting to escape something in the water that is causing them distress. Whenever whales are helped back into the water they don't rebeach themselves in the majority of cases which tends to dispel the "suicide" mentality.
