A Sudden Rogue Wave Knocked This Diver Off Course—Her Sonar Revealed Something Impossible

Driven by a mix of dread and professional duty, Marcus grabbed the radio microphone from its brass hook. "Coast Guard, this is research vessel Aura. We are thirty miles offshore and have just recorded a massive underwater displacement and an unidentified moving mass plunging into the abyssal zone."

A wave of loud static crackled through the cabin speaker before an operator responded. "Copy, Aura. Our regional sensors picked up a minor underwater tremor along the continental shelf ten minutes ago. We are dispatching a cutter to your coordinates, but due to heavy weather, it might take three to four hours. Mark your location, pull your gear, and clear out of the area immediately."

Marcus hung up the microphone with a heavy sigh. "Three hours is too long. By the time they get here, whatever it is will be gone." "We can't wait," Aris said, turning to face him. "We have the deep-sea camera rig sitting on the stern deck. If we launch it right now, we can catch up to it before it swims away."
