Whitley Strieber, whose 1987 book Communion did so much to make intergalactic grey dwarves a subject of dinner-table chatter in even the best-regulated households, is clearly a man prepared to entertain many rare and unusual ideas. Visitors to his website may sample the kinds of things that fascinate Strieber, and will find this cogitation:

Between 1962 and 1979 the NSF [National Science Foundation] Polar Research Vessel Eltanin surveyed Antarctic waters, studying the ocean and ocean bottom. In 1964, the ship photographed an unusual object at a depth of 13,500 feet [4,115m]. At the time, there was no submarine that could have carried a piece of technology to this depth.

The object appears to be a pole rising from the ocean floor with twelve spokes radiating from it, each ending in a sphere.
