In the wake of Hurricane Sandy on one side of the world is the gradual disappearance from maps of Sandy Island (Sable Isle in French, apparently) on the other side of the world. Richard Chirgwin notes that amateur radio "DXers" had concluded a decade ago that there was no good evidence for the island's existence.
Seeing that navigation charts claimed depths of 1400 m at the location of the supposed island, Dr. Maria Seton of the University of Sydney directed the research ship she was on to travel right over the coordinates of the island, and the popular press has taken this as proof that there never was or will be a Sandy Island.
A tumblr.com site excerpts maps which cover the area in question. While popular accounts state that even modern navigational charts include this island, no examples seem to be readily apparent.
