Under the Pacific Ocean waters off California’s Big Sur coastline, a group of scientists have sent a robot to observe sizable cavities in the seabed. Things, however, aren’t going quite as planned. The automated machine has, indeed, detected holes at the bottom of the sea, but their precise nature is surprising. And on top of that, it seems that they’ve emerged for a deeply troubling reason.
This particular area of the seafloor has been designated as a pockmark field – a reference to the large dents which define it. The place, in fact, has been referred to as the largest pockmark field in all of North America. Apparently, evidence for the cavities first emerged back in 1999, but they puzzled scientists for many years after.
