Hopefully this isn't so far afield as to get banned - apologies in advance to those who think it doesn't belong.
This article discusses a region of Antarctica which is described as "West Antarctica". However, Antarctica is a roughly circular mass centered on the South Pole. Hence any boundary region is north of the center of mass. I suspect there's a convention for naming a region with a compass direction, perhaps relating to the prime meridian or some such, but I can't find information on this. It's just a matter of curiosity, but I would like to know how the region in question comes to be "west".
