Does Antarctica have the most ghosts of any continent? On a per capita basis, the answer is yes. While the South Pole and environs doesn’t have a permanent population, there are on average 2,500 people living there during the year -- approximately 4000 in summer and 1000 incredibly hardy ones in winter (source). While no complete necrologies exists for the Antarctic, at least 268 people have died there since humanity first decided it was a good place to visit. So if the ghosts divvie the work evenly, each one only has to haunt 9.68992 inhabitants.
Abandonments can be amazing to visit, but are all the more fascinating when they are located on the edges of the known world. One of the things that sets antarctic abandonments apart from other abandoned towns and cities is the fact that the remoteness of their location keeps them preserved like few places in populated regions ever are - providing a frozen-in-time (forgive the pun) picture of what life was like when their inhabitants left or perished in the cold.
