Research Stations Are A Bit Like Mining Towns
Mining towns emerged in history as a means of housing a large population that moved to an area to work in a mine that had just been opened. Many of the workers left behind their families, as conditions were too difficult for women and children. Many people lived in tents, and there were very few opportunities for entertainment.
Researchers in Antarctica have some free time, during which they may go to the coffee shop or bar at their station. They may even play trivia or watch a movie together. Nevertheless, everyone is living in a temporary situation, so all of the researchers know that their time together and the relationships that they form are temporary. Furthermore, no children are allowed, so many have to leave their families behind.
