Why people live in Antarctica for long periods of time?

While there are scientific research stations in Antarctica where people may reside for extended periods, there are no permanent resident settlements or cities. It's true that scientists, expedition staff, and support personnel spend varying durations at these Antarctic stations for research purposes, but they rotate in and out on shifts typically lasting a few weeks up to a year depending on the specific program.. The harsh environmental conditions, geographical remoteness, and international treaties limit long-term habitation in Antarctica to scientific endeavors and temporary work assignments during expeditions and research projects.
