Group structure and its development in an isolated and confined environment.

An Antarctic winter-over has been regarded as one of the analogue situations in long-term space flight, especially from the aspect of prolonged isolation and a confined environment. Thus, Antarctic winter-overs at research stations offer us a unique opportunity to observe the dynamics of group and individual behavior. This research examines group structure and its development during long-term isolation and confinement in an Antarctic research station using direct, quantitative observations.
