In summer, stations are at their busiest. Large numbers of scientist and support staff may be on site, field projects are underway, and ships and aircraft arrive regularly with cargo, fuel, and personnel.
In winter, stations become far more isolated. Station populations are reduced, and aircraft and vessel operations may be limited or cease entirely for long periods. The remaining team must keep the station running, maintain equipment and infrastructure, support ongoing scientific observations, and manage daily operations through months without external resupply.
