For several years the ship alternated with the Dutch weather ship ''Cumulus'' to staff station M. From 1986 on ''Polarfront'' staffed station M alone. Each month ''Polarfront'' left the station for one to two days to take on a new crew and new supplies. Once a year, usually in early October, the ship stayed in its home port for a week to carry out maintenance.
