Science and Discovery

Due to hazardous winter weather conditions, SURF will transition to an “essential personnel only” operations mode starting at 5:00PM MT today (Monday, Feb 24). At this time, we plan to return to normal operations tomorrow at 5:00PM MT (Tuesday, Feb 25). Normal day shift operations are cancelled for Tuesday.Due to hazardous winter weather conditions, SURF will transition to an “essential personnel only” operations mode starting at 5:00PM MT today (Monday, Feb 24).
