   COMMENTS:  AWS 8919 WAS PLACED AT THE SPINE SITE ON THE ANTARCTIC PENINSULA JUST EAST OF ROTHERA.  ON MARCH 20, 1983 THE STATION WENT OFF THE AIR.  IT HAS SINCE RESUMED DATA TRANSMISSION, BUT IT APPEARS AS IF THE TOWER HAS BLOWN OVER.  A NEW UW VERSION AWS IS PLANNED FOR AS 84/85.  IT WILL BE DEPLOYED BY THE BRITISH ANTARCTIC SURVEY.
