The Great Barrier Reef is deteriorating at an alarming pace, but scientists are optimistic space satellite imagery could help keep it from disappearing completely. The health of the Great Barrier Reef could soon be monitored from space if a joint project between American space agency NASA and Australia's CSIRO provides good results. There is sunglint northeast of the reef and there appears to be some sort of filamentous bloom in the Capricorn Channel.
