Sentinel satellite probes coral health from orbit
24 May 2016
Scientists are working on techniques that would allow them to routinely monitor the health of corals worldwide from orbit.
The EU's new Sentinel-2a satellite has the capability to look into the water column, to see whether reefs are undergoing change.
Current, anomalously high temperatures are driving a huge coral bleaching event across the globe.
Early work suggests the Sentinel can detect the effects from 780km up.
