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.
