Ocean temperature rise caused coral bleaching at depths over 90m
In November 2019, researchers from University of Plymouth recorded unexpected evidence of coral bleaching more than 90 metres below the ocean surface.
Describing their discovery as a "huge surprise," Dr Phil Hosegood, Associate Professor in Physical Oceanography at the University of Plymouth and lead on the project, said: "Deeper corals had always been thought of as being resilient to ocean warming, because the waters they inhabit are cooler than at the surface and were believed to remain relatively stable."
