£3.7 Million Imperial College Project to Unlock Secrets of Maldivian Deep Coral Reefs

Imperial College London has launched a £3.7 million research initiative to conduct the first comprehensive assessment of deep coral reef ecosystems in the Maldives, targeting reef systems at depths of 30 to 150 metres that have remained largely unstudied. The five-year project, funded by the UK Natural Environment Research Council, will deploy advanced remotely operated vehicles and environmental DNA sampling techniques to map biodiversity in these poorly understood habitats.

The collaboration brings together researchers from Imperial College and the University of Plymouth, working in partnership with the Maldives Environmental Protection Agency and the Maldives Marine Research Institute. The team will establish 24 permanent monitoring stations across six atolls, creating a baseline dataset against which future changes in deep reef health can be measured.

Deep coral reefs, often referred to as mesophotic ecosystems, are of particular interest because they may serve as refugia for species displaced from shallow reefs by rising sea temperatures. If deeper reefs harbour viable populations of key coral species, they could potentially reseed damaged shallow reefs during recovery periods. However, scientists caution that this 'deep reef refugia hypothesis' remains unproven in the Indian Ocean context.

Dr. Sarah Collins, the project's principal investigator at Imperial College, said the research has direct implications for Maldivian conservation policy. 'We cannot protect what we do not understand,' she told journalists at the project launch in Malé. 'These deeper reefs may hold the key to long-term reef resilience, but they face their own threats from bottom-trawling, anchor damage, and the downward migration of warming waters.'
