Scientists hunt for heat-resistant coral in the US
Scientists in Florida are researching heat-resistant coral species to combat the effects of climate change on marine ecosystems. The program aims to restore reefs that have been devastated by record-breaking marine heatwaves.
Why it matters
Coral reefs are essential for coastal protection and marine biodiversity; their survival is directly threatened by rising ocean temperatures.
Offf the coast of Florida in the United States, a team of scientists and trained volunteers in scuba gear descends to the ocean floor and begins planting young coral onto a reef and examining how others are faring in the increasingly warm waters.
It is part of a long-running "Rescue a Reef" programme by the University of Miami that aims to advance conservation efforts and raise public awareness.
Part of that work involves researching which coral species are able to better withstand rapidly warming oceans as a result of human-caused climate change.
"Certain species may be more resilient, where they're able to better survive and recover from thermal stress events," said programme manager Devon Ledbetter during a recent dive to Rainbow Reef nearly 5km offshore from Key Biscayne.
Coral reefs support vibrant marine ecosystems, but also act as breakwaters, protecting coastlines from storm-driven erosion and flooding.
