with coral bleaching. a bleaching event is when the coral dies en masse due to unusually warm sea temperatures. one of the biggest ones was the first one in 1998, which affected about — more than 90% of our coral. and we did get a lot of recovery but then, these events are getting more and more frequent. so, we had one in 2010 and then, we had another one 2015—16 and now, we're bracing ourselves for another event. but amid this bleaching onslaught, the team has made an important and unexpected discovery — some of the corals in fulhadhoo have managed to survive. they show high thermal resilience because they've been surviving in — in these conditions and in really shallow waters that leave them exposed at low tide. so, they're now planting more of these resilient corals.
