Just four years after a major marine heat wave killed nearly half of Hawaii's coral reefs, researchers predict another round of hot water will cause some of the worst coral bleaching the region has ever experienced.
At the edge of an ancient lava flow where jagged black rocks meet the Pacific, small off-the-grid homes overlook the calm blue waters of Papa Bay on Hawaii's Big Island — no tourists or hotels in sight. Here, one of the islands' most abundant and vibrant coral reefs thrives just below the surface.
Researchers using high-tech equipment to monitor Hawaii's reefs are seeing early signs of bleaching in Papa Bay and elsewhere caused by a marine heat wave that has sent temperatures soaring to record highs for months. June, July and parts of August all experienced the hottest ocean temperatures ever recorded around the Hawaiian Islands. So far in September, oceanic temperatures are below only those seen in 2015.
In Hawaii, reefs are also a major part of the economy: Tourism thrives largely because of coral reefs that help create and protect iconic white sand beaches, offer snorkeling and diving spots, and help form waves that draw surfers from around the world. According to NOAA, the heat wave's causes include a persistent low-pressure weather pattern between Hawaii and Alaska that has weakened winds that otherwise might mix and cool surface waters across much of the North Pacific. What's causing that is unclear: It might reflect the atmosphere's usual chaotic motion, or it could be related to the warming of the oceans and other effects of human-made climate change.
Gove said researchers have a technological advantage for monitoring and gleaning insights into this year's bleaching, data that could help save reefs in the future.
