Internal-wave cooling – hope for coral reefs

Global heating threats to coral reefs have received significant attention in the literature and media. In a new study across the Pacific Ocean, we show widespread cooling of reefs by internal waves – a ubiquitous process reducing heating accumulation in potential refuge habitats.
