Tracking ocean temperatures in coral bleaching reversal research

Coral reefs are at a critical juncture. These underwater communities are bleaching and dying at an alarming rate as ocean temperatures rise. According to climate scientist Brian Von Herzen, corals are in danger of becoming "a geologic relic" in a remarkably short time. Only the coral reefs that are able to keep cool in the coming decades will survive this century, he says. Brian founded The Climate Foundation and is working on an emergency life support system for coral reefs. In this interview, he discusses the project and the role HOBO data loggers play in his research.
