On the Line

An underwater paradise in the remote Pacific Ocean that includes the sea around the southern Line Islands (Caroline Island is seen here) will be protected—thanks in part to National Geographic’s Pristine Seas project. Led by Explorer-in-Residence Enric Sala, the project is an ongoing effort to document and conserve what’s left of the planet’s least spoiled marine environments.
