We have been conducting reef assessments in the Gambier group of islands which are a collection of extinct high volcanic islands more than 1,600 km southeast of Tahiti. For twelve days of this mission, the scientists characterized the complex reef systems of Mangareva, an archipelago located in the southern hemisphere where the climate is tropical, but tempered by southeast trade winds.

Announcing the 15th Annual Science Without Borders® Challenge: Navigate with Care
Every day, fishing boats, ferries, sailboats, kayaks, research vessels, cargo ships, whales, sea turtles, dolphins, seabirds, and countless other marine animals share the same waters. While people rely on the ocean for transportation, recreation, research, fishing, and exploration, it is also home to some of the most diverse and important ecosystems on Earth.
That simple but powerful idea is the inspiration behind the 15th Annual Science Without Borders® Challenge.
