Cocos Island, Costa Rica National Park, Explored By One World One Ocean (PHOTOS)

From One World One Ocean:

The second week of One World One Ocean's expedition to Cocos Island brought with it a new round of amazing underwater photos, which showcase the incredible biodiversity of this marine sanctuary.

Launched this year by MacGillivray Freeman Films, One World One Ocean (OWOO) is a nonprofit campaign, which, at its core, believes that good storytelling can change the word. Building on this platform, OWOO is travelling to all five ocean basins and using film, television, and new media to tell the most compelling ocean stories -- all designed to change the way people view the ocean and to spark a global movement to protect it.

The One World One Ocean crew is down in Costa Rica this week to capture a range of content to fuel upcoming media projects for its campaign, an important focus of which is the need for more marine protected areas like Cocos Island National Park. This ocean oasis enjoys official protection by the Costa Rican government, which means its many marine inhabitants, like the sharks and dolphins featured in these photos, are shielded from external threats -- like overfishing and oil drilling -- that threaten similar species in other areas.

Perhaps the biggest proponent of marine protected areas is world-renowned oceanographer and One World One Ocean partner scientist Dr. Sylvia Earle, whose wish as 2009 TED Prize winner was to "...use all means at your disposal -- films! expeditions! the web! more! -- to ignite public support for a global network of marine protected areas, hope spots large enough to save and restore the ocean, the blue heart of the planet."

In working with key partners like Earle and through the creation of cutting-edge content, One World One Ocean is positioned to be the largest, most far-reaching campaign of its kind in the ocean conservation space.
