Channels branch and rebranch through 300,000 hectares of mangrove forest, the waterways so tangled that the line between land and ocean dissolves entirely. This is the inner bay of the Berau Gulf, tucked into the hinge where New Guinea's Bird's Head Peninsula meets the Bomberai coast. Where most mangrove forests are thin coastal fringes, Bintuni's mangroves fill an entire bay -- 160 kilometers long, 70 kilometers wide at the mouth -- with trees that grow undisturbed to heights of 30 meters, among the tallest mangrove stands anywhere on the planet.

Researchers h...

Beneath its waters lie the gas reservoirs of the Tangguh field, one of the largest natural gas projects in the Asia-Pacific, operated by BP. The LNG processing plant sits on the bay's southern shore, its flare stacks visible for mile...

The rugged limestone ridges of the Bird's Head give way to alluvial lowlands, then to an unbroken expanse of deep green that spills into the sea. The mangrove canopy is so dense it obscures the water bene...
