Explore: Papua New Guinea


Vibrant Papua New Guinea

Our field expert-led expeditions to Papua New Guinea (PNG) converge on the numerous islands off the northern coast of the main island of New Guinea. A premier dive site, the Bismarck and Solomon Seas together comprise the eastern lobe of the Great Indo-Pacific Coral Triangle Region (CTR). Here you’ll discover stunning biodiversity, with more than half of all coral species found on earth, as well as vulnerable and endangered marine life, from Leatherback Turtles to Sei Whales.

The Bismarck Archipelago includes New Britain, New Ireland, New Hanover, and Bougainville, and is ideally suited to our Terra Explore Method of enveloping a region for scientific exploration. Participate in the scientific documentation and reporting of this unique environment, with the prospect of new discoveries, and exploration of amazing geologic forces and unmatched cultural diversity.
