When the Sea Began to Steam: Science at the Bismarck Sea Eruption

Olgeta Foundation Supports Scientific Exploration in Papua New Guinea's Remote Waters

On 8 May 2026, something extraordinary began unfolding beneath the waters of the Bismarck Sea. Approximately 125 kilometres southeast of Manus Island, an underwater volcanic eruption sent towering plumes of steam and gas above the ocean, while vast areas of seawater turned unusual shades of green and turquoise.

Satellite images captured the remarkable event, revealing floating volcanic rock and dramatic changes across the ocean's surface. Yet beneath the water, scientists faced an important mystery: the precise volcanic features responsible for the eruption remained poorly understood.

For researchers, this was a rare opportunity to investigate one of Papua New Guinea's most dynamic and least explored underwater environments.

Supporting Scientific Exploration

As part of its commitment to marine research and conservation, Olgeta Foundation made MV Golden Dawn available as a support vessel for a scientific survey associated with the eruption.

Operating in remote waters presents significant logistical challenges. Reliable vessels are essential for transporting scientific teams, carrying equipment and supporting offshore research activities.

Through MV Golden Dawn, Olgeta Foundation helps make scientific exploration possible in areas where access would otherwise be difficult.
