Microscopic meiofauna moves across a glass slide under a microscope. This extremophile organism, known for surviving extreme environments, is part of the biological sampling effort during the deep-sea expedition at the Nankai Trough dive site.

The Hidden Majority: James Fleming on the wonderful world of meiofauna

At a glance, marine sediment might seem lifeless, just mud beneath the waves. But for James Fleming, postdoctoral researcher at JAMSTEC, that mud holds entire worlds.

JAMSTEC Shinkai Expedition – Dive Site: Shichiyo Seamounts

Rising from the deep seafloor south of mainland Japan, the Shichiyo Seamounts, a dive site of the JAMSTEC Shinkai expedition, are part of a chain of underwater volcanoes formed by tectonic activity along the Izu–Ogasawara Arc.

Crew members in brightly colored safety gear guide a deep-sea submersible being lowered into the ocean from a research vessel during a scientific operation. The submersible is suspended mid-air by a large deployment crane as it prepares to descend to a designated dive site in the Nankai Trough, a geologically active trench off Japan’s coast. The operation is part of a deep-sea expedition focused on exploring and documenting marine biodiversity in extreme ocean environments.

JAMSTEC Shinkai Expedition – Dive Site: Nankai Trough

The Nankai Trough, stretching along the southeastern coast of Japan, is one of the most geologically active and biologically important deep-sea regions in the western Pacific.
