Researchers have uncovered a groundbreaking hydrothermal field off the coast of Papua New Guinea, characterized by an unusual duality. Located 1,300 meters deep, this site features hot hydrothermal fluids rising from beneath the seafloor alongside significant methane and other hydrocarbon emissions from sediments.
The discovery was made by Dr. Philipp Brandl and his team on the SONNE expedition SO299 DYNAMET. They used advanced surveying technology to illuminate the unique features of the field, which has not been documented elsewhere.
Conical Seamount’s geological makeup creates a hybrid environment where warm waters and cold gases escape mere centimeters apart, supporting a diverse deep-sea ecosystem. This habitat is home to numerous organisms, including Bathymodiolus mussels, tube worms, shrimp, and vividly colored sea cucumbers.
The site’s unique gas composition impacts both its ecological and geological characteristics, leading to the accumulation of precious metals in surrounding rocks. However, this remarkable ecosystem faces serious threats from human activity, including mining operations and exploration licenses.
Researchers emphasize the urgency of investigating this region further, advocating for marine spatial planning and protective measures to safeguard the valuable ecosystem and its inhabitants. The discovery highlights the dual challenge of exploiting natural resources while preserving unique marine environments.
