Researchers Investigate Oxygen Production Discovered in Deep-Sea Metal Nodules

A newly identified process occurring in the darkest depths of the ocean has prompted researchers to launch a mission to better understand its implications. Reports reveal that metal nodules on the seafloor could generate oxygen in the absence of solar light. This unexpected discovery could have important implications for understanding life in extreme environments, both on Earth and potentially on other planets. The research is expected to discover how oxygen could support life in conditions previously considered inhospitable.

Findings from seabed studies

According recommendations Published in Nature Geoscience, sensors placed on the seafloor at depths of approximately 5 km between Hawaii and Mexico recorded increasing oxygen levels. The discovery challenges the long-held belief that oxygen production occurs solely through photosynthesis. The lead researcher, Professor Andrew Sweetman of the Scottish Marine Science Association, explained told BBC Information that the metal nodules were found to generate electrical currents capable of splitting seawater into oxygen and hydrogen.

Potential impact on extraterrestrial life research

Reports indicate that this advancement has attracted the attention of NASA experts. Professor Sweetman said during a press conference that the collaborations with NASA aim to explore how the process could enable microbial life on other planets or moons. He emphasized that understanding this phenomenon could reshape the scientific approach to identifying life beyond Earth.

Debates around deep sea mining

The findings have intensified debates about the environmental risks of deep-sea metal nodule mining. Critics, including environmental organizations and marine scientists, argue that the discovery underscores the need to reassess seabed mining activities. A petition signed by more than 900 scientists calls for a pause in mining operations to prevent possible damage to marine ecosystems.

Professor Sweetman, referring to concerns raised by mining companies such as Canada’s Metals Firm, said upcoming experiments would provide conclusive evidence. He advocated a cautious approach and stressed the importance of understanding deep-sea ecosystems before proceeding with large-scale industrial activities.
