Metal-rich particle clouds in the Black Sea mapped

METU Institute of Marine Sciences researchers have detailed and mapped metal-rich nanoparticle clouds extending 150 kilometers offshore in the depths of the Black Sea.

Scientific Expedition and Mapping Studies

Experts from the Middle East Technical University Institute of Marine Sciences conducted a comprehensive one-week scientific summer expedition in the Black Sea during the last week of August. During this expedition, the physical, chemical, and biological properties of seawater were examined in detail, while invisible metal-rich particle clouds were also mapped.

New Sensors and Research Process

Institute Deputy Director Prof. Dr. Mustafa Yücel stated that they have been tracking this formation for 7 to 8 years and have been investigating the issue in more detail over the past 3 years thanks to new technologies developed with the support of the European Research Council. It was stated that the ongoing studies were carried out along a line extending from the mouth of the Sakarya River in the western Black Sea to approximately 150 kilometers offshore.

Anoxic Environment and Metal Density

It was reported that the Black Sea possesses the world's largest anoxic marine volume below a depth of approximately 100 meters. While special microbial formations occur at the boundary between this oxygenated and anoxic environment, it was determined that iron and manganese concentrations are high in the nanoparticle clouds formed by the accumulation of particles transported by rivers and the atmosphere.

Potential Contribution to Technology and Space Research

It was noted that the findings could open new synthesis pathways for fields such as nanotechnology, materials science, energy, batteries, and microchips, alongside marine sciences. Additionally, it was reported that because the anoxic and dark environment of the Black Sea shares similarities with oceans discovered in the Solar System, it could provide significant contributions to space research.
