Clay minerals are a major constituent of the earth's surface and are mainly found in the sediments of lakes, rivers and oceans. The properties of clay and claystone crucially depend on how the tiny ...

Invisible clouds of sediment created by underwater mining spread for miles, putting ocean floor ecosystems at risk.

The concentrations of microplastics in the surface layer of the oceans are lower than expected. Researchers experimentally demonstrated that microplastics interact with natural particles and form ...

On the abyssal plains, at depths between 3,000 and 6,000 meters, polymetallic nodules are scattered across millions of square kilometers, much like potatoes in a field. These mineral ores are formed ...

New research led by scientists at Germany’s Helmholtz Centre for Ocean Research Kiel outlines the possible effects of deep-sea mining on midwater marine species. In a paper published in the journal ...

Soil gathered from various terrains consists of several characteristics, offering fingerprints to their origin. As per the International Union of Soil Science (IUSS) standard, the soil category could ...

Researchers modeled the journey of microplastics released in wastewater treatment plant effluent into rivers of different sizes and flow speeds, focusing on the smallest microplastic fragments — less ...
