At those depths, the water is filled with slowly drifting particles known as "marine snow," part of a never-ending deluge of debris from the world above. The tiny globs of "snow" are made up of ...

The research revealed an average of 29 microplastic particles per liter of melted snow. Of the 13 types of plastics, the most common was polyethylene terephthalate (PET), which is used to ...

In the laboratory, the particles can be viewed for longer periods, but the trek ashore degrades the delicate marine snow and kills the living organisms within it. Tiny particles (white dots ...

"These are very fine particles, not big flakes," study co-author Kerri Cahoy, of the Massachusetts Institute of Technology in Cambridge, said in a statement. An astronaut standing among snow ...

clouds of snow blanket the Red Planet's poles - but unlike our water-based snow, the particles on Mars are frozen crystals of carbon dioxide. Most of the Martian atmosphere is composed of carbon ...

Already in the 1980s it was suggested that aggregates, so-called "marine snow particles," could possibly be suitable sites for N 2 fixation, and this was recently confirmed. Still, it has been an ...

"One line of evidence for snow is that the carbon-dioxide ice particles in the clouds are large enough to fall to the ground during the lifespan of the clouds," said co-author David Kass ...
