Did you know that it snows under the sea? ‘Marine Snow’ is a constant shower of organic materials that fall from the upper ocean to the deep sea.
Just like leaves falling from a tree to the forest floor, dead plant and animal life (along with fecal matter, sand, soot, and other inorganic dust) slowly sink in our world’s oceans.
The difference is that in the ocean, it can take weeks before a particle reaches the ocean floor!
Animals in the deep sea rely on this marine snow as a vital source of food, mainly because the particles are rich with Nitrogen and Carbon. Scientists have even found that the larvae of deep sea animals couldn’t survive without such a food source!
What doesn’t get consumed by marine life compiles on the seafloor, where the snow is decomposed further. The end result is a thick ooze that covers three-quarters of the ocean’s floor! This ooze of decomposed organic materials grows 6 meters every million years.
