As extensive as there has been maritime lifetime, there has been marine snow — a ceaseless drizzle of death and squander sinking from the surface area into the depths of the sea.

The snow starts as motes, which aggregate into dense, flocculent flakes that progressively sink and drift previous the mouths (and mouth-like apparatuses) of scavengers farther down. But even maritime snow that is devoured will most most likely be snowfall the moment far more a squid’s guts are just a rest prevent on this extended passage to the deep.

Though the phrase may advise wintry whites, maritime snow is primarily brownish or grayish, comprising typically dead factors. For eons, the debris has contained the same items — flecks from plant and animal carcasses, feces, mucus, dust, microbes, viruses — and transported the ocean’s carbon to be stored on the seafloor. Significantly, even so, marine snowfall is being […]
