The Slow Life Movement: A Microbial Perspective of the Subsurface Biosphere

On the seafloor, “marine snow” is constantly falling. Bits of dead plankton, decaying fecal material, biological remnants from shore – it all finds its way to the bottom of the ocean, delivering needed sources of organic molecules and energy to the microbial communities lying in wait. Over time, this snow – along with sediment mineral grains – accumulates, burying previous layers. In Denmark’s Aarhus Bay, for example, digging ten meters down beneath the seafloor is like going 8,700 years
