NewsHitchhiking bacteria can alter marine snow's role as a carbon sink
Researchers have found that when bacteria hitch a ride on marine snow particles, the microbes can eat away at calcium carbonate, which is an essential ballast that helps particles sink.

NewsDeep-sea microbes get unexpected energy boost
A study shows that sinking organic particles—known as marine snow—begin to leak dissolved carbon and nitrogen when they reach depths of 2–6 kilometres, presenting microbes in the surrounding seawater with nutrients. The leakage is caused by the intense hydrostatic pressure in the deep ocean.

NewsNitrogen fixation on marine snow particles is widespread in the world's oceans
Researchers have shown that bacteria attached to marine snow particles can fix N2 over a wide range of temperatures in the global oceans, from the tropics to the poles, and from the surface to the abyss, accounting for about 10% of the overall N2 fixation in oceans.

NewsTiny poops in the ocean may help solve the carbon problem
Zooplankton could capture carbon dioxide originating from Earth’s atmosphere and deposit it deep into the sea as feces. The new technique mooted consists of spraying clay dust on the surface of the ocean at the site of large blooms of phytoplankton.

NewsHidden trails of marine snow can affect how the ocean stores carbon
A new study reveals never-before seen mucus ‘parachutes’ produced by microscopic marine organisms that significantly slow their sinking, putting the brakes on a process crucial for removing carbon dioxide from the atmosphere.
