Estimating carbon sequestration from plankton poop
Copepod fecal pellets—plankton poop—transport carbon from the ocean surface to the deep where it is stored for thousands of years.…

Ocean eddies suck carbon out of the atmosphere, thanks to plankton
When phytoplankton sink into the deep ocean, they take carbon with them, storing CO2 away from the atmosphere. This new…

Microbes foil attempts to increase deep ocean carbon sequestration
Most carbon emitted to the atmosphere ends up in the ocean, much of it in organic molecules. While most is…
