carbon cycle

Scientists in Canada trace how aquatic communities change as Quebec’s Romaine River flows into the sea.

The first evidence of biologically produced elemental carbon inspires more questions than answers.  

A modeling study estimates that by drastically reducing fish biomass over the past century, industrial fishing may be affecting ocean chemistry, nutrient fluxes, and carbon cycling as much as climate change.

Microbiologists identify diatoms, algae, and cyanobacteria species from samples above a mountaintop in France.

Newly discovered and rather phallic-looking clams dwell at the bottom of the ocean and are some of only a few animals known to eat wood.  

Scientists estimate that subterranean organisms constitute a massive amount of carbon, 245 to 385 times greater than that contained in all humans.

With samples taken from the crust of the Mid-Atlantic Ridge, researchers have discovered where some of the oceans’ dissolved organic carbon winds up.

Viruses are responsible for the majority of archaea deaths on the deep ocean floors, scientists show.

Bathyarchaeota undergo acetogenesis, generating organic carbon below the seafloor.

Viruses abound in the world’s oceans, yet researchers are only beginning to understand how they affect life and chemistry from the water’s surface to the sea floor.

Ocean viruses can impact marine ecosystems in several ways.

Researchers find remarkably active bacteria in the Mariana Trench, where they live under pressure 1,000 times greater than at the surface.
