Marine dissolved organic matter (DOM) contains more carbon than the combined stocks of
Earth's biota. Organisms in the ocean continuously release a myriad of molecules that …

Microbial cells (ie, bacteria, archaea, microeukaryotes) in oceans secrete a diverse array of
large molecules, collectively called extracellular polymeric substances (EPSs) or simply …

The biological pump is a process whereby CO2 in the upper ocean is fixed by primary
producers and transported to the deep ocean as sinking biogenic particles or as dissolved …

SAR11 is a group of small, carbon-oxidizing bacteria that reach a global estimated
population size of 2.4× 1028 cells—approximately 25% of all plankton. They are found …

The ocean has been a regulator of climate change throughout the history of Earth. One key
mechanism is the mediation of the carbon reservoir by refractory dissolved organic carbon …

Marine dissolved organic carbon (DOC) exhibits a spectrum of reactivity, from very fast
turnover of the most bioavailable forms in the surface ocean to long-lived materials …

Dissolved organic matter (DOM) in the oceans is one of the largest pools of reduced carbon
on Earth, comparable in size to the atmospheric CO2 reservoir. A vast number of …

Photosynthesis in the surface ocean produces approximately 100 gigatonnes of organic
carbon per year, of which 5 to 15 per cent is exported to the deep ocean,. The rate at which …

A fraction of the carbon captured by phytoplankton in the sunlit surface ocean sinks to depth
as dead organic matter and faecal material. The microbial breakdown of this material in the …

Dissolved organic carbon (DOC) release by seaweeds (marine macroalgae) is a critical
component of the coastal ocean biogeochemical carbon cycle but is an aspect of seaweed …
