Carbon in the Oceans

11 January 2014

One new branch of Doomsaying CAGW is that the oceans are about to lose lots of carbon but here we have a paper that puts it into a different perspective. At … marine cyanobacteria, very tiny ocean plants, produce oxygen and make organic carbon using sunlight, and co2. They are engines of biogeochemical and nutrient cycles and nourish other organisms through the provision of oxygen and body mass and are thought to be the base of the ocean food chain. A paper in Science journal describes how cyanobacteria produce and release vesicles, spherules containing carbon and other nutrients that serve as food for other marine organisms. These vesicles contain DNA and it may be that they provide gene transfer withing and among bacteria communities.

The same story is at — vesicles are a previously unrecognised and unexplained component of dissolved organic carbon in marine ecosystems.
