Part of the marine carbon cycle transforms carbon between non-living and living matter. Three main processes (or pumps) that make up the marine carbon cycle bring atmospheric carbon dioxide (CO 2) into the ocean interior and distribute it through the oceans. These three pumps are: (1) the solubility pump, (2) the carbonate pump, and (3) the ...
Today, marine species range in size from the microscopic phytoplankton, which can be as small as 0.02–micrometres; to huge cetaceans like the blue whale, which can reach 33 m (108 ft) in length. [5] [6] Marine microorganisms have been variously estimated as constituting about 70% [7] or about 90% [8] [1] of the total marine biomass.
In marine environments, microbial primary production contributes substantially to CO 2 sequestration. Marine microorganisms also recycle nutrients for use in the marine food web and in the process release CO 2 to the atmosphere. Microbial biomass and other organic matter (remnants of plants and animals) are converted to fossil fuels over ...
General characteristics of a large marine ecosystem (Gulf of Alaska). Marine life, sea life or ocean life is the collective ecological communities that encompass all aquatic animals, plants, algae, fungi, protists, single-celled microorganisms and associated viruses living in the saline water of marine habitats, either the sea water of marginal seas and oceans, or the brackish water of coastal ...
[10] [11] [12] Rather than host-associated microbes functioning independently, complex multi-assemblage microbiomes have major impact on the fitness and function of their hosts. Studying these complex interactions and biological outcomes is difficult, but to understand the origin and evolution of organisms and populations and the structure and ...
Biological oceanography is the study of how organisms affect and are affected by the physics, chemistry, and geology of the oceanographic system.Biological oceanography may also be referred to as ocean ecology, in which the root word of ecology is Oikos (oικoσ), meaning ‘house’ or ‘habitat’ in Greek.
The pelagic food web, showing the central involvement of marine microorganisms in how the ocean imports nutrients from and then exports them back to the atmosphere and ocean floor. A marine food web is a food web of marine life. At the base of the ocean food web are single-celled algae and other plant-like organisms known as phytoplankton.
Marine Biology is a peer-reviewed scientific journal covering research on all aspects of marine biology. The journal was established in 1967 and is published monthly by Springer Science+Business Media. The editor-in-chief is Ulrich Sommer (Helmholtz Centre for Ocean Research).
