Archaea are particularly numerous in the oceans, and the archaea in plankton may be one of the most abundant groups of organisms on the planet. Archaea are a major part of Earth's life and may play roles in both the carbon cycle and the nitrogen cycle.
Marine prokaryotes are marine bacteria and marine archaea. They are defined by their habitat as prokaryotes that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. All cellular life forms can be divided into prokaryotes and eukaryotes.

Marine protists are defined by their habitat as protists that live in marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. Life originated as marine single-celled prokaryotes (bacteria and archaea) and later evolved into more complex eukaryotes.
May 16, 2017 · Extremophiles belonging to the Eubacteria, Archaea, and Eukarya kingdoms produce extremophilic biomass in ecological niches such as oceans, salt marshes, solar salterns, hypersaline lakes, hot springs, marine hydrothermal vents, and soda lakes. These marine polye-xtremophiles have great importance and contributed a lot in biotechnological ...

Mesophilic archaea discovered in the marine water column. Prior to 1992, archaea were thought to exist as one of three types—either an extremist that lives in very salty environments (a halophile), an extremist that lives in scalding hot water (a thermophile), or as a methane producer (a methanogen).

Marine Microbiology | Microbiology Society. Covering over 70% of the Earth’s surface, the Oceans represent an incredibly diverse, yet understudied ecosystem. In particular, microorganisms (bacteria, fungi, viruses and archaea) mediate key ecosystem processes in these marine systems and account for a majority of the biodiversity.
