Reservoir masses here represents carbon stocks, measured in Pg C. Carbon exchange fluxes, measured in Pg C yr −1, occur between the atmosphere and its two major sinks, the land and the ocean. The black numbers and arrows indicate the reservoir mass and exchange fluxes estimated for the year 1750, just before the Industrial Revolution. The red ...
Most of the salt in the ocean comes from the weathering and erosion of rocks on land. [22] Some salts are released from volcanic activity or extracted from cool igneous rocks. [23] The oceans are also a reservoir of dissolved atmospheric gases, which are essential for the survival of many aquatic life forms. [24]
Viruses are the most abundant life in the ocean, harboring the greatest reservoir of genetic diversity. [256] As their infections are often fatal, they constitute a significant source of mortality and thus have widespread influence on biological oceanographic processes, evolution and biogeochemical cycling within the ocean.

An underwater environment is a environment of, and immersed in, liquid water in a natural or artificial feature (called a body of water), such as an ocean, sea, lake, pond, reservoir, river, canal, or aquifer. Some characteristics of the underwater environment are universal, but many depend on the local situation.
The ocean is the body of salt water that covers approximately 70.8% of Earth. [8] In English, the term ocean also refers to any of the large bodies of water into which the world ocean is conventionally divided. [9] The following names describe five different areas of the ocean: Pacific, Atlantic, Indian, Antarctic/Southern, and Arctic.
Data from a retired NASA mission has revealed evidence of an underground reservoir of water deep beneath the surface of Mars, according to new research. ... to fill oceans on the planet’s ...
The following tables offer estimates of oxygen cycle reservoir capacities and fluxes. These numbers are based primarily on estimates from (Walker, J. C. G.): [10] More recent research indicates that ocean life (marine primary production) is actually responsible for more than half the total oxygen production on Earth. [17] [18]
