The Oceanic carbon cycle is a central process to the global carbon cycle and contains both inorganic carbon (carbon not associated with a living thing, such as carbon dioxide) and organic carbon (carbon that is, or has been, incorporated into a living thing). Part of the marine carbon cycle transforms carbon between non-living and living matter.

That was a great step toward protection of riverine habitats and improvement of water quality. [22] Because of the U.S Constitution, the federal government can only protect interstate waters that is used for navigation, which is defined as the "waters of the United States" (WOTUS).
