Marine chemistry, also known as ocean chemistry or chemical oceanography, is the study of the chemical composition and processes of the world’s oceans, including the interactions between seawater, the atmosphere, the seafloor, and marine organisms [2]. This field encompasses a wide range of topics, such as the cycling of elements like carbon ...
Biological oceanography. 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 principal marine primary producers are cyanobacteria, algae and marine plants. The oxygen released as a by-product of photosynthesis is needed by nearly all living things to carry out cellular respiration. In addition, primary producers are influential in the global carbon and water cycles.
t. e. Marine biogeochemical cycles are biogeochemical cycles that occur within marine environments, that is, in the saltwater of seas or oceans or the brackish water of coastal estuaries. These biogeochemical cycles are the pathways chemical substances and elements move through within the marine environment. In addition, substances and elements ...
Biological productivity (photosynthesis) in marine ecosystems is often limited by the bioavailability of nitrogen. [6]The amount of bioavailable nitrogen (nitrate (NO 3 −), nitrite (NO 2 −), and ammonium (NH 4 +)) depends on the inputs from nitrogen fixation and losses from denitrification and anammox as dinitrogen gas (N 2), a compound only accessible to nitrogen-fixing bacteria.
John F. Marra is a biological oceanographer, academic, and author. He has been a member of the CUNY Doctoral Faculty in Earth and Environmental Sciences as well as the Doctoral Faculty in Biology since 2007. [1] Marra's research encompasses oceanography, phytoplankton, ocean optics, and photosynthesis. He participated in 28 oceanographic ...
October 24, 2024 at 1:58 AM. Central Jersey native Joe Gradone grew up less than 40 miles from the Atlantic Ocean, but his fascination with oceanography first surged while studying geology as an ...
Oceanography. Oceanography (from Ancient Greek ὠκεανός (ōkeanós) ' ocean ' and γραφή (graphḗ) ' writing '), also known as oceanology, sea science, ocean science, and marine science, is the scientific study of the ocean, including its physics, chemistry, biology, and geology. It is an Earth science, which covers a wide range of ...
