Marine biogeochemists are scientists who study the chemical, biological, and geological processes that govern the composition, structure, and dynamics of marine environments. They investigate how various chemical elements and compounds cycle through marine ecosystems, how they interact with marine organisms, and how they are affected by natural processes and human activities.

- What does a marine microbiologist do?
The study of biochemistry has been useful to marine biologists who observe similar biochemical processes occurring in widely divergent species. A marine biochemist might study biologically active compounds found in the ocean that might be useful in medicine, or the genetics of marine species.

A specific type of bacteria, Cyanobacteria, is known to be one of the oldest prokaryotes in existence and can perform both nitrogen fixation and oxygenic photosynthesis, the photosynthesis most associated with plants. Cyanobacteria can function using the pentose phosphate pathway and carbon dioxide as their only carbon source. Cyanobacteria are res...
The production of toxins is a defense mechanism used by many different organisms in many environments. Cyanobacteria are particularly well known for their toxin production abilities due to their sheer variety. There are known to be 34 species of cyanobacteria from 15 genera capable of producing toxins. These toxins include those that induce liver d...
The compound 2-hydroxyethyl-11-hydroxyhexadec-9-enoate was isolated from the cyanobacteriaLeptolyngbya species LY19. The compound was later shown to have antibiotic properties against Vibrio harveyi and Vibrio parahaemolyticus. These species of bacteria are predominantly fish and invertebrate pathogens and are known to be a particular burden on the...
The absorption of ultraviolet radiation (UVR) by organic matter in marine environments results in changes in the biochemistry of the surroundings, including the production of reactive oxygen species (ROS). These highly reactive chemicals have been shown to have a detrimental effect on microorganisms present in the environment by damaging their memb...
The changes in temperature observed across the world due to global warming not only affect the production of compounds such as ROS but also influence other aspects of marine life, such as coral reefs. They account for under 0.1% of the surface of the ocean but house approximately 25% of all marine species. The symbiotic relationship between the cor...
Although the destruction and bleaching of coral reefs is a pressing matter that has disastrous consequences, the more research performed and information gathered, the better-equipped conservationists are in combating it. The increased understanding we have of the biochemistry of marine biology and how changes affect it, the better we can prevent th...

They investigate the diversity, behavior, ecology, and interactions of bacteria, viruses, archaea, and protists in these ecosystems, using techniques such as DNA sequencing, microscopy, and biochemical assays.
