The existence of a planetary homeostasis influenced by living forms had been observed previously in the field of biogeochemistry, and it is being investigated also in other fields like Earth system science.

Classes are offered in Summer and Fall and course topics range from Microbial Oceanography : The Biogeochemistry, Ecology and Genomics of Oceanic Microbial Ecosystems, to Marine Invertebrate Zoology and Coral Reef Ecology.

A landmark paper in 1980 by Marilyn Epstep, now M . Fogel, and Thomas Hoering titled " Biogeochemistry of the stable hydrogen isotopes " refined the links between organic materials and sources.
44.
Though bacteria that metabolize hydrocarbons are fascinating ( and currently highly studied ), there is no " textbook " support for the notion that they make meaningful contributions to the biogeochemistry of terrestrial ecosystems.
45.
The USC Wrigley Institute has specialized programs in environmental microbiology, geobiology, ocean biogeochemistry, living marine resources ( including fisheries and aquaculture ), climate change, coastal environmental quality and the urban ocean.
46.
In the original version of IBIS [ Foley et al . 1996 ] there was no explicit belowground biogeochemistry model to complete flow of carbon between the vegetation, detritus, and soil organic matter pools.

Some of the major fields of study within aquatic sciences include : limnology ( study of lakes, rivers, wetlands and groundwater ); biogeochemistry; aquatic ecology; oceanography; marine biology; and hydrology.

Ten tonnes of ferrous sulphate dissolved in seawater was spread over an area of 300 square kilometers, and the patch created was monitored for 38 days to investigate the effects of iron addition on marine biogeochemistry and ecosystem.
49.
"Our results show that water and sediment storage in reservoirs behind the ` Iron Gates'have altered the biogeochemistry not just of the river and adjacent coastal waters, but of the entire Black Sea basin,"

Through a creative combination of experiments simulating high CO?ancient polar environments, and modelling of forest biogeochemistry, his group s analyses helped define our modern understanding of the physiological ecology of Mesozoic high-latitude forests [ ref ].
