11. Since then she has done extensive work on climate modeling, biogeochemical cycles , and climate change. 12. These microbes play a vital role in biogeochemical cycles . 13. He was the founding editor for the American Geophysical Union's journal " Global Biogeochemical Cycles ". 14. During this time he researched the biogeochemical cycle of sulfur in the ocean and in the atmosphere. 15. Hydrogen sulfide is a central participant in the sulfur cycle, the biogeochemical cycle of sulfur on Earth. 16. Throughout history, the Earth's atmosphere and biogeochemical cycles have been in a dynamic equilibrium with planetary ecosystems. 17. The role members of the Roseobacter lineage play in marine biogeochemical cycles and climate change cannot be overestimated. 18. The "'mercury cycle "'is a biogeochemical cycle involving evaporates, though it takes quite a while to do so. 19. Microbial life plays a primary role in regulating methane metabolism, and sulfur metabolism ) control global biogeochemical cycling . 20. Some may use the terms biogeochemical cycle and geochemical cycle interchangeably because both cycles deal with Earth�s reservoirs.
