JGR: Biogeosciences focuses on biogeosciences of the Earth system in the past, present, and future and the extension of this research to planetary studies. The emerging field of biogeosciences spans the intellectual interface between biology and the geosciences and attempts to understand the functions of the Earth system across multiple spatial and temporal scales. Studies in biogeosciences may use multiple lines of evidence drawn from diverse fields to gain a holistic understanding of terrestrial, freshwater, and marine ecosystems and extreme environments. Specific topics within the scope of the section include process-based theoretical, experimental, and field studies of biogeochemistry, biogeophysics, atmosphere-, land-, and ocean-ecosystem interactions, biomineralization, life in extreme environments, astrobiology, microbial processes, geomicrobiology, and evolutionary geobiology.

JGR:生物地球科學關(guān)注地球系統(tǒng)過去、現(xiàn)在和未來的生物地球科學，并將這項研究擴展到行星研究。生物地球科學的新興領(lǐng)域跨越了生物學和地球科學之間的智力界面，并試圖了解地球系統(tǒng)在多個時空尺度上的功能。生物地球科學的研究可以使用來自不同領(lǐng)域的多種證據(jù)來全面了解陸地、淡水、海洋生態(tài)系統(tǒng)和極端環(huán)境。本節(jié)范圍內(nèi)的具體主題包括基于過程的生物地球化學、生物地球物理學、大氣、陸地和海洋生態(tài)系統(tǒng)相互作用、生物礦化、極端環(huán)境中的生命、天體生物學、微生物過程、地球微生物學和進化地球生物學的理論、實驗和現(xiàn)場研究。
