As a new proxy, biomarker stable hydrogen isotope is increasingly used to reconstruct hydrological cycles in the continents and ocean. In terrestrial environments, δD value of biomarkers can be used to reconstruct the δD value in rainfall, ancient altitude and evapotranspiration or lake water balance. In marine environments, changes of δD value of biomarkers can be interpreted more clearly in the context of relevant biological and environmental information. Many culture experiments and field data indicate that δD value of biomarkers can reflect δD value of surface water, and changes of seawater salinity. Many researchers also use δD value of marine biomarkers as a tool to reconstruct long term amounts of precipitation and surface seawater salinity. In this paper, the progress of biomarker stable hydrogen isotope of biomarkers and its application to marine paleoenviromental reconstruction are summarized.
