中文摘要
Pis将对海底甲烷水合物中微量气体的浓度进行研究,并用最先进的地球化学仪器测定它们的年代。对水合物定年对于了解水合物形成和解离的机制和速率至关重要,因为甲烷水合物是海洋碳的主要暂存库。计划进行Pb-210/Pb-206、C-14、CfC11/12、Kr-85和Th-230分析。
英文摘要
Kastner OCE-9817612 The Pis will conduct research on the concentration of trace gases in seafloor methane hydrates and on dating them with state-of-the-art geochemical instrumentation. Dating hydrates is essential for under- standing the mechanisms and rates of hydrate formation and dissociation and because methane hydrates constitute a major transient sink of oceanic carbon. Pb-210/Pb-206, C-14, CfC11/12, Kr-85 and Th-230 analyses are planned.
