项目摘要
AbstractHerbert 0545525This project is preliminary work towards the development of deuterium/hydrogen isotopic ratios as a proxy for isotopic composition of surface water. Alkenones produced by algae will be used as a source for the D/H ratios, both from laboratory cultures and available tropical cores. Laboratory cultures will determine whether and to what degree other environmental factors such as salinity, temperature, and nutrient availability affect D/H. The laboratory results will be verified using natural samples from the tropical cores. The current analytical technique will also be developed and improved. It is hoped that this work will be successful enough to lead to a full proposal to further develop the use of D/H as a paleoceanographic proxy.
本项目是发展氘/氢同位素比值作为地表水同位素组成的代表的初步工作。藻类产生的烯酮将被用作D/H比的来源,无论是从实验室培养和可用的热带核心。实验室培养将确定其他环境因素(如盐度、温度和养分可利用性)是否以及在多大程度上影响D/H。实验室结果将使用热带岩心的天然样本进行验证。目前的分析技术也将得到发展和改进。希望这项工作能够取得足够的成功,从而提出一项全面的建议,进一步发展D/H作为古海洋学代用指标的用途。
