Organic Matter in Recent and Ancient Sediments of Organic Rich Depositional Environments

这是一个地球化学研究的有机质转化， 秘鲁海流上升流体系下的沉积物。 的 主要研究者将通过以下方式评价新的脂质生物标志物： 确定他们记录的准确性， 厄尔尼诺（El Nino）导致生产力波动。 沉积物中有机质转化的研究 重要的是，他们将导致理解 石油的形成，以及了解 无机营养盐在沉积物-水中的再生 接口. 测试新的脂质生物标志物的准确性是 因为它们可以用来确定过去的记录 海洋生产力，这是当前地球科学的一个重要目标， 举措 私家侦探的样本是去年采集的;现在他会用高- 玻璃毛细管气相色谱分离柱 色谱法和电子轰击质谱法来分析 这些样品的烷烃，硬度，霍芬，芳烃，和 脂肪酸

This is a geochemical study of organic matter transformations in the sediments under the Peru Current upwelling system. The Principal Investigator will evaluate new lipid biomarkers by determining the accuracy with which they have recorded the history of El Ninyo (El Nino) derived productivity fluctuations. Such studies of organic matter transformations in sediments are important because they will lead to an understanding of petroleum formation as well as to an understanding of the regeneration of inorganic nutrient salts at the sediment-water interface. Testing the accuracy of the new lipid biomarkers is important because they could be used to determine the past record of oceanic productivity, an important goal of current geoscience initiatives. The PI's samples were taken last year; now he will use high- resolution glass-capillary gas chromatography, column chromatography, and electron impact mass spectrometry to analyse these samples for alkanes, stereness, hopenes, aromatics, and fatty acids.
