Under this award the PIs will develop lipid biomarker proxies that will assist the study of marine cyanobacteria in both the modern ocean and in the geological record. The PIs will test the hypothesis that cyanobacteria are a dominant source of distinctive lipids known as bacteriohopanepolyols (BHP.s) produced in the marine water column and likely to be recorded in underlying sediments. If proven, it will provide a sound basis for attributing a specific biological origin to some of the hopane hydrocarbons that occur abundantly in ancient sediments and petroleum.

根据该奖项，PI 将开发脂质生物标志物代理，以协助研究现代海洋和地质记录中的海洋蓝藻。 PI 将检验以下假设：蓝藻是海水柱中产生的细菌藿烷多元醇 (BHP.s) 等独特脂质的主要来源，并且可能记录在底层沉积物中。 如果得到证实，它将为古代沉积物和石油中大量存在的一些藿烷烃的特定生物起源提供坚实的基础。
