Funds support the acquisition of a new gas chromatograph to be used in paleoceanography and paleoclimate research at Brown University, specifically in the application of alkenone paleothermometry to understanding the ocean's role in climate change on timescales that range from tens to millions of years and from regional to global scales. Existing equipment in the laboratory has played a central role in high profile research and in training a large number of young scientists, but it has reached the end of its serviceable life and must be replaced. The more modern capabilities of the new instrument will also enable to laboratory to expand its toolbox to include a wider array of biomarker-based proxies for paleoenvironmental reconstructions.The broader impacts include technical training for graduate and undergraduate students, both at Brown and from collaborating institutions, which further supports student research opportunities. The lead investigator also maintains an active outreach program for high school students and teachers each summer in which biomarker analysis is a major component. Results of biomarker research are also disseminated more generally through publications and an active speaking program to general audiences.

资金支持获得布朗大学的古平均摄影和古气候研究中使用的新气相色谱仪，特别是在应用烷酮的古热温度计中，以了解海洋在从数十万年到数百万年度到数百万年度到全球量表的气候变化中海洋在气候变化中的作用。实验室中的现有设备在知名研究和培训大量年轻科学家方面发挥了核心作用，但是它已经达到了可维修生活的终结，必须更换。新仪器的更现代能力还将使实验室扩展其工具箱，以包括一系列基于生物标志物的基于生物标志物的古环境重建代理。更广泛的影响包括在Brown和Brown的研究生和本科生的技术培训，包括在Brown和合作学院进行协作，以进一步支持学生研究机会。每年夏天，首席研究人员还为高中生和老师维护了一项积极的外展计划，其中生物标志物分析是主要组成部分。生物标志物研究的结果还通过出版物和向普通观众进行积极的口语计划进行了更普遍的传播。
