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.

资金用于支持布朗大学购置一台新的气相色谱仪，用于古海洋学和古气候研究，特别是应用烯酮古温度测量法，以了解海洋在从几千万年到几百万年以及从区域到全球范围的时间尺度上对气候变化的作用。实验室的现有设备在引人注目的研究和培训大批青年科学家方面发挥了核心作用，但其使用寿命已到，必须更换。新仪器的更现代化的功能也将使实验室能够扩展其工具箱，包括更广泛的基于生物标志物的古环境重建代理。更广泛的影响包括对布朗大学和合作机构的研究生和本科生进行技术培训，进一步支持学生的研究机会。首席研究员每年夏天还为高中学生和教师开展积极的外展计划，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也通过出版物和积极的演讲计划更广泛地传播给普通观众。
