This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). This study will quantitatively reconstruct deep ocean carbonate chemistry changes across the Paleocene-Eocene thermal maximum to determine the degree of ocean acidification during a past period of high CO2 and extreme warming. The PIs will generate records from multiple sites in different water depths and different oceans using palaeontological, geochemical, and modeling techniques. There will be particular focus on the application of two Boron-based proxies for ocean pH. Ocean acidification is a topic of great societal concern because of its impact on marine organisms and on the rate at which the ocean can absorb additional CO2 from the atmosphere. The research will involve graduate and undergraduate students at the four participating institutions.

该奖项是根据2009年《美国复苏和再投资法案》(公法111-5)提供资金的。这项研究将定量重建跨越古新世-始新世最热时期的深海碳酸盐化学变化，以确定过去高二氧化碳和极端变暖时期的海洋酸化程度。PI将使用古生物、地球化学和建模技术，从不同水深和不同海洋的多个地点生成记录。将特别侧重于两种以硼为基础的海洋pH代用品的应用。海洋酸化是一个非常受社会关注的话题，因为它对海洋生物和海洋从大气中吸收额外二氧化碳的速度有影响。这项研究将涉及四个参与机构的研究生和本科生。
