项目摘要
Bighorn Basin Coring Project (BBCP)W. Clyde, Lead PI, University of New HampshireAbstractThe Bighorn Basin Coring Project will collect ~200 meters of core from each of three sites (Polecat Bench, Gilmore Hill, Basin Substation) in the Bighorn Basin of Wyoming to better constrain the causes and effects of Paleogene hyperthermal events. Hyperthermals are abrupt, large-magnitude global warming events associated with extreme perturbations to the Earth's carbon cycle. Two events in particular will be targeted - the Paleocene-Eocene Thermal Maximum (PETM, ETM1) and the Elmo (ETM2) event. The PETM is the best documented hyperthermal and involved the release of 2,000-6,800 gigatons (Gt) of carbon from an unknown reservoir over less than 10 thousand years (ky) causing the earth to warm by 5-9ºC for a period of 100-200 ky. For comparison, the entire fossil fuel resource base on earth today is estimated to be ~5,000 Gt. Elmo is a smaller amplitude event that occurs after the PETM and just below the Chron C24N/C24R polarity reversal in marine records but remains poorly documented in continental sections. By applying a variety of sedimentological, geochemical, and palynological methods to the proposed cores we hope to better understand what caused these events, study the biogeochemical and ecological feedbacks that operated during them, and reveal precisely how they impacted continental environments. The Bighorn Basin preserves the most expanded stratigraphic records of the PETM and Elmo yet known, so these cores will provide an opportunity to study hyperthermals at unprecedented resolution.
大角盆地取心项目(BBCP)W。克莱德,首席PI,新罕布什尔大学摘要大角盆地取芯项目将从怀俄明州大角盆地的三个地点(Polecat Bench、Gilmore Hill、Basin Substation)中的每个地点收集约200米的岩心,以更好地限制古近纪超热事件的原因和影响。高温气流是一种突发的大规模全球变暖事件,与地球碳循环的极端扰动有关。两个事件将特别针对-古新世-始新世热最大值(PETM,ETM 1)和埃尔莫(ETM 2)事件。PETM是记录最好的超高温,涉及在不到1万年(ky)的时间内从未知的水库释放2,000 - 6,800千兆吨(Gt)的碳,导致地球在100-200 ky的时间内变暖5-9ºC。相比之下,今天地球上的整个化石燃料资源基础估计为~ 5,000 Gt。埃尔莫是一个较小幅度的事件,发生在古新世晚期之后,仅低于海洋记录中的Chron C24 N/C24 R极性反转,但在大陆部分的记录仍然很少。通过将各种沉积学、地球化学和孢粉学方法应用于拟议的岩心,我们希望更好地了解是什么导致了这些事件,研究在这些事件中起作用的地球化学和生态反馈,并准确地揭示它们如何影响大陆环境。大角盆地保存了迄今已知的最广泛的PETM和埃尔莫地层记录,因此这些岩心将提供一个以前所未有的分辨率研究超高温的机会。
