项目摘要
The warm mid-Pliocene, when on average global temperature was 2-3 degrees C warmer than at present, is within the range of the Intergovernmental Panel on Climate Change (IPCC) projections of global warming for the 21st century, and hence offers a good analog for future climate change. This work, conducted by a team of scientists from Rutgers University, will generate new geochemical proxy records (Mg/Ca, B/Ca, and Neodymium isotope composition) from deep sea sediment cores that will provide key constraints on spatial and temporal variations in the deep ocean hydrography in the Atlantic, Pacific, and Southern Oceans during the transition from the mid-Pliocene warm period to the onset of Northern Hemisphere glaciation (~2.5 to 3.5 million years before present). The new records will improve our understanding of the response of the deep ocean to the mid-Pliocene warmth and provide valuable insights into the ocean sensitivity to warmer/higher pCO2 conditions and during the subsequent transition to overall cooler climates in the Northern Hemisphere.In addition to better understanding links between the oceans and climate in a past analog to modern conditions, broader impacts include education and training of a female post-doctoral fellow and research opportunities for undergraduate students. The results will be presented in seminars, at national professional meetings, and incorporated into teaching curricula at undergraduate and graduate levels. The datasets generated in this research will be made available through the NOAA-NCDC web site.
温暖的上新世中期,全球平均气温比现在高2-3摄氏度,在政府间气候变化专门委员会(IPCC)对21世纪全球变暖的预测范围内,因此为未来气候变化提供了一个很好的模拟。这项工作由罗格斯大学的一组科学家进行,将产生新的地球化学代用记录。(Mg/Ca、B/Ca和Neo-Ca同位素组成),这将对大西洋、太平洋、从上新世中期温暖期到北方半球冰川作用开始(距今约250万年至350万年)的过渡期间,新记录将提高我们对深海对上新世中期温暖的反应的理解,并为海洋对温暖/较高pCO 2条件的敏感性以及随后向北方半球整体较冷气候的过渡提供有价值的见解。除了更好地理解海洋和气候之间的联系,在过去模拟现代条件,更广泛的影响包括教育和培训一名女博士后研究员以及为本科生提供研究机会。研究结果将在研讨会和全国专业会议上介绍,并纳入本科和研究生课程。这项研究所产生的数据集将通过诺阿-NCDC网站提供。
