Ocean circulation and the ice-temperature conundrum: Unraveling the transition from the Cretaceous greenhouse into today's icehouse world

海洋环流和冰温难题:揭示从白垩纪温室到当今冰库世界的转变

基本信息

项目摘要

The overall goal of this proposal is to reconstruct temperature and ice-volume changes and their effects on ocean circulation and marine ecosystems for specific time intervals of the past 100 Ma that are particularly critical for our understanding of the Earth’s paleoclimatic dynamics. To tackle controversially discussed paleoclimatic and paleoceanographic issues, the proposed project will employ the novel carbonate “clumped-isotope” paleothermometer (CCIP), a new paleo-oxygenation proxy based on benthic foraminiferal pore characteristics (BFPC), and foraminiferal assemblage data. The overall project goals will be achieved following a threestage approach that comprises (I) testing of CCIP and BFPC, (II) the calibration of both proxies for selected foraminiferal taxa, and (III) their employment in studies on selected time slices of the Ceno- and Mesozoic. Stage (III) will comprise seven case studies where CCIP and BFPC analyses will be combined with “classical” proxies (e.g., δ18O, Mg/Ca, and assemblage counts). This integrated approach will allow to separate temperature from ice/salinity signals and to decipher the respective effects on ocean circulation and ecosystems, which will yield new insights into controversially discussed paleoclimatic and paleoceanographic processes. The proposed research can ultimately provide a significant step forward towards resolving the icetemperature conundrum for the Cretaceous greenhouse to the present-day’s icehouse world.
该提案的总体目标是重建过去100 Ma特定时间间隔内的温度和冰量变化及其对海洋环流和海洋生态系统的影响,这对我们了解地球古气候动力学尤为重要。为了解决有争议的古气候和古海洋学问题,本项目将采用新型碳酸盐“块状同位素”古温度计(CCIP)、基于底栖有孔虫孔隙特征(BFPC)和有孔虫组合数据的新古氧合代用指标。总体项目目标将通过三个阶段的方法来实现,包括:(1)测试CCIP和BFPC,(2)校准选定有孔虫类群的两个代理,以及(3)在选定的新生代和中生代时间片的研究中使用它们。阶段(III)将包括七个案例研究,其中CCIP和BFPC分析将与“经典”代理(例如δ18O, Mg/Ca和组合计数)相结合。这种综合方法将允许分离温度和冰/盐度信号,并破译各自对海洋环流和生态系统的影响,这将对有争议的古气候和古海洋学过程产生新的见解。这项提议的研究最终将为解决白垩纪温室到当今冰窖世界的冰温难题迈出重要的一步。
