项目摘要

Collaborative Research: Ocean Oxidation and the Biosphere during Neoproterozoic GlaciationSusannah Porter (Lead PI); EAR-0922305University of California Santa BarbaraMatthew Hurtgen; EAR-0921913Northwestern UniversityARRA Statement: "This proposal will be awarded using funds made available by the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).ABSTRACTAn increase in Earth surface oxygen levels has long been invoked as a driver of biological innovation at the end of the Neoproterozoic Era (1000 to ~541 million years ago), when diverse macroscopic life, including animals, first flourished. Recent work suggests that a pulse in ocean oxygenation ~580 million years ago may have permitted the evolution of animals, but almost no consideration has been paid to the relationship between biology and fluctuating oxygen levels earlier in the Neoproterozoic, in particular spanning the Cryogenian (a.k.a. ?snowball Earth?) glaciations ~720 to 635 million years ago, when Earth may have been entombed in ice. The aim of this project is two-fold: (1) reconstruct oxygen levels and biology during the Cryogenian glacial interval; and (2) test the hypothesis that fluctuating oxygen levels are linked to changes in the diversity and composition of biological communities observed during this time. To address these goals, the PIs will undertake micropaleontological, geochemical, and geochronologic analyses of shales collected from successions in Svalbard, an archipelago north of Norway, and in four separate basins in Australia. Collectively, these units span the entire interval of Cryogenian glaciation. Samples from Svalbard have already been collected; samples from Australia will be collected during two field seasons, one in Tasmania, the other on the Australian mainland. All analyses will be performed on the same suite of stratigraphically well-defined samples, allowing records of life and oxygen availability to be unambiguously linked and placed within the context of Neoproterozoic climate change.
合作研究:新元古代冰川时期的海洋氧化和生物圈Susannah Porter(首席研究员); EAR-0922305加州大学圣巴巴拉分校Matthew Hurtgen; EAR-0921913西北大学ARRA声明:“该提案将使用2009年美国复苏和再投资法案(公法111-5)提供的资金来授予。摘要长期以来,在新元古代末期(1000年至约5.41亿年前),地球表面氧气水平的增加一直被视为生物创新的驱动力,当时多种宏观生命,包括 动物,先繁盛。最近的研究表明,约 5.8 亿年前海洋氧合的脉冲可能允许动物进化,但几乎没有考虑到生物学与新元古代早期氧气水平波动之间的关系,特别是约 720 至 6.35 亿年前的低温期(又名“雪球地球”)冰川期,当时地球可能已被埋在冰中。目的 该项目有两个方面:(1)重建冰河期期间的氧气水平和生物学; (2)检验氧气水平波动与在此期间观察到的生物群落多样性和组成的变化有关的假设。为了实现这些目标,PI 将对从连续的页岩中收集的页岩进行微古生物学、地球化学和地质年代学分析。 斯瓦尔巴群岛是挪威北部的一个群岛,位于澳大利亚的四个独立盆地中。总的来说,这些单位跨越了整个成冰纪冰川期。斯瓦尔巴特群岛的样本已经采集;来自澳大利亚的样本将在两个野外季节收集,一个在塔斯马尼亚,另一个在澳大利亚大陆。所有分析都将在同一套地层明确定义的样本上进行,从而记录生命 和氧气的可用性明确地联系在一起,并置于新元古代气候变化的背景下。
