Workshop Proposal: Defining Grand Challenges in Sedimentary Geology & Paleobiology

确定沉积地质学和古生物学中的重大挑战召集人：Isabel Montañez（加州大学戴维斯分校）& Charles Marshall（加州大学伯克利分校）abstract地球？地球的表面地壳承载着(1)我们的矿物、碳氢化合物和水资源；(2)过去气候变化的全谱记录；(3)在过去各种条件下生态系统变化的幅度和速度的自然实验室；(4)生命进化史的档案，包括整个地球的生物多样性和进化创新。(5)记录导致自然灾害（如地震、洪水、火山爆发）的过程或对其作出反应的过程。对这些和相关问题的科学调查主要是沉积地质学家、地球化学家和古生物学家的职权范围，他们之间的合作越来越多。最近在沉积地质学和古生物学（SGP）方面的科学努力在地质记录的辐射校准和我们对深时间地球过程的解释性理解方面取得了显著进展，这些过程不能从地球以外的任何其他档案中推断出来。地壳外壳。尽管取得了这些进展，但在过去的十年或更长时间里，SGP社区并没有召开会议，讨论和制定SGP范围内的一致愿景，以便在我们更广泛的学科领域进行未来的研究。此外，支持SGP研究的资金水平越来越不足，限制了对令人兴奋的新科学机会和方向的追求，以及支持研究和指导活动所需的智力、文化和技术基础设施的发展。pi建议举办研讨会，让SGP各分支学科的代表进行思想交流，以确定沉积地质学和地球化学、深时古气候学和古生物学等领域未来需要解决的关键研究问题和主题。研讨会的三个主要目标是：(1)确定沉积、地球化学和古生物记录提供的高优先级和新兴的研究机会；(2)制定并优先考虑一套指导？大挑战?(3)描述支持这些新兴研究机会所需的关键仪器和设施。

Defining Grand Challenges in Sedimentary Geology & Paleobiology Conveners: Isabel Montañez (University of California, Davis) & Charles Marshall (University of California, Berkeley) ABSTRACTThe Earth?s surface crust is host to (1) our mineral, hydrocarbon and water resources, (2) a full-spectrum record of past climate change, (3) a natural laboratory of the magnitude and rates of change in ecosystems under the range of past conditions, (4) the archive of the evolutionary history of life, including biodiversity and evolutionary innovation throughout Earth?s history, particularly during times of rapidly changing environmental conditions, and (5) a record of the processes that lead to or respond to natural hazards such as earthquakes, flooding, volcanic eruptions. Scientific investigation into these and related issues is primarily the purview of sedimentary geologists and geochemists and paleontologists - increasingly working in collaboration. Recent scientific efforts in sedimentary geology and paleobiology (SGP) have led to notable advances in radiometric calibration of the geologic record and in our interpretive understanding of deep-time earth processes that cannot be inferred from any other archive than the Earth?s crustal carapace. Despite these advances the SGP community has not convened in the past decade or more to discuss and develop a SGP-wide and coherent vision for the future of research in our broader disciplinary field. Furthermore, funding levels to support SGP research are increasingly inadequate limiting the pursuit of exciting new scientific opportunities and directions as well as the development of intellectual, cultural and technical infrastructure needed to support research and mentoring activities. PIs propose a workshop for the exchange of ideas among representatives of the various sub-disciplines in SGP in order to identify key research questions and topics in sedimentary geology and geochemistry, deep-time paleoclimatology, and paleobiology that need to be addressed by the community through future research. The three primary objectives of the workshop are (1) to identify high-priority new and emerging research opportunities offered by the sedimentary, geochemical and paleontological records, (2) to develop and prioritize a set of guiding ?grand challenges? for the coming decade of research in the aforementioned sub-disciplines, and (3) delineate key instrumentation and facilities that will needed to support these new and emerging research opportunities.
