GeoSystems: Probing Earth's Deep-Time Climate and Linked Systems

GEOSYSTEMS：探测地球的深时气候和相关系统gerilyn Soreghan，俄克拉何马大学christopher Maples，沙漠研究所GEOSYSTEMS是一个正在发展的基于社区的项目，主要关注以气候为重点的深时视角对理解地球大气、水圈、生物圈和地表岩石圈的复杂性的重要性。地球气候在时间、空间和参数尺度的连续体上运行，是变化的基本中介。深时地质记录保存了许多过去气候状态和转变的代用物，其中许多比仪器记录、历史记录或第四纪记录中记录的要极端得多。了解全球系统中这些极端现象的范围、速率和过程对于预测这些变化的潜在影响至关重要。诸如物种灭绝和进化、造山和岩浆活动、海平面变化等过程在各种时间尺度上发生作用，并与气候趋势复杂地交织在一起，其中许多过程也在各种时间尺度上发生作用，必须在深时间视角的背景下进行观察。拟议中的GeoSystems计划只有通过数据增强和地球、海洋和大气建模研究人员之间的建模合作才能取得进展，重点关注深时间记录，以实现对地球气候和相关系统的全面了解。在本次研讨会上，来自不同学科（如沉积学/地层学、无机和有机地球化学、古生物学、气候模拟、地貌学、构造学、海洋地质学、地质年代学）的与会者将齐聚一堂，讨论并制定一个愿景和初步科学计划，以实现地球系统研究和教育的巨大飞跃。本次研讨会将有助于对深时气候和相关系统研究做出明智的决策，从而从深时气候的角度提高集体对地球系统行为的认识和理解。

GEOSYSTEMS: PROBING EARTH'S DEEP-TIME CLIMATE & LINKED SYSTEMSGerilyn Soreghan, University of OklahomaChristopher Maples, Desert Research InstituteEAR-0427093ABSTRACTGeoSystems is a developing community-based initiative that focuses on the importance of the deep-time perspective for understanding the complexities of Earth's atmosphere, hydrosphere, biosphere and surficial lithosphere using climate as the focus. Earth's climate operates on a continuum of temporal, spatial and parametric scales, as a fundamental mediator of change. The deep-time geologic record preserves numerous proxies of past climate states and transitions, many of which are far more extreme than those archived in instrumental, historical, or Quaternary records. Understanding the ranges, rates, and processes responsible for these extremes in global systems is critical for predicting potential impacts of such changes. Processes such as extinction and evolution of species, orogenic and magmatic events, sea-level change, and the like operate over a variety of time scales and are complexly entwined with climatic trends, many of which also operate over a variety of time scales and must be viewed within the context of the deep-time perspective. The proposed GeoSystems initiative will be able to progress only through data enhancements and modeling collaborations among earth, ocean, and atmospheric-modeling researchers, focusing on the deep-time record to achieve a holistic understanding of Earth's climate and related systems. At this workshop, participants from various disciplines (e.g., sedimentology/stratigraphy, inorganic and organic geochemistry, paleontology, climate modeling, geomorphology, tectonics, marine geology, geochronology) will convene to discuss and formulate a vision and an initial science plan to enable a quantum leap in the pursuit of GeoSystems research and education. This workshop will contribute to informed decision-making on deep-time climate and related systems research and thus raise collective awareness and understanding of Earth System behavior as viewed from the deep-time climate perspective.
