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

地球系统：探索地球的深层时间气候联系的EMSGerilyn Soreghan，俄克拉荷马大学克里斯托弗梅普尔斯，沙漠研究所EMS-0427093摘要地球系统是一个发展中的社区为基础的倡议，重点是深时间的角度理解地球的大气层，水圈，生物圈和地表岩石圈的复杂性，以气候为重点的重要性。 地球气候在时间、空间和参数尺度上连续运作，是变化的基本媒介。深时地质记录保存了过去气候状态和转变的许多代理，其中许多比仪器，历史或第四纪记录中的记录要极端得多。了解全球系统中这些极端事件的范围、速率和过程对于预测这些变化的潜在影响至关重要。物种灭绝和进化、造山和岩浆事件、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联系在一起，其中许多过程也在各种时间尺度上发生作用，必须从深时角度加以看待。拟议中的GeoSystems计划将只能通过地球，海洋和大气建模研究人员之间的数据增强和建模合作来取得进展，重点是深时间记录，以实现对地球气候和相关系统的整体理解。在这次研讨会上，来自不同学科的与会者（例如，将召开一次会议，讨论和制定一个愿景和一个初步的科学计划，以实现在追求地球系统研究和教育方面的巨大飞跃。本次研讨会将有助于深时气候和相关系统研究的知情决策，从而提高从深时气候角度来看地球系统行为的集体意识和理解。

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.
