Abstract Deep ocean sediments document past environmental changes over space and time. The information gleaned from such deposits allows scientists to test climate models that are used to predict future climate change. However, the causes and consequences of changing climate can be unraveled only if geological data from different regions are synchronized in time so that lead‐lag relationships can be properly established. Synchronization of geological archives across regions requires precise and accurate age models, but available age models are often not sufficiently accurate to rigorously test causality arguments. We therefore propose to launch an international, coordinated effort to revise and recalibrate the dating tools available to paleoclimatologists—that is, the local and regional information obtained from bio‐, magneto‐, and chemo‐stratigraphy as well as radioisotopic geochronology—with the synchronizing tool of astrochronology. Cross‐fertilization of expertise is needed to generate new age models for sediment records from which key climate events have been or can be reconstructed. We expected this initiative could make a significant contribution to the understanding of Earth history, biotic evolution, and particularly, Earth's climate history.

Paleoceanography and Paleoclimatology

古海洋学和古气候学 (PALO) 发表有关过去环境、生物群和气候记录的论文。了解过去的地球系统需要采用广泛的方法，包括海洋和湖泊沉积学和洞穴岩浆；冰盖的形成和流动；稳定同位素、微量元素和有机地球化学；古生物学和分子古生物学；进化过程；生物体中的矿化；了解树木年轮的形成；地震地层学；物理、化学和生物海洋学；地球化学、气候和地球系统建模等。该期刊的范围是区域性到全球性的，而不是地方性的，并且包括任何地质时代的研究（前寒武纪到第四纪，包括现代类似物）。在这个框架内，将包括以下主题的论文：年代学、地层学（与古海洋学事件的相关性相关）、古构造、古海洋学建模、古循环（深、中、浅）、古气候学（例如，古风和冰冻圈历史)、全球沉积物和地球化学循环、缺氧、海平面变化和影响、生物进化与古海洋学之间的关系、生物危机、古生物学（例如，古海洋学中使用的“微化石”生态学）、古海洋学推断中的技术和方法，以及现代古海洋学类似物，以及耦合海洋-大气-生物圈过程的定量和综合分析。古海洋学和古气候研究使我们能够利用过去来获取有关未来可能的气候和生物发展的信息：过去是未来的关键，与现在相比，过去是过去的关键。

The journal "Paleoceanography and Paleoclimatology" publishes research papers on ancient environments, biomes, and climate records. Understanding past Earth systems requires a wide range of approaches, including marine and lake sedimentology, cave magma studies, the formation and flow of ice sheets, stable isotope analysis, trace elements and organic geochemistry, paleobiology and molecular paleobiology, evolutionary processes, mineralization phenomena, tree-ring formation, seismic stratigraphy, physical, chemical, and biological oceanography, geochemistry, climate, and Earth system modeling. The scope of the journal ranges from regional to global studies, covering research from any geological era (Precambrian to Quaternary, including modern analogs). Within this framework, the journal welcomes papers on the following topics: chronology, stratigraphy (related to paleoceanographic events), paleotectonics, paleoceanographic modeling, paleocirculation (deep, intermediate, shallow), paleoclimatology (e.g., ancient winds and cryosphere history), global sediment and geochemical cycles, anoxia, sea-level changes and impacts, the relationship between biological evolution and paleoceanography, biotic crises, paleobiology (e.g., the ecology of microfossils used in paleoceanography), techniques and methods in paleoceanographic inference, as well as modern paleoceanographic analogs, and quantitative and integrative analyses of coupled ocean-atmosphere-biosphere processes. Paleoceanography and paleoclimate studies enable us to leverage past information to gain insights into potential future climate and biological developments: the past is key to the future, and understanding the past is crucial for our present.
