ITR/AP\(EAR) Collaborative Research: Web tools for global time scale development: an example from the Pennsylvanian-Cisuralian\(Early Permian\)(EAR-0218799)Vladimir Davydov, C. J. Northrup, Tamra SchiappaBoise State UniversityABSTRACT"Web Tools for Global Time Scale Development: an Example from the Pennsylvanian-Cisuralian (Early Permian)" is an information technology project that deals with the development of the geologic time scale. The geologic time scale is a fundamental tool of Earth Science research. The correlation of global events and the calculation of rates of processes during Earth's history all depend directly on the accuracy and precision of the geologic time scale. These processes include, for example, the rates and causes of extinction, climate change, plate motions, and mountain building. Despite its critical role, portions of the time scale have not been formally defined. The focus of this project will be twofold: 1) to develop a method that will serve as a model for international discussion and agreement on the development of a complete time scale, and 2) to use a particular part of the time scale that is presently undefined, as an example of how to achieve this goal. Specifically, PIs will develop Web-based tools that will facilitate the international debate for establishment of the Pennsylvanian and Early Permian stage boundary definitions, and that will serve as a permanent resource for the data utilized for these definitions. This tool will allow all interested workers to easily enter and extract a wide variety of data from a system that is global in extent. The time scale is based on the succession of fossils that are preserved in the stratigraphic record, and therefore, these data will include a wealth of information on paleontology and biostratigraphy. The ability to interact with these data and other researchers over the Internet will help resolve issues about the terminology for specific species, and hence remove fundamental road blocks to international agreement. The system must also accommodate information about the stratigraphy - the architecture of the succession of sedimentary rocks - that are the hosts for the fossil record. It must also include so-called absolute ages of rocks based on radiometric dating. Various geochemical, paleomagnetic and other data must be included to form a true systems approach to building the time scale. By combining these and other data types into a single system, PIs hope to be able to, for the first time, develop a reliable approach to the development of the geologic time scale.

ITR/ap \（EAR）协作研究：全球时间尺度开发的网络工具：宾夕法尼亚州 - 库尔西斯神秘主义者\（早期二叠纪\）（EAR-0218799）Vladimir Davydov，C。J。Northrup，C。J。Northrup，Tamra Schiappaboise State time Sparts for Global Time Sparts（tamra schiappaboise for Global Time Spart）：一个涉及地质时间尺度发展的信息技术项目。地质时间尺度是地球科学研究的基本工具。全球事件的相关性和地球历史上过程速率的计算完全取决于地质时间尺度的准确性和精度。这些过程包括例如灭绝的速度和原因，气候变化，板块运动和山区建筑。尽管它具有关键作用，但时间尺度的一部分尚未正式定义。该项目的重点将是双重的：1）开发一种方法，该方法将作为国际讨论和共同开发完整时间量表的模型，以及2）使用目前未定义的时间尺度的特定部分，以实现这一目标的示例。具体而言，PI将开发基于Web的工具，以促进建立宾夕法尼亚州和早期二叠纪阶段边界定义的国际辩论，并将作为用于这些定义的数据的永久资源。该工具将使所有感兴趣的工人可以轻松地从全球范围内的系统中输入和提取各种数据。时间尺度是基于在地层记录中保存的化石继承，因此，这些数据将包括有关古生物学和生物地层学的大量信息。通过互联网与这些数据和其他研究人员进行互动的能力将有助于解决有关特定物种术语的问题，从而消除国际协议的基本路障。该系统还必须容纳有关地层的信息 - 沉积岩石继任的建筑 - 是化石记录的宿主。它还必须包括基于辐射测定的所谓的岩石绝对年龄。必须包括各种地球化学，古磁和其他数据，以形成建立时间尺度的真实系统方法。通过将这些和其他数据类型相结合到单个系统中，PIS希望能够首次为地质时间尺度开发开发可靠的方法。
