Collaborative Research: GeoChronR - Open-source Tools for the Analysis, Visualization and Integration of Time-Uncertain Geoscientific Data

这项来自地球科学部地理信息学项目的合作资助将支持软件工具的开发，使地球科学家能够更好地量化和分析年龄的不确定性如何影响过去的气候、生态系统和景观记录。这些工具将使科学家能够更好地整合这些记录，并将更大的数据集整合到预测模型中。因此，这些工具将有助于更彻底地了解过去的气候变化，并对有关地球的假设进行更严格的测试。年代的历史。将举行两个讲习班，以确保可能从这些工具中受益的科学家群体获得培训和机会，以便对软件开发过程提供反馈。具体来说，研究人员将开发一套集成软件工具，并使用开源和社区支持的平台R使这些工具广泛可用。这些工具将使古地球科学家能够使用最先进的贝叶斯和蒙特卡罗方法来量化古记录中的年龄不确定性，并允许更严格地整合数据集和模型，更彻底地考虑年龄不确定性。这些工具将允许广泛的古地球科学研究人员以直观和一致的方式可视化和存档他们的数据。研究人员将把这些工具应用于概念验证数据恢复工作，旨在为海洋和陆地的全新世古气候记录存档主要的地质年代学信息，从而为美国国家科学基金会地球系统历史（ESH）全新世计划的结果提供一个综合和更永久的存档。

This collaborative grant from the Division of Earth Sciences Geoinformatics program will support the development of software tools which will enable Earth scientists to better quantify and analyze how uncertainties in ages influence records of past climate, ecosystems and landscapes. These tools will allow scientists to better integrate these records, and to integrate larger datasets into predictive models. Thus, the tools will facilitate a more thorough understanding of past climate changes, and more rigorous tests of hypotheses regarding Earth?s history. Two workshops will be held to ensure that the community of scientists who may benefit from these tools are provided with training and opportunities to provide feedback to the software development process. Specifically, the researchers will develop a package of integrated software tools and make these tools broadly available using the open-source and community supported platform ?R?. The tools will enable paleogeoscientists to use state-of-the-art Bayesian and Monte-Carlo-based approaches to quantifying age uncertainties in paleorecords, and allow more rigorous integration of data sets and models with more thorough accounting for age uncertainties. The tools will allow the broad community of paleogeoscience researchers to visualize and archive their data in intuitive and consistent ways. The researchers will apply the tools to a proof-of-concept data recovery effort aimed at archiving primary geochronological information for marine and terrestrial records of Holocene paleoclimate, thereby providing a synthesis and more permanently archive of results from the NSF Earth System History (ESH) Holocene initiative.
