This project draws together scholarship from history and geography to uncover the history of scientific research on ice and how it has been used by naturalists and scientists to understand geological timescales and to predict future ecological change. Evidence extracted from ice has fundamentally recalibrated scientific conceptions of earth's deep history: the theory of the Ice Ages revealed the planet's radical changeability, and evidence from ice cores showed a globe that rapidly flickers between different meteorological states. Data for the project will come from documents gathered at national archives in the United States, the United Kingdom, and Germany, and these will be complimented by analyses of published scientific papers and visual materials. Overall, this project traces our changing scientific conceptions of ice over the past two hundred years to highlight its importance for advancing scientific understanding of the planet as an interconnected system with a deep past and a deep future.This is an investigation into the cryosphere - those portions of the Earth's surface that are covered in solid ice - and into the ways in which scientists have studied and conceptualized it over the past two hundred years. Analyses of ice have provided critical ecological data that has enabled scientists to appreciate the true depth of the Earth's history and to understand patterns of environmental change and systematic meteorological variability over time. Data for this multi-method project come from collections at several national archives and from historically relevant scientific papers and visual models. Systematic qualitative documentary analysis will be used to analyze these data and enhance our understanding of how research on the cryosphere has shaped our collective understanding of the environmental history and future of Earth.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目将奖学金从历史和地理学中汇集在一起​​，以揭示冰的科学研究史以及博物学家和科学家如何将其用于理解地质时代尺度并预测未来的生态变化。从冰中提取的证据从根本上重新校准了地球深层历史的科学概念：冰河时代的理论揭示了地球的根本性变化性，冰核的证据显示了一个地球仪，该地球仪在不同的气象状态之间迅速闪烁。该项目的数据将来自收集在美国国家档案馆，英国和德国的文件，这些文件将通过对发表的科学论文和视觉材料的分析来称赞。总体而言，该项目在过去的两百年中追溯了我们不断变化的冰的科学概念，以突出其对地球作为一个具有深厚过去和深层未来的相互联系的系统的科学理解的重要性。这是对冰冻圈的调查 - 地球表面的那些部分是扎实的冰层，并涵盖了扎实的冰层 - 以及科学家已经研究并概念化了两百年来的科学家。对冰的分析提供了关键的生态数据，使科学家能够欣赏地球历史的真实深度，并了解环境变化和随时间变化的系统变化的模式。这个多方法项目的数据来自几个国家档案馆的收藏品，以及历史相关的科学论文和视觉模型。系统的定性文献分析将用于分析这些数据，并增强我们对Cryosphere的研究如何塑造我们对地球环境历史和未来的集体理解。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛影响的审查标准来通过评估来支持的。
