This CAREER award will support research and education activities designed to (1) improve understanding of Earth's transition out of the late Paleozoic ice age (LPIA) and (2) communicate the significance of Earth systems history to the general public. Research activities will integrate sedimentological, petrographic, and stable isotopic investigations of Early Permian marine carbonate deposits to improve understanding of the climatic, oceanographic, and ecological changes that accompanied Earth's transition from a deep icehouse to a prolonged greenhouse climate mode. The project will build upon ongoing collaborative work on late Paleozoic strata of eastern Australia, which has resulted in a chronostratigraphic framework tied directly to glaciation. Emphasis will be placed on developing carbon and oxygen isotope profiles that will help to establish the relative timing and character of changes in sea level, climate, and oceanography along a paleolatitudinal transect. Education activities will center around an annual, field-oriented summer course, "History on the Rocks," designed for high school teachers and 9th-10th grade students. The course will focus on climate change and catastrophes in Earth history, as illustrated by a series of world-class geological field sites in Nebraska. The project will result in up to four graduate-level and four undergraduate senior theses. Because the project integrates field and laboratory components, students will amass a broad range of experiences and training in sedimentology, stratigraphy, and geochemistry. In addition to research, UNL students will be expected to help with logistical and educational aspects of "History on the Rocks." They will also help to develop a display and hands-on activity based on research results for an annual family day at the UN State Museum. These activities will provide the UNL students with valuable experience in teaching science and communicating research results to the public. "History on the Rocks" will directly impact up to 15 high school science teachers and 45 9th-10th grade students from across Nebraska, and indirectly affect many more. The course will be offered four times for specific audiences. Two sessions will cater to groups historically under-represented in the geosciences: females and Native Americans. Through activities that incorporate a scientific approach, participants will gain an appreciation of the scientific method, the geoscience profession, and the societal significance of geoscience research.

该职业奖将支持旨在（1）提高对地球晚期过渡（LPIA）过渡的理解的研究和教育活动，（2）将地球系统历史的重要性传达给公众。研究活动将整合早期二叠纪海洋碳酸盐沉积物的沉积学，岩石学和稳定的同位素研究，以提高对地球从深层冰屋过渡到延长温室气候模式的过渡的气候，海洋学和生态变化的理解。该项目将基于在澳大利亚东部已故古生代地层进行的持续合作工作，这导致了直接与冰川化有关的年度地层学框架。将重点放在开发碳和氧同位素剖面，这将有助于建立沿着古列展沿沿着海平面，气候和海洋学变化的相对时机和特征。教育活动将围绕着年度面向野外的夏季课程，“岩石的历史”，该课程专为高中教师和9至10年级的学生而设计。该课程将集中在地球历史上的气候变化和灾难上，如内布拉斯加州的一系列世界一流地质田地所示。 该项目最多将导致四个研究生级和四个本科高级论文。由于该项目集成了现场和实验室组件，因此学生将在沉积学，地层学和地球化学方面积累广泛的经验和培训。除了研究外，还应期望UNL学生帮助“岩石历史”的后勤和教育方面。他们还将根据在联合国州立博物馆举行的一年一度家庭日的研究结果来帮助开发展示和实践活动。这些活动将为UNL学生提供在教授科学和向公众传达研究结果的宝贵经验。 “岩石历史”将直接影响来自内布拉斯加州各地的15名高中科学老师和45名9至10年级的学生，并间接影响更多。该课程将为特定受众提供四次。两次会议将迎合地球科学中历史上代表不足的群体：女性和美洲原住民。通过结合科学方法的活动，参与者将对科学方法，地球科学专业以及地球科学研究的社会意义获得赞赏。
