Fundamental shifts in the Earth's ocean ecosystems and carbon cycle are currently underway due to anthropogenic processes, and the implications of these shifts are still poorly understood. Paleoceanographic records provide a unique opportunity to understand how ecosystems have responded to rapid climate change in the past. This work, led by a faculty member at the University of California at Davis, will utilize exquisite sediment records from Santa Barbara Basin (SBB) to reconstruct how seafloor biodiversity responded to changes in temperature and oxygenation during past time periods of rapid warming. This project builds upon the recent discovery that a wide variety of invertebrate taxonomic groups, including arthropods, molluscs, and echinoderms, are abundantly preserved in SBB sediments, and thus can be directly compared to more established records of climate change. The investigations of sedimentary communities will focus on three areas: 1) modern fauna, using recently collected box cores that span 300-1200m on the California margin, 2) a depth transect of cores from SBB spanning the deglaciation, the most abrupt climate change in recent geologic history, and 3) Mid-Pleistocene sediment records that have provided evidence of pervasive millennial-scale climate change throughout the past 1 Ma. A key to understanding the complexities of climate change impacts on ocean environments is the synthesis of biological, geological, chemical and physical information. This research will directly tackle that integration, and be combined with an effort to educate future math and science teachers and K-12 students by collaborating with the successful UC Davis Math and Science Teaching (MAST) program. Each year, MAST students will develop, test, and modify climate science curriculum during the fall, which will then be utilized for visiting classrooms the following spring. Summer Fellowships will provide full financial support for MAST students (2/year) to take summer intensive field courses at Bodega Marine Laboratory (BML) and complete independent research projects. At the completion of their MAST Fellowship, students will utilize their independent research projects and data as inspiration for the next round of MAST-student led curriculum development.

由于人为过程，目前正在进行地球海洋生态系统和碳周期的基本转变，并且这些转变的含义仍然很少了解。古文学记录提供了一个独特的机会，可以理解生态系统过去对过去的快速气候变化的反应。这项工作由加州大学戴维斯分校的一名教职员工领导，将利用圣塔芭芭拉盆地（SBB）的精美沉积物记录来重建在过去快速变暖的过去时间中，海底生物多样性如何应对温度和氧合的变化。该项目基于最近的发现，即包括节肢动物，软体动物和棘皮动物在内的各种无脊椎动物分类群体在SBB沉积物中得到了大量保存，因此可以直接将其与更具成熟的气候变化记录进行比较。对沉积社区的调查将重点关注三个领域：1）现代动物群，使用最近收集的盒子核心​​，在加利福尼亚的边缘占300-1200m，2）跨越SBB的深度层次跨越脱发的深度样品，这是最近的地球史上最突然的杂物变化，以及3）中等境界的证据。了解气候变化对海洋环境的影响的关键是生物，地质，化学和物理信息的综合。这项研究将直接解决该集成，并通过与成功的UC Davis数学和科学教学（MAST）计划合作来教育未来的数学和科学教师以及K-12学生。每年，桅杆学生都会在秋季开发，测试和修改气候科学课程，然后在第二个春季将其用于访问教室。夏季奖学金将为桅杆学生（2/年）提供全面的财政支持，以参加Bodega Marine Laboratory（BML）的夏季强化野外课程并完成独立的研究项目。完成桅杆奖学金后，学生将利用其独立的研究项目和数据作为下一轮桅杆学生LED课程开发的灵感。
