项目摘要
Paleoceanographic records provide a unique opportunity to understand how ecosystems have responded to rapid environmental change in the past, a topic of significant societal and scientific interest. This project will document ecological changes in nearshore environments over the past several thousand years in Southern California, including investigation of impacts of both past and modern climate change. This work is of particular importance because these coastal ecosystems play critical roles in carbon sequestration, marine fisheries, coastal economies, and cycling of nutrients. As part of an integrated effort, the California Academy of Sciences (CAS) will catalog, digitize and identify fossil samples collected along the California margin. These materials will be combined with samples from available sediment cores to develop a public online digital database through which the research community may access project data and results. Two graduate students per year from the University of California Davis (UCD) will work closely with CAS staff to receive training in core curation and database development. In addition, this project supports the training of two Ph.D. students, and undergraduate research interns at UC Davis and UC Santa Barbara. The project also supports intensive field and laboratory based coursework and mentored research at Bodega Marine Laboratory for two undergraduates per year who are pursuing careers in K-12 STEM teaching. A research blog will be generated to develop scientific communication and writing skills in undergraduate, graduate students and technicians involved in this project. To complete this research, the research team will use sediment records from along the California margin to address two key questions: 1) How did the development of the modern oxygen minimum zone during the Holocene influence marine ecosystems, including multiple stages of perturbation and recovery? 2) Can we identify the marine ecological impacts of the Anthropocene, against a background of decadal-centennial scale variability? The team will utilize recent marine sediments to reconstruct marine microfossil response to both natural and anthropogenic environmental perturbation. This research will utilize a suite of available sedimentary archives (over 20 piston, box and multi cores), with moderately high sedimentation rates and available geochemical records, to identify and interpret metazoan and protistan assemblages. Microfossil assemblages will provide a framework to understand past, modern and future climate and oceanographic processes along the California margin. These results can be directly compared to modern instrumental records, and utilized to better predict future impacts of environmental change in this region.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.
古文学记录提供了一个独特的机会,可以理解过去对过去的迅速环境变化的反应,这是一个重要的社会和科学兴趣的话题。 该项目将记录过去几千年来南加州近岸环境的生态变化,包括调查过去和现代气候变化的影响。这项工作尤其重要,因为这些沿海生态系统在碳封存,海洋渔业,沿海经济体和养分循环中起着至关重要的作用。作为一项综合工作的一部分,加利福尼亚科学院(CAS)将分类,数字化和识别沿加利福尼亚利润率收集的化石样品。这些材料将与来自可用沉积物核心的样本结合使用,以开发一个公共在线数字数据库,研究界可以通过该数据库访问项目数据和结果。加利福尼亚大学戴维斯大学(UCD)每年的两名研究生将与CAS员工紧密合作,以接受核心策划和数据库开发的培训。此外,该项目还支持培训两个博士学位。学生,以及加州大学戴维斯分校和加州大学圣塔芭芭拉分校的本科研究实习生。该项目还支持基于实验室的密集课程和基于实验室的课程,并在Bodega Marine Laboratory进行了研究,每年为两名本科生从事K-12 STEM教学的职业。将生成一个研究博客,以发展本科生,研究生和技术人员的科学沟通和写作技巧。为了完成这项研究,研究团队将使用加利福尼亚利润率的沉积物记录来解决两个关键问题:1)全新世期间现代氧气最小区域的发展如何影响海洋生态系统,包括扰动和恢复的多个阶段? 2)我们能否确定人类世的海洋生态影响,与十年级量表变异性的背景?该小组将利用最近的海洋沉积物来重建对天然和人为环境扰动的海洋微化石反应。这项研究将利用一套可用的沉积档案(超过20个活塞,盒子和多核),具有中等高的沉积速率和可用的地球化学记录,以识别和解释过失和普通的集合。微(化石组合将提供一个框架,以了解加利福尼亚沿线沿线的过去,现代和未来的气候和海洋学过程。可以将这些结果直接与现代工具记录进行比较,并用于更好地预测该地区环境变化的未来影响。该奖项反映了NSF的法定任务,并使用基金会的知识分子优点和更广泛的影响评估审查标准,被认为值得通过评估来提供支持。
