Collection and analysis of seafloor sediment samples is a fundamental tool in marine geology. Sediment sampling is key to the study of earthquake hazards, climate change, and the deep biosphere. This project will focus on training scientists for seafloor sampling best practices. Practices encompass planning and executing an oceanographic field expedition involving collection of deep-sea marine sediments. The shore-based training will introduce participants to critical aspects of cruise planning and site selection. Such selection uses basic geophysical techniques, access to data, and use of core repositories. Participants will design a science-driven cruise plan with guidance from an experienced team of mentors. Then, the participants will sail on a UNOLS global class vessel to gain hands-on experience. The experience includes working with site survey, sampling equipment, and shipboard data collection. The training will conclude ashore with a review of the scientific outcomes of the cruise. The post-cruise component will allow for hands-on training. The training will include analytical, interpretive and archival techniques. The training will set the stage for efficient and successful future research using the collected materials. Participant selection will focus on promoting equity and diversity in marine geoscience. In August of 2019 a detailed survey was conducted to quantify interest in early career coring training for prospective NSF principal investigators. Nearly a hundred responses were submitted in a period of less than two weeks, highlighting community need and demand for a training opportunity that encompasses cruise planning, site selection, shipboard operations, core processing and curation. This proposal is to provide a sediment coring principal investigator (PI) training for early career scientists (ECS). Training will consist of a coupled workshop and field program: a field-based coring program of ten days aboard a UNOLS vessel to be directed by the early-career participants, bracketed by week-long pre-and post-cruise workshops. In the pre-cruise workshop participants will plan the cruise and select sites to be cored with the support and guidance of a team of experienced mentors. They will be trained in the utility of legacy data at the Oregon State University Marine Geology Repository (OSU MGR). They will also be introduced to the NSF Marine Sediment Sampling (MARSSAM) facility and the technical and logistical support offered to NSF coring PI’s by MARSSAM staff. At sea, participants will be trained in the operation and deployment of various coring systems, chirp and multi-beam data acquisition and interpretation, final site selection, core processing, multi-sensor core logger data collection and interpretation, and shipboard core description and curation. At the post-cruise workshop, senior mentors will guide participants through interpretation of core descriptions, integration of collected cores and preliminary physical property data with the stratigraphic/depositional environment. Participants will also be introduced to relevant analytical techniques and appropriate archival, sampling and data management practices.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.

海底沉积物样本的收集和分析是海洋地质学的基本工具。沉积物取样是研究地震灾害、气候变化和深层生物圈的关键。该项目将重点培训科学家掌握海底取样的最佳做法。实践包括计划和执行涉及深海海洋沉积物收集的海洋实地考察。岸上培训将向参与者介绍巡航计划和地点选择的关键方面。这种选择使用基本的地球物理技术，访问数据和使用核心存储库。参与者将在经验丰富的导师团队的指导下设计科学驱动的巡航计划。然后，参与者将乘坐联索特派团的全球级船只航行，以获得实践经验。工作经验包括现场调查、取样设备和船上数据收集。培训将在岸上结束，并回顾这次巡航的科学成果。后巡航组件将允许动手培训。培训将包括分析、解释和档案技术。培训将为利用收集到的材料进行有效和成功的未来研究奠定基础。参与者的选择将侧重于促进海洋地球科学的公平性和多样性。2019年8月，进行了一项详细的调查，以量化对未来国家科学基金会首席研究员早期职业核心培训的兴趣。在不到两周的时间内，提交了近100份回应，突出了社区对培训机会的需求，包括巡航规划、选址、船上操作、核心处理和管理。本提案旨在为早期职业科学家（ECS）提供沉积物取心首席研究员（PI）培训。培训将包括一个讲习班和实地方案：在联索特派团的一艘船上进行为期十天的实地取心方案，由职业生涯初期的参与者指导，其间还有为期一周的巡航前和巡航后讲习班。在航行前的工作坊中，参加者将在经验丰富的导师团队的支持和指导下规划航行和选择地点。他们将在俄勒冈州立大学海洋地质储存库（OSU MGR）接受使用遗留数据的培训。他们还将被介绍到美国国家科学基金会海洋沉积物采样（MARSSAM）设施，以及MARSSAM工作人员为美国国家科学基金会取心PI提供的技术和后勤支持。在海上，参与者将接受各种取心系统的操作和部署、啁啾和多波束数据采集和解释、最终地点选择、岩心处理、多传感器岩心记录器数据收集和解释以及船上岩心描述和管理方面的培训。在巡航后的研讨会上，资深导师将指导参与者解释岩心描述，将收集到的岩心和初步物性数据与地层/沉积环境相结合。还将向参加者介绍有关的分析技术和适当的档案、抽样和数据管理做法。该奖项反映了美国国家科学基金会的法定使命，并通过使用基金会的知识价值和更广泛的影响审查标准进行评估，被认为值得支持。
