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.

海底沉积物样品的收集和分析是海洋地质学的一个基本工具。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。该项目的重点是培训科学家掌握海底取样的最佳做法。实践包括规划和执行海洋学实地考察，收集深海海洋沉积物。岸上培训将向参加者介绍巡航规划和选址的关键方面。这种选择使用基本的地球物理技术、获取数据和使用核心储存库。参与者将在经验丰富的导师团队的指导下设计一个科学驱动的巡航计划。然后，参与者将乘坐联合国海洋法办事处的全球级船只航行，获得实践经验。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，对巡航的科学成果进行审查。巡航后部分将允许进行实践培训。培训将包括分析、解释和档案技术。培训将为使用收集的材料进行有效和成功的未来研究奠定基础。参加者的挑选将侧重于促进海洋地球科学的公平性和多样性。在2019年8月进行了一项详细的调查，以量化未来NSF主要研究人员对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份答复，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。该建议是为早期职业科学家（ECS）提供沉积物取芯首席研究员（PI）培训。培训将包括一个讲习班和实地方案：在联合国海洋和海洋法办事处的船上进行为期十天的实地取芯方案，由职业生涯初期的参与者指导，其间还包括为期一周的巡航前和巡航后讲习班。在航行前研讨会上，参与者将在经验丰富的导师团队的支持和指导下规划航行并选择要取芯的地点。他们将在俄勒冈州州立大学海洋地质储存库（OSU MGR）接受遗留数据实用性培训。他们还将被介绍给NSF海洋沉积物采样（MARSSAM）设施和MARSSAM工作人员提供给NSF取芯PI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、最终选址、岩芯处理、多传感器岩芯记录仪数据收集和解释以及船上岩芯描述和管理的培训。在考察后讲习班上，高级导师将指导参加者解释岩心说明，将收集的岩心和初步物理性质数据与地层/沉积环境相结合。 该奖项反映了NSF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。
