The ocean absorbs a large fraction of the atmospheric carbon dioxide generated by the burning of fossil fuels. Much of this uptake occurs in high latitude (polar) regions of the ocean. However, current monitoring capabilities in the polar ocean are limited. The Ocean Observatories Initiative (OOI) aims to address this need by providing 25 years of continuous physical and biogeochemical sensor data from autonomous platforms in the high latitude ocean. This CAREER project will improve understanding of the marine carbon cycle in the high latitude ocean using OOI data. The science team will use biogeochemical data collected by the OOI sensors to monitor long term changes in carbon cycling processes. In addition, this CAREER project includes educational activities to broaden participation in oceanographic research. The lead scientist will develop a new research seminar course to provide training and research opportunities for undergraduate students. A series of educational videos will be created to showcase the use and application of OOI data. The videos will be used in college level courses at three universities. This project will provide training opportunities for eight undergraduate students, two doctoral students, and one postdoctoral researcher.This CAREER project will utilize marine biogeochemical time series data from Ocean Observatories Initiative (OOI) locations in the subpolar North Atlantic and subarctic Northeast Pacific to evaluate the relative roles of biological, chemical, and physical processes driving the ocean’s carbon sink. The project seeks to improve the usability of OOI biogeochemical (BGC) sensor data and leverage these marine BGC time series data to determine changes in carbon cycling processes in the subpolar North Atlantic and subarctic Northeast Pacific Oceans. This research is key for predicting long term perturbations due to climate change and for understanding how changes in carbon cycling in these regions will influence carbon sequestration. The objectives of this project are to: 1) quantify the rates and drivers of carbon cycling and long-term carbon sequestration in the subpolar North Atlantic and subarctic Northeast Pacific Oceans and 2) determine the mechanistic controls on the ocean carbon sink due to inter-related biological, chemical, and physical processes over 10 years at each array site. The high temporal resolution BGC data collected by the arrays will improve understanding of the sampling resolution needed to capture key carbon cycling processes and test the hypothesis that short-time scale events during spring phytoplankton blooms and strong winter storms play a significant role in the overall annual carbon cycle. Education activities associated with this CAREER project include a series of educational videos about OOI and use of the data it provides that will be incorporated into undergraduate courses, a new research seminar course for undergraduates, and research opportunities for undergraduate and graduate students as well as a postdoctoral researcher.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.

海洋吸收了化石燃料燃烧产生的大部分大气二氧化碳，但海洋观测站目前的监测能力有限。倡议 (OOI) 旨在通过提供来自高纬度海洋自主平台 25 年的连续物理和生物地球化学传感器数据来满足这一需求。该职业项目将利用 OOI 增进对高纬度海洋海洋碳循环的了解。科学团队将利用 OOI 传感器收集的生物地球化学数据来监测碳循环过程的长期变化。此外，该职业项目还包括扩大海洋学研究参与范围的教育活动。首席科学家将开发一门新的研究研讨会课程。为本科生提供培训和研究机会，将制作一系列教育视频来展示 OOI 数据的使用和应用。这些视频将在三所大学的大学课程中使用。该项目将为八名本科生提供培训机会。学生，两名博士生，和一名博士后研究员。该职业项目将利用海洋观测倡议（OOI）北大西洋亚极地和东北太平洋亚北极地区的海洋生物地球化学时间序列数据来评估驱动海洋碳汇的生物、化学和物理过程的相对作用该项目旨在提高 OOI 生物地球化学 (BGC) 传感器数据的可用性，并利用这些海洋 BGC 时间序列数据来确定北大西洋和近极地碳循环过程的变化这项研究对于预测气候变化造成的长期扰动以及了解这些地区碳循环的变化将如何影响碳固存至关重要。该项目的目标是：1）量化碳固存的速率和驱动因素。北大西洋亚极地和东北太平洋亚北极的碳循环和长期碳封存；2）由于相互关联的生物、化学和物理过程，确定了对海洋碳汇的机械控制。每个阵列站点收集的高时间分辨率 BGC 数据将提高对捕获关键碳循环过程所需的采样分辨率的理解，并检验春季浮游植物大量繁殖和冬季强风暴期间发生的短时尺度事件的假设。与该职业项目相关的教育活动在整个年度碳循环中发挥着重要作用，包括一系列有关 OOI 及其提供的数据使用的教育视频，这些视频将纳入本科生课程、面向本科生的新研究研讨会课程和研究。机会面向本科生、研究生以及博士后研究员。该奖项反映了 NSF 的法定使命，并通过使用基金会的智力价值和更广泛的影响审查标准进行评估，被认为值得支持。
