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.

海洋吸收了大部分大气二氧化碳，燃烧化石燃料产生。这种吸收大部分发生在海洋的高纬度地区。但是，极地海洋中当前的监测功能受到限制。海洋天文台倡议（OOI）旨在通过从高纬度海洋的自主平台提供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。这个职业项目将使用OOI数据来提高高纬度海洋中海洋碳循环的了解。科学团队将使用OOI传感器收集的生物地球化学数据来监视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的教育活动。首席科学家将开发一门新的研究SEMIAR课程，为本科生提供培训和研究机会。将创建一系列教育视频来展示OOI数据的使用和应用。这些视频将用于三所大学的大学级课程。该项目将为八名本科生，两名博士生和一名博士后研究员提供培训机会。本职业项目将利用海洋观测站的海洋生物地球化学时间序列数据（OOI）位置（OOI）位置（OOI）位于北大西洋和亚北极北部太平洋的该项目。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亚北极亚山极太平洋的碳循环过程的变化。这项研究是预测由于气候变化而导致的长期扰动的关键，以及了解这些区域中碳循环的变化将如何影响碳封存。该项目的目标是：1）量化北大西洋和亚北极亚北部和亚亚北太平洋的碳循环的速率和驱动因素和长期碳固相，2）确定由于相关的生物学，化学物质，化学物质和物理过程，在每个阵列阵列相关的物理过程中，海洋碳汇的机械控制。阵列收集的高临时分辨率BGC数据将提高人们对捕获关键碳循环过程所需的采样分辨率的了解，并检验以下假设：春季浮游植物血液中短期规模的事件和强烈的冬季风暴在整体年度碳循环中起着重要作用。与该职业项目相关的教育活动包括一系列有关OOI的教育视频以及使用其提供的数据，这些视频将被纳入本科课程中，这是一门新的研究课程，针对本科生的新研究课程以及本科生和研究生的研究机会，以及研究生以及博士生研究人员的著名奖项，这反映了NSF的众多奖项，并遍布了NSF的众多奖励，并在众多的范围内得到了良好的支持。 标准。
