The Southern Ocean Carbon and Climate Observations and Modeling (SOCCOM) project seeks to increase our understanding of the crucial role of the Southern Ocean in taking up anthropogenic carbon and heat from the atmosphere, and resupplying nutrients from the abyss to the surface. An observational component, based on deployment of profiling floats with oxygen, nitrate, pH and bio-optical sensors, is supplying unprecedented amounts of new biogeochemical data that provide a year-round view of the Southern Ocean from the surface to 2000 meters water depth, including tracking ocean acidification, deoxygenation, and warming processes. A modeling effort is applying these observations and enhancing our understanding of the modern Southern Ocean, and reducing uncertainty in projections of future carbon and nutrient cycles and climate. An extension of this program from six to ten years is requested. This may allow illumination of the Southern Ocean's role in climate that was not possible with a shorter time scale and allows regional comparisons with sufficient floats and years of data to elucidate the different processes that may operate in each basin. The project will communicate data and results quickly to the wider community through established data networks, publications, websites, and social media, as well as through an active outreach program to classrooms, the general public, and policymakers. A second goal is to train a new generation of diverse ocean scientists versed in field techniques,data calibration, modeling, and communication of research to non-scientists. A third goal completes the transfer of new sensor technology and related software to industry partners. Because the Southern Ocean serves as the primary gateway through which the intermediate, deep, and bottom waters of the ocean connect with the surface ocean (and thus the atmosphere), it has a profound influence on the oceanic uptake of anthropogenic carbon and heat as well as nutrient resupply from the abyss to the surface. The four year extension of the SOCCOM float program proposed here will allow examination of the Southern Ocean's response to critical modes of climate variability including ENSO and the Southern Annular Mode. This also contributes to the development and analysis of fully coupled climate and earth system models that can represent mesoscale processes in the Southern Ocean, as well as corresponding models that assimilate observations to produce a biogeochemical state estimate.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.

南部海洋碳和气候观测和建模（SOCCOM）项目旨在提高我们对南大洋在吸收人为碳和大气中热量的关键作用的理解，并从深渊到表面重新养成营养。基于用氧气，硝酸盐，pH和生物光光的传感器部署浮雕的观察成分，它提供了前所未有的新生物地球化学数据，这些数据提供了从地表到2000米的南方海洋的全年视图，到2000米的水深度，包括跟踪海洋酸化，脱氧化和暖氧化和温暖的过程。建模工作是应用这些观察结果，并增强我们对现代南大洋的理解，并减少未来碳和营养周期和气候的投影不确定性。要求将该计划从六年延长到十年。这可以允许在较短的时间范围内照明南洋在气候中的作用，并且可以与足够的浮子和多年数据进行区域比较，以阐明每个盆地中可能运行的不同过程。该项目将通过已建立的数据网络，出版物，网站和社交媒体以及通过向教室，公众和政策制定者进行积极的外展计划，将数据和结果迅速传达给更广泛的社区。第二个目标是培训新一代的各种海洋科学家，精通现场技术，数据校准，建模以及向非科学家进行研究的交流。第三个目标将新的传感器技术和相关软件转移给行业合作伙伴。由于南大洋是主要的门户，海洋的中间水域与地面海洋（以及大气层）相连，因此它对人为碳和热量的海洋吸收产生了深远的影响，以及从深渊到表面的营养补给。此处提出的SOCCOM浮点计划的四年延长将允许检查南大洋对气候变化关键模式的反应，包括ENSO和Southern Annular模式。这也有助于对完全耦合的气候和地球系统模型的开发和分析，这些模型可以代表南部海洋中的中尺度过程，以及相应的模型，这些模型吸收了观察以产生生物地球化学状态估计。这奖反映了NSF的立法任务，并被认为是通过基金会的智力评估和广泛的评估来评估的，并值得通过评估来进行评估。
