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.

南大洋碳和气候观测与建模（SOCCOM）项目旨在提高我们对南大洋在从大气中吸收人为碳和热量以及将营养物质从深渊重新供应到表面方面的关键作用的理解。一个观测组成部分，基于部署具有氧气，硝酸盐，pH值和生物光学传感器的剖面浮标，正在提供前所未有的大量新的海洋地球化学数据，提供从表面到2000米水深的南大洋全年视图，包括跟踪海洋酸化，脱氧和变暖过程。一项建模工作正在应用这些观测结果，增强我们对现代南大洋的理解，并减少对未来碳和营养循环以及气候预测的不确定性。要求将这一方案从6年延长到10年。这可能有助于阐明南大洋在气候中的作用，而这在较短的时间尺度内是不可能做到的，并可利用足够的浮标和多年数据进行区域比较，以阐明每个海盆可能发生的不同过程。该项目将通过已建立的数据网络、出版物、网站和社交媒体，以及通过面向教室、公众和决策者的积极外联计划，迅速向更广泛的社区传播数据和结果。第二个目标是培养新一代精通现场技术、数据校准、建模和向非科学家传播研究成果的多元化海洋科学家。第三个目标是完成新传感器技术和相关软件向行业合作伙伴的转移。由于南大洋是海洋中层、深层和底层沃茨与海洋表层（进而与大气层）相连的主要通道，它对海洋吸收人类活动产生的碳和热量以及从深海向海洋表层再补给营养物质有着深远的影响。这里提议的SOCCOM浮标计划延长四年，将允许检查南大洋对包括ENSO和南部环形模式在内的气候变率关键模式的反应。这也有助于开发和分析完全耦合的气候和地球系统模型，可以代表中尺度过程在南大洋，以及相应的模型，同化观测，以产生一个地球化学状态的估计。这个奖项反映了NSF的法定使命，并已被认为是值得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的支持。
