Despite its importance in regulating the climate and sustaining life on Earth, the ocean is a largely under sampledand unknown ecosystem. This ignorance is preventing us from accurately predicting how ocean biology andbiogeochemical cycles will respond to the ongoing climate warming.Observations are key to understanding. Satellite data have revealed previously unknown mechanisms, but arelimited because they can only detect surface processes and estimate a limited set of biogeochemical parameters.Ship measurements can overcome these limitations, but are constrained by extremely high costs and thusseverely limited in spatio-temporal coverage.A network of Bio-Argo floats will complement satellite and ship measurements and synergistically allow us tomonitor biogeochemical variables over sustained periods of time. For the first time, scientists will be able to exploit sustained observations to understand biogeochemical processes occurring in the deeper layers of thewater column. The first Bio-Argo floats are already fundamentally changing our understanding of ocean biologyand biogeochemistry (Bishop et al., 2002, 2004; Riser and Johnson, 2008; Johnson et al., 2010; Boss andBehrenfeld, 2010). This new understanding, in turn, will improve ocean biogeochemical models and long termpredictions of the feedbacks between ocean biogeochemical cycles and Earth Climate. Improved predictions willthen inform policies. As such, the requested assets will boost NERC's science on marine ecosystems, globalbiogeochemical cycles and Earth's climate predictions.The ability to sustain biogeochemical observations in the Atlantic ocean over time and space will expand thescope of the Atlantic Meridional Transect (AMT) cruise. In addition, the new data on vertically-resolvedbiogeochemical variables and rates will naturally feed into NERC supported biogeochemical modelling and dataassimilation activities. Finally, the novel data will significantly complement existing NCEO activities on ocean colourremote sensing by allowing us to extend the surface satellite data into three-dimensional observation fields.The Plymouth Marine Laboratory hosts recognized international experts in marine optics and its application toocean biology and biogeochemistry. This knowledge will be fundamental to assess the quality and interpret thebio-optical data collected by Bio-Argo floats and will be used to convert the optical proxies into biogeochemically relevant variables that will be distributed to the wider UK and international communities.

尽管海洋在调节气候和维持地球上的生命方面很重要，但它在很大程度上是一个缺乏采样和未知的生态系统。这种无知使我们无法准确预测海洋生物和生物地球化学循环将如何应对持续的气候变暖。观察是理解的关键。卫星数据揭示了以前未知的机制，但它们是有限的，因为它们只能探测表面过程和估计有限的生物地球化学参数集。船舶测量可以克服这些限制，但受到极高成本的限制，因此在时空覆盖方面受到严重限制。Bio-Argo浮标网络将补充卫星和船舶测量，并协同使我们能够在持续的一段时间内监测生物地球化学变量。科学家们将第一次能够利用持续的观测来了解发生在水柱深层的生物地球化学过程。首批Bio-Argo浮标已经从根本上改变了我们对海洋生物学和生物地球化学的理解（Bishop et al., 2002,2004； Riser和Johnson, 2008; Johnson et al., 2010； Boss和behrenfeld， 2010）。这一新的认识反过来将改进海洋生物地球化学模型和海洋生物地球化学循环与地球气候之间反馈的长期预测。改进后的预测将为政策提供信息。因此，所要求的资产将促进NERC在海洋生态系统、全球生物地球化学循环和地球气候预测方面的科学研究。维持大西洋生物地球化学观测随时间和空间变化的能力将扩大大西洋经向样带（AMT）巡航的范围。此外，关于垂直解析的生物地球化学变量和速率的新数据将自然地提供给NERC支持的生物地球化学建模和数据同化活动。最后，新数据将使我们能够将地面卫星数据扩展到三维观测领域，从而大大补充现有的NCEO海洋色彩遥感活动。普利茅斯海洋实验室拥有公认的海洋光学及其在海洋生物学和生物地球化学中的应用的国际专家。这些知识将是评估质量和解释Bio-Argo浮标收集的生物光学数据的基础，并将用于将光学代理转换为生物地球化学相关变量，这些变量将分发给更广泛的英国和国际社区。
