项目摘要

The ocean provides critical services to life on the planet, absorbing 93% of the heat caused by humans as well as a quarter of human carbon dioxide (CO2) emissions each year. However, rising ocean temperatures and CO2 levels also change the marine environment: pH and oxygen levels fall, ocean currents change, and nutrient fluxes and concentrations are shifting, all with effects on ecosystems and the cycles of oxygen, nitrogen, and carbon throughout the ocean and atmosphere. Until recently, observing these biogeochemical (BGC) changes across remote ocean areas with seasonal to interannual resolution has been impractical due to the prohibitive costs associated with large-scale ship operations. Now robotic profiling floats have been developed that are equipped with chemical and biological sensors, and which can operate independently for years. These robotic systems provide us the ability to observe changing ocean chemistry and biology in real time. This proposal will provide the funds to operate for five years an array of 500 such profiling floats that are distributed across the global ocean. The Global Ocean Biogeochemistry (GO-BGC) Array was funded through the NSF Mid-scale Research Infrastructure-2 program to deploy 500 biogeochemical (BGC) profiling floats around the globe. Each float will be equipped with a suite of chemical and biological sensors for oxygen, nitrate, pH, chlorophyll fluorescence, optical backscatter, and, in most cases, irradiance. The unprecedented real-time data stream from the GO-BGC Array will enable observation of ocean biogeochemical changes with seasonal to interannual resolution through the upper 2 km of the ocean, driving a transformative shift in scientific and public understanding of marine biogeochemical cycling and ocean health at the global scale. However, the MSRI-2 project does not provide funds to operate the array. Operational costs are centered on the expenses needed to transmit the large data stream from floats through the Iridium satellite communication system and the expenses to operate a data system that quality controls the incoming measurements and distributes the resulting, science quality data in real time. These data are then available without restriction. This proposal will provide the needed costs to transmit data from the GO-BGC array. It will support the quality control of float data streams to ensure that a high quality, science-ready data set is easily available to the community.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.

海洋为地球上的生命提供关键服务，吸收了人类引起的93％的热量以及每年人类四分之一的二氧化碳（CO2）排放。然而，海洋温度和二氧化碳水平的上升也改变了海洋环境：pH和氧气水平下降，洋流变化，养分通量和浓度正在发生变化，所有这些都会对生态系统以及氧气，氮气和碳的周期产生影响。直到最近，由于与大规模船舶运营相关的过高成本，观察到偏远海洋地区的这些生物地球化学（BGC）变化一直是不切实际的。现在，已经开发了配备化学和生物传感器的机器人分析浮子，并且可以独立运行多年。这些机器人系统使我们能够实时观察海洋化学和生物学的变化。该提案将为运营五年的资金提供500种此类分析浮子的阵列，这些浮子分布在全球海洋上。全球海洋生物地球化学（GO-BGC）阵列是通过NSF中尺度研究基础设施2计划资助的，以部署500个生物地球化学（BGC）分析在全球范围内漂浮。每个浮子将配备一套用于氧，硝酸盐，pH，叶绿素荧光，光学反向散射的化学和生物传感器，在大多数情况下是辐照度。来自GO-BGC阵列的前所未有的实时数据流将使海洋生物地球化学变化通过季节性到跨年级的海洋通过海洋上部2 km，从而在全球规模上对海洋生物地球化学循环和海洋健康的科学和公众了解。但是，MSRI-2项目没有提供用于操作数组的资金。运营成本集中在通过虹膜卫星通信系统从浮子传输大型数据流所需的费用以及操作数据系统的费用，该数据系统质量可以控制传入的测量结果并实时分发最终的科学质量数据。这些数据将无限制地提供。该建议将提供从GO-BGC阵列传输数据的所需费用。它将支持Float数据流的质量控制，以确保社区容易获得高质量，科学准备就绪的数据集。该奖项反映了NSF的法定任务，并使用基金会的知识分子优点和更广泛的影响评估审查标准，认为值得通过评估来获得支持。
