Biogeochemical-Argo (BGC-Argo) is a network of profiling floats carrying sensors that enable observation of as many as six essential biogeochemical and bio-optical variables: oxygen, nitrate, pH, chlorophyll a, suspended particles, and downwelling irradiance. This sensor network represents today's most promising strategy for collecting temporally and vertically resolved observations of biogeochemical properties throughout the ocean. All data are freely available within 24 hours of transmission. These data fill large gaps in ocean-observing systems and support three ambitions: gaining a better understanding of biogeochemical processes (e.g., the biological carbon pump and air–sea CO2 exchanges) and evaluating ongoing changes resulting from increasing anthropogenic pressure (e.g., acidification and deoxygenation); managing the ocean (e.g., improving the global carbon budget and developing sustainable fisheries); and carrying out exploration for potential discoveries. The BGC-Argo network has already delivered extensive high-quality global data sets that have resulted in unique scientific outcomes from regional to global scales. With the proposed expansion of BGC-Argo in the near future, this network has the potential to become a pivotal observation system that links satellite and ship-based observations in a transformative manner.

用生物地球化学观测仪观察全球海洋

Biogeochemical-Argo(BGC-Argo)是一个带有传感器的轮廓浮标网络,可以观察多达六个基本的生物地球化学和生物光学变量:氧气,硝酸盐,pH,叶绿素a,悬浮颗粒和向下辐射。该传感器网络代表了当今收集海洋中生物地球化学特性的时间和垂直分辨观测资料的最有前途的策略。所有数据在传输后24小时内均可免费获得。这些数据填补了海洋观测系统的巨大空白,并支持以下三个目标:对生物地球化学过程(例如生物碳泵和海气CO 2)有更好的了解交流)并评估由于人为压力增加(例如酸化和脱氧)而引起的持续变化;管理海洋(例如,改善全球碳预算和发展可持续渔业);并进行潜在发现的探索。BGC-Argo网络已经提供了广泛的高质量全球数据集,这些数据集产生了从地区到全球范围的独特科学成果。随着BGC-Argo计划在不久的将来进行扩展,该网络有可能成为枢纽性观测系统,以革命性的方式链接卫星和舰船观测。
