备注

长期以来观测数据的不足严重制约着海洋生物地球化学过程的研究,随着技术发展,搭载物理、生物与化学多传感器的生物地球化学剖面浮标(BGC-Argo浮标)为海洋观测带来了重大改变:通过长期自动化剖面观测,可以覆盖从昼夜、季节到年际的连续时间尺度; 通过阵列式投放可以覆盖从次中尺度、中尺度、海盆到全球的连续空间尺度; 高垂向分辨率的观测数据可以同船载观测和遥感观测相互补充.海量的观测数据有助于各种海洋生物地球化学过程的研究,并进一步认识、理解与预测海洋生物地球化学循环、生物泵过程以及海洋生态系统.主要综述了BGC-Argo的发展背景、科学目标、主要应用以及目前在南海的应用进展.

Ocean biogeochemical research has been limited by insufficient observation data for a long time.With the development of technology,the biogeochemical Argo(BGC-Argo)floats bring evolutionary change to ocean observation,through equipping diverse physical,biological,and chemical sensors on Argo floats.Thanks to its capability of autonomous profiling observation in the open ocean,BGC-Argo floats cover continuous temporal scales(from diurnal,seasonal,to interannual).Through an array deployment,BGC-Argo floats would cover continuous spatial scales(from sub-meso,meso,basin,to global).With high vertical resolution,BGC-Argo floats not only supplement the data gap between ship-based and satellite-based platforms,but also provide large amounts of data that have contributed to various biogeochemical research,and further understanding,comprehension and prediction of ocean biogeochemical cycles,biological pumping and ecosystems.This paper reviews the backgrounds,scientific objectives,and application studies of BGC-Argo floats,and especially its application in the South China Sea.
