In order to meet its objectives, the Joint Global Ocean Flux Study must operate in both spatially intensive and spatially extensive modes (JGOFS, 1990), that is, in process studies at specific sites and in ocean surveys. This project is for the collection and processing of data on optics and pigment distributions in the survey mode, and combines the efforts of JGOFS and the World Ocean Circulation Experiment (WOCE) Hydrographic Program (WHP). The researchers will operate a bio- optical profiler to collect data on the biological and optical properties of the upper water column. The measurements to be made include spectral irradiance (upwelling and downwelling), broad-band visible irradiance (PAR), fluorescence, and beam transmission. This study represents the first undertaking of a systematic and consistent data collection on the oceans pigment and optical properties, and should be invaluable in improving algorithms for satellite imaging of ocean pigments and in estimating primary production. The data collected under this program will be provided to the oceanographic community in particular to JGOFS and WOCE Investigators in a timely fashion for analysis.

为了实现其目标，全球海洋通量联合研究必须在空间密集和空间广泛两种模式下进行（联合海洋研究基金，1990年），即在特定场址进行过程研究和进行海洋调查。本项目结合JGOFS和世界海洋环流实验（WOCE）水文测量计划（WHP）的努力，对调查模式下的光学和色素分布数据进行收集和处理。研究人员将使用生物光学剖面仪来收集上层水柱的生物和光学特性数据。要进行的测量包括光谱辐照度（上升流和下升流）、宽带可见辐照度（PAR）、荧光和光束透射。这项研究是第一次对海洋色素和光学特性进行系统和一致的数据收集，在改进海洋色素卫星成像算法和估计初级产量方面应该是非常宝贵的。根据本方案收集的数据将及时提供给海洋学界，特别是提供给JGOFS和WOCE调查员进行分析。
