目前的建议是针对收购 实际上是连续的，同时发生的地球化学-物理- 在赤道太平洋的一个站点（0，140 W）的光学数据， JGOFS计划的一部分。 目前，气象，电流， 和温度数据正在从位于 由PMEL/NOAA的Michael McPhaden博士提供。 麦克菲登医生 在这方面的努力将补充在该网站的测量 通过在4个深度放置多变量系泊系统（MVMS） 在这个系泊处上方120米以内。 收集的数据 MVMS单元将包括：电流，温度， 电导率、束流衰减系数、受激和 天然荧光，溶解氧，光合作用 有效辐射（PAR），光谱上升流辐射， 光谱下涌辐照度 衍生可变产品 从MVMS装置和PMEL电流计和温度 记录器将包括：分层，混合层深度， 混合时间尺度和电流剪切。 其他MVMS 产品将包括：光谱漫衰减 可以用来计算穿透力的光 太阳辐射的分量以及生物光学模型， 颗粒浓度，色素生物量，初级生产力 （使用几种方法），综合色素生物质和初级 生产，氧呼吸和利用， 氧气穿过海-气界面，平流和通量 颗粒和色素的混合物。 MVMS单位将提供 几乎连续的时间序列约6个月， 部署，从而补充和跨越计划的 JGOFS/NOAA船上研究。

The present proposal is directed toward the acquisition of virtually continuous, concurrent biogeochemical-physical- optical data at a site (0, 140W) in the equatorial Pacific as part of the JGOFS program. Presently, meteorological, current, and temperature data are being collected from a mooring at the site by Dr. Michael McPhaden of PMEL/NOAA. Dr. McPhaden's measurements at that site will be complemented in this effort by placing Multi-Variable Moored Systems (MVMS) at 4 depths within the upper 120m on this mooring. The data collected from the MVMS units will include: currents, temperature, conductivity, beam attenuation coefficient, stimulated and natural fluorescence, dissolved oxygen, photosynthetically available radiation (PAR), spectral upwelling radiance, and spectral downwelling irradiance. Derived variable products from the MVMS units and the PMEL current meters and temperature recorders will include: stratification, mixed layer depth, mixing time scales, and current shears. Additional MVMS products will include: the spectral diffuse attenuation of light which can be used for computation of the penetrative component of solar radiation as well as for bio-optical models, particle concentrations, pigment biomass, primary production (using several methods), integrated pigment biomass and primary production, oxygen respiration and utilization, the flux of oxygen across the air-sea interface, and the advection and flux of particles and pigments. The MVMS units would provide virtually continuous time series for about 6 months per deployment, thus complementing and spanning the planned JGOFS/NOAA shipboard studies.
