This effort will establish a time - series hydrographic station in the central North Pacific Ocean approximately 100km north of the island of Oahu as part of the Global Ocean Flux Study (GOFS) program. This deep water oceanographic station will comprise a Pacific Ocean analogue to Station S (Panulirus Station) located in the North Atlantic Ocean near Bermuda. Monthly visits will be made to this station over an initial five-year period to begin a comprehensive study of the distribution, production and flux of biogenic particulate material in the obligotrophic ocean. The scientific objectives are: (1) to observe and interpret the seasonal and interannual variability in the biology and chemistry of the mixed layer and the euphotic zone, (2) to observe and interpret the seasonal and interannual variability in the rates of particle flux and apparent rates of particle remineralization over the entire water column and (3) to understand the interrelationships between the processes mentioned in (1) and (2) above and the physical characteristics of the water column. Water column physical characteristics will be analyzed as part of the World Ocean Circulation Experiment (WOCE) during joint GOFS-WOCE cruises. The collective data obtained at the Hawaii time series station will also be used to support GOFS level-2 and level-3 studies on biogeochemical fluxes and ocean circulation and will contribute to the Hawaiian Ocean Experiment (HOE), a co-ordinated interdisciplinary study of the Hawaiian Exclusive Economic Zone (EEZ).

这项工作将在瓦胡岛以北约100公里的北太平洋中部建立一个时间序列水文测量站，作为全球海洋通量研究（GOFS）计划的一部分。这个深水海洋学站将包括一个太平洋模拟站S （Panulirus站），该站位于北大西洋百慕大附近。在最初的五年期间，将每月对该站进行访问，以开始对专营养性海洋中生物颗粒物质的分布、生产和通量进行全面研究。科学目标是：(1)观测和解释混合层和透光带生物化学的季节和年际变化；(2)观察和解释整个水柱上颗粒通量率和颗粒再矿化表观率的季节和年际变化；(3)了解上述(1)和(2)中提到的过程与水柱物理特征之间的相互关系。在GOFS-WOCE联合巡航期间，将分析水柱物理特性，作为世界海洋环流实验（WOCE）的一部分。在夏威夷时间序列站获得的集体数据还将用于支持全球环境观测系统关于生物地球化学通量和海洋环流的二级和三级研究，并将有助于夏威夷海洋实验，这是一项关于夏威夷专属经济区的协调的跨学科研究。
