This project constitutes a portion of a large multi- investigator study examining the role of the entire heterotrophic community, from bacteria to large gelatinous zooplankton, in the recycling of primary production and its transport to depth in the oligotrophic Sargasso Sea. The objectives of this specific project are to quantify the biomass and consumption rates of the microzooplankton organisms in the size range of 20-200 um. A variety of methodologies will be employed. Profiling of the resident populations will be made several times a day throughout the cruise. Different types of grazing experiments will be conducted in collaboration with other researchers on the various prey and predator groups. The project involves two major cruises to station S off Bermuda which constitutes the Atlantic time-series site for the JGOFS initiative. The cruises are scheduled for August 1989 and April 1990 to coincide with productivity minima and maxima, respectively. The systematic approach of this group project to describe and quantify the flux of primary production through the epipelagic food-web will provide critical data on how the composition of the zooplankton community affects the flux rate of organic material from the euphotic zone.

该项目构成了一项大型多研究者研究的一部分，该研究研究了从细菌到大凝胶浮游生物的整个异养群落的作用，在初级生产的回收及其在少亲营养的sargasso海中的深度中的运输中。该特定项目的目标是量化微Zooplankton生物体的生物量和消耗率在20-200 um的范围内。将采用多种方法。在整个巡游中，将每天进行几次居民人口的分析。不同类型的放牧实验将与其他有关各种猎物和捕食者组的研究人员合作进行。该项目涉及两次大型巡游到百慕大旁的车站，这构成了JGOFS倡议的大西洋时间序列地点。巡游定于1989年8月和1990年4月，分别与生产力Minima和Maxima一致。该小组项目的系统方法描述和量化了通过表皮食品-WEB的初级生产的通量，将提供有关浮游动物群体组成如何影响兴巴区有机材料的通量速率的关键数据。
