In this project the distribution of large and small particles will be measured in the U.S. Joint Global Ocean Flux Studies in the Central Equatorial Pacific (EQPAC) to address two of the five problems being addressed in EQPAC, namely: Problem I: What is the relationship between physical forcing and upper ocean biogeochemical cycles? Problem IV: Which processes are responsible for the transport and regeneration of particulate and dissolved nutrients? The work is designed to fill that gap in knowledge by making high resolution profiles of small particles using transmissometer and CTD to obtain simultaneous profiles of beam attenuation (proportional to small particle concentration), temperature and salinity to compare particle distributions with water structure.

在该项目中，美国中赤道太平洋全球海洋通量联合研究 (EQPAC) 将测量大颗粒和小颗粒的分布，以解决 EQPAC 正在解决的五个问题中的两个，即： 问题一：物理强迫与上层海洋生物地球化学循环之间的关系是什么？ 问题四：哪些过程负责颗粒和溶解养分的运输和再生？ 这项工作旨在填补这一知识空白，通过使用透射计和 CTD 制作小颗粒的高分辨率剖面，以获得光束衰减（与小颗粒浓度成比例）、温度和盐度的同步剖面，以将颗粒分布与水结构进行比较。
