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 transmissometers and of aggregates using Large Aggregate Profiling Systems (LAPS). LAPS profiling is proposed during the two transect cruises and the two times-series in EQPAC to contribute to the solution of the above problems. LAPS also has a 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.

在这个项目中，大小颗粒的分布 将在美国联合全球海洋通量研究中进行测量， 中赤道太平洋（EQPAC），以解决两个 EQPAC正在解决的五个问题，即： 问题一：物理强迫与 和上层海洋的地球化学循环 问题四：哪些过程负责运输 以及颗粒和溶解营养物的再生？ 这项工作旨在填补知识的空白， 小颗粒的高分辨率轮廓， 透射计和使用大骨料的骨料 分析系统（LAPS）。 LAPS分析建议在 EQPAC中的两个样带巡航和两个时间序列， 有助于解决上述问题。 LAPS也 具有透射计和CTD，可同时获得轮廓 光束衰减（与小颗粒成比例 浓度）、温度和盐度来比较颗粒 水结构的分布。
