Time-Series Particle Flux Measurements In The Sargasso Sea

9312826 DUSER本研究将在马尾藻海500m、1500m和3200m深度继续进行时间序列粒子通量测量，为期三年。3200米系列目前的使用年限超过15年。这是迄今为止同类系列中最长的一部。这项工作将与附近“S”站的水文时间序列和邻近地区越来越多的联合全球海洋观测系统时间序列测量(BAT)一起，继续提供关于公海物理、化学和生物变量的数据库。多年来，这一时间序列证明了深海存在时间变异性，揭示了从表层海洋中清除物质的过程的效率，并记录了这些过程对深海化学和生物的许多影响。将继续寻找继任者PI，同时维持该系列和所有相关分析工作，查明碳通量对深海的强迫作用，评估“生物泵”功效的十年尺度趋势，并监测人为成分向深海的运输。

9312826 DEUSER This study will continue time-series particle-flux measurements at depths of 500, 1500, and 3200 m in the Sargasso Sea for three years. The 3200-m series presently extends over 15 years. It is by far the longest series of its kind. Together with the hydrographic time series at nearby Station "S" and with the growing number of JGOFS time-series measurements (BATS) in the immediate vicinity this work will continue to provide a data base on physical, chemical and biological variables in the open ocean. Over the years this time series has demonstrated the existence of temporal variability in the deep ocean, revealed the efficiency of processes removing materials from the surface ocean, and documented many of the effects of those processes on the chemistry and biology of the deep ocean. A search for a successor PI will be continued along with maintaining the series and all associated analytical work as well as identifying the forcing functions of carbon flux to the deep ocean, assessing decade-scale trends in the efficacy of the "biological pump", and monitoring transport of anthropogenic components to the deep ocean.
