High Resolution Determination of Carbon and Nitrogen fluxes from the Euphotic Zone at the JGOFS Bermuda Atlantic Time- Series MULTITRAP

用高分辨率时间序列研究颗粒通量 一个新的时间序列MULTITRAP，作为百慕大美国JGOFS的一部分 研究计划将实施。 这个陷阱的发展 作为美国JGOFS计划的一部分， 代表了获取非常高分辨率时间序列的努力 地表（300米）颗粒向下通量样本 沃茨。 该技术代表了一个组合的证明， Honjo时间序列旋转器机制和MULTITRAP多次波 VERTEX中使用的收集器PIT（粒子拦截器阱） （垂直转移和交换）、RACER（南极研究 生态系统速率），ADIOS（亚洲粉尘输入海洋系统）， 和NABE（JGOFS北大西洋水华实验）计划， 该系统目前在百慕大的联合全球海洋观测系统时间序列台站使用 (BATS、百慕大大西洋时间系列）和夏威夷（HOTS、夏威夷 海洋时间序列）。 这项新技术是为了解决 早期设计中固有的缺点，并且已经被 现场测试成功。 该项目将部署此陷阱， 一项研究旨在确定发生的变化的规模 在总质量、碳和氮的向下通量中， 与地表生产力的联系，以及两者的时间变化 出口产量和f比率。

A high resolution time-series study of particulate fluxes using a new time-series MULTITRAP as part of the Bermuda U.S. JGOFS research program will be implemented. Development of this trap was funded through the NSF as part of the U.S. JGOFS program and represents an effort to acquire very high resolution time-series samples of the downward flux of particles in surface (300m) waters. The technology represents a combination of the proven Honjo time-series rotator mechanism and the MULTITRAP multiple collector PIT (Particle Interceptor Trap) used in the VERTEX (Vertical Transfer and Exchange), RACER (Research on Antarctic Ecosystem Rates), ADIOS (Asian Dust Input to the Oceanic System), and NABE (JGOFS North Atlantic Bloom Experiment) Programs, and which is now used at the JGOFS time-series stations in Bermuda (BATS, Bermuda Atlantic Time-Series) and Hawaii (HOTS, Hawaii Ocean Time-Series). The new technology was developed to address shortcomings inherent in earlier designs, and has been successfully field tested. The project will deploy this trap in a study aimed at determining the scales of variability occurring in the downward flux of total mass, carbon and nitrogen, their links to surface productivity, and the temporal changes in both export production and f ratio.
