Upgrade and Operation of a Marine-Atmospheric Sampling Facility at Tudor Hill, Bermuda

气溶胶和气体的大气输送和海气交换在许多元素的全球地球化学循环中起着重要作用。这些过程还对全球辐射收支施加重要控制，并影响主要人为污染物的浓度和分布。我们目前关于大气输送和海洋大气交换的许多知识来自于在大气采样站收集的时间序列数据，其中海洋站点是必不可少的组成部分。由于其在北大西洋西部的战略地理位置，百慕大一直是许多海洋大气研究的一个关键取样地点，而且它很可能在今后的实地研究中发挥重要作用。在这个项目中，百慕大生物研究站的研究小组将：(1)升级和维护百慕大都铎山最先进的大气采样站；（二）运行大气采样站，为其他研究人员主持的研究项目提供大气样本采集和分析仪器操作设施；(3)与其他调查人员合作和支持，持续收集和存储选定的核心气象数据和大气样本。该项目收集的时间序列数据和样本将为未来在百慕大地区进行的海洋大气研究项目提供基本背景，而采样设施的升级和维护将为这些项目提供所需的基本支持。

ABSTRACTOCE-0138352The atmospheric transport and air-sea exchange of aerosols and gases play major roles in the global geochemical cycles of many elements. These processes also exert significant controls on the global radiation budget and affect the concentrations and distributions of major anthropogenic pollutants. Much of our present knowledge of atmospheric transport and ocean- atmosphere exchange has come from time-series data collected at atmospheric sampling stations, of which oceanic sites are essential components. Bermuda has been a key sampling location for numerous studies of the marine atmosphere, owing to its strategic geographic location in the western North Atlantic, and it is likely to feature importantly in future field studies. In this project, the research team at the Bermuda Biological Station for Research will: (1) upgrade and maintain a state-of-the-art atmospheric sampling station at Tudor Hill, Bermuda; (2) operate this atmospheric sampling station to provide facilities for the collection of atmospheric samples and operation of analytical instrumentation in research programs led by other investigators; and (3) collect and store selected core meteorological data and atmospheric samples on a continuous basis, in collaboration with and in support of other investigators.The time-series data and samples collected in this program will provide the basic context for future marine-atmospheric research programs to be conducted in the Bermuda region, while the upgrade and maintenance of sampling facilities will provide the basic support needed for such programs.
