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

气溶胶和气体的大气传输和海气交换在全球许多元素的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产生重大控制，并影响主要人为污染物的浓度和分布。 我们目前关于大气迁移和海洋-大气交换的知识大部分来自大气采样站收集的时间序列数据，海洋采样站是其中的重要组成部分。 由于百慕大位于北大西洋西部的战略地理位置，它一直是许多海洋大气研究的一个重要取样地点，在今后的实地研究中，它很可能占有重要地位。在这一项目中，百慕大生物研究站的研究小组将：（1）更新和维持百慕大Tudor Hill的一个最先进的大气采样站;（2）操作这一大气采样站，为收集大气样本提供设施，并为其他调查人员领导的研究方案操作分析仪器;和（3）与其他研究人员合作并支持他们，持续收集和储存选定的核心气象数据和大气样本。该计划中收集的时间序列数据和样本将为百慕大地区未来的海洋-大气研究计划提供基本背景，而采样设施的升级和维护将为这些方案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.
