This project provides continuing support for the Tudor Hill Marine Atmospheric Observatory in Bermuda. The marine boundary layer, the lower level of the atmosphere over the oceans, plays important roles in the global cycles of many chemical elements and this observatory provides a unique facility for the ocean and atmospheric chemistry research communities. At present, many aspects of atmospheric composition, atmospheric transport, and atmosphere-ocean exchange remain poorly understood. This limits our ability to predict and mitigate the effects of anticipated future environmental change. Central to improving our understanding of these topics is the ability to observe and sample the marine boundary layer. In this regard, oceanic island observatories have played a crucial role. By virtue of its location in the western North Atlantic Ocean, Bermuda has been a key location for numerous field studies of the marine troposphere and is well equipped for such research, with the 23 meter high atmospheric sampling tower and site laboratories at Tudor Hill. Routine facility operations include the collection of continuous meteorological data and weekly bulk aerosol and rainwater samples, which are archived at the Bermuda Institute of Ocean Sciences and made freely available to the scientific community. Additionally, samples and data are collected for a variety of external research programs funded by NSF, NOAA, NASA and other agencies. This project is expected to make significant educational contributions at a number of levels, including undergraduate education opportunities through the NSF-funded Research Experience for Undergraduates (REU) program, and through other courses taught at the Bermuda Institute of Ocean Sciences.The continued operation and maintenance of THMAO site will facilitate research topics that are central to international research initiatives such as IGAC, SOLAS and GEOTRACES. The specific objectives of the project are to: 1) Operate and maintain the atmospheric sampling facility at Tudor Hill, Bermuda; 2) Continue collection of continuous meteorological data and weekly bulk-aerosol and rain samples, which will be archived at BIOS and made freely available to other researchers; and 3) Collect additional atmospheric samples and data for external investigators, and provide for the use of the facility by external investigators. The continued operation and maintenance of the Tudor Hill site facilitates research concerning the chemistry and physics of the marine troposphere and ocean-atmosphere exchange processes. In a regional context, the Tudor Hill facility will complement ongoing time-series research in the Sargasso Sea, including Hydrostation S and BATS.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

该项目为百慕大的Tudor Hill海洋大气天文台提供了持续的支持。海洋边界层是海洋上的大气层，在许多化学元素的全球周期中都起着重要作用，该天文台为海洋和大气化学研究社区提供了独特的设施。目前，大气组成，大气传输和大气 - 海洋交换的许多方面仍然了解不足。这限制了我们预测和减轻预期未来环境变化影响的能力。提高我们对这些主题的理解的核心是观察和采样海洋边界层的能力。在这方面，海洋岛观测者发挥了至关重要的作用。由于其位于北大西洋西部的位置，百慕大一直是海洋对流层众多现场研究的关键地点，并为此类研究提供了很好的装备，在Tudor Hill拥有23米高的大气采样塔和现场实验室。常规设施的操作包括收集连续的气象数据以及每周的散装气溶胶和雨水样品，这些样品在百慕大海洋科学研究院存档，并可以自由地提供给科学界。此外，还为由NSF，NOAA，NASA和其他机构资助的各种外部研究计划收集了样本和数据。预计该项目将在多个层面上做出重大的教育贡献，包括通过NSF资助的本科生（REU）计划以及通过在百慕大海洋科学研究所教授的其他课程的研究经验。该项目的具体目标是：1）在百慕大都铎山（Tudor Hill）运营和维护大气抽样设施； 2）继续收集连续的气象数据以及每周的散装型和雨水样本，这些样本将在BIOS存档，并免费提供给其他研究人员； 3）为外部调查人员收集其他大气样本和数据，并提供外部研究人员使用该设施。 Tudor Hill遗址的持续运行和维护促进了有关海洋对流层和海洋 - 大气交换过程的化学和物理学的研究。在区域背景下，都铎山的设施将补充萨尔加索海中正在进行的时间序列研究，包括液压S和BAT。该奖项反映了NSF的法定任务，并被认为是值得通过基金会的知识分子优点和更广泛的影响审查标准通过评估来获得支持的。
