This award would provide a year of continuation funding for the Tudor Hill Marine Atmospheric Observatory in Bermuda. 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-m 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. 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 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 BIOS.

该奖项将为百慕大的都铎山海洋大气观测站提供一年的持续资金。海洋上空的低层大气在许多化学元素的全球循环中起着重要作用，这个天文台为海洋和大气化学研究界提供了一个独特的设施。目前，人们对大气成分、大气输送和大气-海洋交换的许多方面仍知之甚少。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，海洋岛屿观测站发挥了至关重要的作用。由于其位于北大西洋西部，百慕大一直是众多海洋对流层实地研究的关键地点，并且拥有23米高的大气采样塔和都铎山的现场实验室，为此类研究提供了良好的设备。常规设施操作包括收集连续气象数据和每周大量气溶胶和雨水样本，这些数据存档于百慕大海洋科学研究所，并免费提供给科学界。此外，样本和数据收集的各种外部研究项目由NSF， NOAA， NASA和其他机构资助。该项目的具体目标是：1)操作和维护百慕大Tudor Hill的大气采样设施；2)继续收集连续的气象数据和每周的气溶胶和雨水样本，这些数据将存档于BIOS，并免费提供给其他研究人员；3)为外部调查人员收集额外的大气样本和数据，并为外部调查人员使用该设施提供条件。都铎山站点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研究。在区域范围内，Tudor Hill设施将补充马尾藻海正在进行的时间序列研究，包括S站和BATS站。该项目预计将在多个层面上做出重大的教育贡献，包括通过nsf资助的本科生研究经验（REU）计划获得本科教育机会，以及通过BIOS教授的其他课程。
