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

该项目为百慕大的Tudor Hill海洋大气观测站提供持续支助。海洋边界层是海洋上空大气的低层，在许多化学元素的全球循环中起着重要作用，该观测站为海洋和大气化学研究界提供了一个独特的设施。目前，对大气成分、大气输送和大气-海洋交换的许多方面仍然知之甚少。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。百慕大由于地处北大西洋西部，一直是许多海洋对流层实地研究的关键地点，并拥有进行此类研究的良好设备，在Tudor Hill有23米高的大气取样塔和现场实验室。设施的日常运作包括收集连续的气象数据和每周的大量气溶胶和雨水样本，这些数据在百慕大海洋科学研究所存档，并免费提供给科学界。此外，还为NSF、NOAA、NASA和其他机构资助的各种外部研究项目收集样本和数据。该项目预计将在多个层面上做出重大的教育贡献，包括通过国家科学基金会资助的本科生研究经验（REU）计划提供本科生教育机会，以及通过百慕大海洋科学研究所教授的其他课程，THMAO网站的持续运营和维护将促进国际研究计划（如IGAC，SOLAS和GEOTRACES）的核心研究课题。该项目的具体目标是：1）运营和维护百慕大Tudor Hill的大气采样设施; 2）继续收集连续气象数据以及每周大量气溶胶和降雨样本，这些数据将在BIOS中存档并免费提供给其他研究人员;为外部调查人员收集更多的大气样本和数据，并为外部调查人员使用该设施提供便利。Tudor Hill站点的持续运行和维护有助于研究海洋对流层的化学和物理以及海洋-大气交换过程。在区域范围内，都铎山设施将补充正在进行的时间序列研究在马尾藻海，包括水电站S和BATS。这一奖项反映了NSF的法定使命，并已被认为是值得通过评估使用基金会的智力价值和更广泛的影响审查标准的支持。

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.
