The marine troposphere plays important roles in the global geochemical cycles of many elements, in the global radiation budget, and in the global distribution of organic compounds, nutrients, microbes, and pollutants. Our ability to sample this space between the atmosphere and the sea is central to improving our understanding of this dynamic zone. By virtues of its location in the western North Atlantic Ocean, Bermuda has been a key location for numerous field studies on the marine troposphere.With support through this grant, researchers at the Bermuda institute of Ocean Sciences (BIOS) will continue to maintain and operate a state-of-the-art Tudor Hill facility for three more years (September, 2011 through August, 2014). Operations will include the collection of continuous meteorological data and weekly bulk aerosol samples and rainwater samples. These data and samples will be archived at BIOS and made freely available to the scientific community, as well as the collection of samples and data for a variety of external research projects funded variously by NSF, NOAA, NASA, and other agencies. Modest user fees will be requested for the collection of samples or data in addition to those specified above or for other research use of the facility. Anticipated net revenue from these user fees (ca. $10,000 per year) will be used to defray costs of site maintenance, equipment replacement, and additional technician support.Broader Impacts: In general terms, the continued operation of the Tudor Hill facility will facilitate and augment research into the physics and chemistry of the lower marine troposphere and ocean-atmosphere exchange processes in the North Atlantic Ocean Basin -- topics that are of central importance to international research initiatives such as GEOTRACES, COLAS, and IGAC. Regionally, this facility will complement other ongoing time-series research in the Sargasso Sea, including the Bermuda Atlantic Time Series (BATS), Hydrostation S, and the Ocean Flux Program (OFP). As in the past, data and samples will be made available to support graduate student research as well as undergraduate educational activities and research.

海洋对流层在许多元素的全球地球化学循环、全球辐射收支以及有机化合物、营养物、微生物和污染物的全球分布中起着重要作用。 我们对大气和海洋之间的空间进行采样的能力对于提高我们对这个动态区域的理解至关重要。 凭借其位于北大西洋西部的地理位置，百慕大一直是海洋对流层众多实地研究的关键地点。在这笔赠款的支持下，百慕大海洋科学研究所（BIOS）的研究人员将继续维持和运营最先进的都铎山设施三年（2011年9月至2014年8月）。 业务将包括收集连续的气象数据和每周的大量气溶胶样本和雨水样本。 这些数据和样本将在BIOS存档，并免费提供给科学界，以及由NSF，NOAA，NASA和其他机构资助的各种外部研究项目的样本和数据收集。 除了上述规定的样品或数据收集或设施的其他研究用途外，还将要求适度的用户费用。 预计这些用户费用的净收入（约为100美元）。每年10，000美元）将用于支付场地维护、设备更换和额外技术支持的费用。一般来说，Tudor Hill设施的继续运行将促进和加强对北大西洋盆地低海洋对流层和海洋-大气交换过程的物理和化学研究，对国际研究计划至关重要的主题，如GEOTRACES，COLAS和IGAC。 在区域一级，该设施将补充正在马尾藻海进行的其他时间序列研究，包括百慕大大西洋时间序列、S水文站和海洋通量方案。 与过去一样，将提供数据和样本，以支持研究生研究以及本科生教育活动和研究。
