This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5).This new award will support the Hawaii Ocean Time-series (HOT) research program under the leadership Dr. Matthew Church, a stellar young scientist, for a 4 year period (August 2009-July 2013). The University of Hawaii will be the nexus for the entire HOT project, working with investigators at Oregon State University, Scripps Institution of Oceanography, Woods Hole Oceanographic Institute, and Montana State University to accomplish this important research on the changing biogeochemical, ecological and physical oceanographic processes being experienced in the changing climate of central gyres of the world's oceans. A project in NSF's portfolio on global climate and environmental change, this interdisciplinary research will include the exploration and documentation of the dynamics of the ocean's carbon cycle, the changing pH of the ocean, and the impacts on ecosystems of this "acidification." The project relies on monthly shipboard and near-continuous moored platform measurements to document variability in ocean properties and processes over time scales ranging from semi-diurnal to decadal.Since 1988, and under the leadership of Dr. David Karl, many teams of scientists have examined ocean ecosystem and climate variability at Station ALOHA (22°45'N, 158°W) in the North Pacific Subtropical Gyre (NPSG). Hallmarks of the earlier HOT research are an increased understanding of the sensitivity of biogeochemical cycling to large scale ocean-climate interactions, markedly improved quantification of the reservoirs and fluxes of ocean carbon and associated elements, identification of how changes to the North Pacific hydrological cycle influence ocean physics and biogeochemistry, and the creation of long-term data sets needed for assessing and predicting future climate perturbations on the ocean ecosystem. In preparing for this new award for the HOT research program, the investigators have worked with the broader oceanographic community to clarify and evolve the long-term objectives of the HOT program. There will be the explicit integration of the physical oceanographic components with the biogeochemical/ecosystem parts, and the overall effort will be centralized at the University of Hawaii while retaining the necessary multidisciplinary expertise for core elements of the research via sub-awards. This new award will allow the teams of scientists to pursue new research questions on ocean ecological and biogeochemical processes, while maintaining the high quality suite of measurements required for continued assessment of dynamics in ocean carbon and nutrient pools and fluxes, physical climate, plankton community structure, ecosystem productivity, particulate matter fluxes, and inherent optical properties. The new award will enhance the value of the program dataset for examining how low-frequency climate signals such as those associated with El Niño/Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO) influence the ecological habitat structure of the NPSG. Such efforts will continue to aid on-going biogeochemical and numerical ocean circulation models required for predicting how future habitat perturbations may influence ecosystem dynamics in the NPSG. Education, outreach, and training will play an important role in the HOT program activities. The cruises, the new data collected, and the historical context of the time-series provides a unique learning platform for high school, undergraduate, graduate and postdoctoral students and teachers from Hawaii and around the world. The monthly HOT cruises provide short-duration (4 day) opportunities for students and teachers to gain first-hand exposure to ocean and climate sciences. The new HOT award will support 2 graduate and 2 undergraduate student researchers, working with HOT scientists and gaining experience analyzing time series datasets. They will also develop valuable oceanographic sampling and laboratory skills as they pursue their own scientific projects. In addition, this HOT project and its people will help support the research of numerous other independent ocean scientists who can rely on the program's infrastructure (ship facilities, laboratories, equipment) to conduct their own independently funded research within a rich framework of understanding and environmental data collection. The data of the HOT project are readily accessible and freely available on the Internet. For example, the HOT surface carbon dioxie and pH records were recently included in the Fourth Assessment Report by the Inter-governmental Panel on Climate Change. With this new award, HOT will forge a stronger partnership with the Center for Microbial Oceanography: Research and Education (C-MORE), an NSF-funded Science and Technology Center at the University of Hawaii. C-MORE provides complementary infrastructure and scientific approaches for collaborative science, education and research training opportunities with HOT, including connections to programs designed to entrain women and under-represented ethic groups in the sciences. For example, HOT scientists will mentor undergraduate students of Native Hawaii ancestry through the CMORE Scholars program. In addition, HOT scientists and staff will participate in CMORE's Teacher-at Sea program that offers local area high school teachers opportunities to participate in the monthly HOT cruises.

该奖项是根据2009年的《美国复苏与再投资法》资助的（公共法111-5）。该新奖项将支持夏威夷海洋时间序列（HOT）研究计划，在领导力马修·教堂（Matthew Church）的领导下，一位出色的年轻科学家Matthew Dr.，为期4年（2009年8月 - 2013年8月 - 2013年8月）。夏威夷大学将成为整个HOT项目的联系，与俄勒冈州立大学的研究人员，Scripps海洋学，伍兹霍尔海洋学研究所和蒙大拿州立大学一起完成了这项关于不断变化的生物地球化学，生态和物理海洋学进程的重要研究，在世界中央大海洋中心环境中的变化中经历了这项经历。这项跨学科研究将在NSF的全球气候和环境变化方面的项目中进行，包括探索和记录海洋碳循环动态，海洋的变化以及对这种“酸化”的生态系统的影响。 The project relies on monthly shipboard and near-continuous moored platform measurements to document variability in ocean properties and processes over time scales ranging from semi-diurnal to decadal.Since 1988, and under the leadership of Dr. David Karl, many teams of scientists have examined ocean ecosystem and climate variability at Station ALOHA (22°45'N, 158°W) in the North Pacific Subtropical Gyre （NPSG）。较早的热门研究的标志是对生物地球化学对大规模海洋气候相互作用的敏感性的越来越多，明显改善了对海洋碳的储层和通量的量化以及相关元素的量化，并确定对北太平洋氢循环的变化如何影响海洋循环的变化，并评估了对长期数据的范围，并创建了生物的创建，并创建了Biogeemistion和Biogeecomision，以及生物的创建，以及范围的创建。生态系统。在为热门研究计划的新奖项做准备时，研究人员与更广泛的海洋学社区合作，澄清和发展了热门计划的长期目标。物理海洋成分将与生物地球化学/生态系统零件明确整合，整体努力将集中在夏威夷大学，同时通过副标题保留研究研究核心元素的必要多学科专业知识。这个新奖项将使科学家团队能够在海洋生态和生物地球化学过程中提出新的研究问题，同时维持继续评估海洋碳和属性池和属性池，物理气候，Plankton社区结构，生态系统生产力，颗粒物质磁通和遗传性特性所需的高质量测量套件。新奖项将提高计划数据集对研究低频气候信号（例如与ElNiño/Southern振荡相关的气候信号）和太平洋十年际振荡（PDO）影响的价值。这样的努力将继续帮助正在进行的生物地球化学和数值海洋循环模型，以预测未来的栖息地扰动如何影响NPSG的生态系统动态。教育，外展和培训新的热门奖将在热门计划活动中发挥重要作用。巡游，收集的新数据以及时间序列的历史背景为高中，本科，研究生和博士后学生以及来自夏威夷及世界各地的老师提供了独特的学习平台。每月的热水巡游为学生和老师提供了短期（4天）的机会，可以亲身接触海洋和气候科学。新的热门奖将支持2名研究生和2名本科生研究人员，与热门科学家合作，并获得经验分析时间序列数据集。他们还将在追求自己的科学项目时开发出宝贵的海洋学抽样和实验室技能。此外，这个热门项目及其人民将有助于支持许多其他独立的海洋科学家的研究，他们可以依靠该计划的基础设施（船舶设施，实验室，设备）来进行自己独立资助的研究，这是在理解和环境数据收集的丰富框架内进行的。热门项目的数据很容易访问，并且可以在Internet上免费获得。例如，最近由政府间气候变化小组纳入了第四次评估报告中，热表面碳二氧化碳和pH记录。有了这个新奖项，HOT将与微生物海洋学中心建立更牢固的伙伴关系：研究与教育（C-More），夏威夷大学NSF资助的科学技术中心。 C-More为合作科学，教育和研究培训机会提供了完整的基础设施和科学方法，其中包括与科学中旨在进入女性和代表性不足的伦理群体的计划的联系。例如，热门科学家将通过CMore Scholars计划指导夏威夷本地血统的本科生。此外，热门的科学家和工作人员将参加Cmore的Sea At At At At At At At At At At At At At At Ath Program，该计划为当地高中教师提供了参加每月热门巡游的机会。
