This award is funded under the American Recovery and Reinvestment Act of 2009 (Public Law 111-5). The ability to document and understand long-term trends in ocean climate and ecology, including the role of human activities on the biosphere, depends on an adequate knowledge of natural interdecadal fluctuations. The proposed research will document changes in benthic ecosystems in McMurdo Sound over the last four decades, i.e., since the beginning of quantitative studies of population and community organization in this region. The investigators will retrieve, analyze, and archive historical data of benthic assemblages in both hard and soft substrata, and continue work on several time series projects begun in the mid-1960s and early 1970s. The investigators will focus on the succession of marine invertebrate communities that have settled and survived on a variety of artificial substrates placed on the sea floor from the late 1960s to 1989. The substrates harbor several decades of information on patterns of settlement, growth, survival, longevity, overgrowth and other biological interactions and processes. The original researchers will relocate and permanently mark (with GPS) historical sampling sites; recover data from as much of the historical work as possible; provide meta-data to insure that past data are understood and sites can be properly resampled; and make all data available to the general science community in a permanent database housed at SCAR-MarBIN. The proposed work will be closely coordinated with an international macroecology program in the Ross Sea, represented by collaborator Simon Thrush (Latitudinal Gradient Project). In addition to reporting results in peer-reviewed publications and providing research support and opportunities for at least two graduate students, the investigators also will involve undergraduate and high school interns in the project, and participate in teacher education programs. The investigators will continue ongoing collaborations with K-12 outreach and college programs that focus on ocean science, and develop a new, broader public outreach effort with the Birch Aquarium at Scripps Institution of Oceanography.

该奖项是根据2009年《美国复苏与再投资法》（公法111-5）资助的。记录和理解海洋气候和生态学长期趋势的能力，包括人类活动在生物圈上的作用，取决于对自然跨际波动的足够了解。拟议的研究将记录过去四十年中McMurdo Sound底栖生态系统的变化，即自该地区人口和社区组织的定量研究开始。调查人员将在硬和软子基质中检索，分析和存档底栖组合的历史数据，并继续从1960年代中期和1970年代初开始进行几个时间序列项目。调查人员将重点关注从1960年代后期到1989年在海底的各种人工基质上定居并幸存下来并幸存下来的海洋无脊椎动物社区的继任。寿命，过度生长和其他生物学相互作用和过程。最初的研究人员将搬迁并永久标记（GPS）历史抽样场所；从尽可能多的历史工作中恢复数据；提供元数据以确保了解过去的数据并可以正确采样；并在Scar-Marbin的永久数据库中向通用科学界提供所有数据。拟议的工作将与由合作者西蒙·鹅口疮（Simon Thrush）（纬度梯度项目）代表的罗斯海的国际宏观生态学计划密切协调。除了报告经过同行评审的出版物的结果以及为至少两名研究生提供研究支持和机会外，研究人员还将参与该项目的本科和高中实习生，并参与教师教育计划。调查人员将继续与K-12外展和大学课程进行持续的合作，该计划专注于海洋科学，并与Scripps海洋学研究所的Birch Aquarium开发了新的，更广泛的公共外展工作。
