9633105 Fisher The overall goal of this study is to quantify the productivity and biomass of the tubeworms, associated free- living bacteria, and associated fauna, and to identify and quantify trophic pathways within and out of the tubeworm communities in a singel hydrothermal vent system. The experimental design will allow modeling of these parameters with temporal variability of venting, and the data will be suitable for inclusion in larger scale modeling efforts of vent field scale productivity. The study site is a portion of the Endeavour segment of the Juan de Fuca Ridge, where many other programs are underway and planned in conjunction with the seafloor observatory component of the US RIDGE program. Valuable input from other studies and the results from this project can be interpreted in the larger context of understanding the variability of the geochemistry, biology and geology of ridge systems. ***

9633105这项研究的总体目标是量化小管菌，相关的自由细菌和相关的动物的生产率和生物量，并识别和识别和量化单热热通风孔系统中的TubeWorm社区内外的营养途径。 实验设计将允许对这些参数进行通风的时间变化进行建模，并且数据将适合纳入通风范围尺度生产率的更大尺度建模工作。 研究地点是Juan de Fuca Ridge的努力领域的一部分，在那里正在进行许多其他计划，并与美国山脊计划的海底天文台组成部分一起计划。可以在理解山脊系统地球化学，生物学和地质的变异性的更大背景下解释其他研究的宝贵意见以及该项目的结果。 ***
