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 Fisher 这项研究的总体目标是量化管虫、相关自由生活细菌和相关动物群的生产力和生物量，并确定和量化单一热液喷口系统中管虫群落内外的营养途径。 实验设计将允许对这些具有通风时间变化的参数进行建模，并且这些数据将适合包含在通风场规模生产力的更大规模建模工作中。 该研究地点是胡安德富卡海岭奋进段的一部分，许多其他项目正在进行中，并与美国海脊项目的海底观测站部分一起规划。其他研究的宝贵输入和该项目的结果可以在理解山脊系统的地球化学、生物学和地质学变化的更大背景下进行解释。 ***
