Primary Production and Nutritional Interaction in Vestimentiferan Aggregations on the Juan de Fuca Ridge

小行星9633105 本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。 实验设计将允许模拟这些参数的时间变化的通风，和数据将适合列入更大规模的模拟工作的通风场规模的生产力。 该研究地点是胡安·德富卡海脊奋进段的一部分，许多其他项目正在进行中，并计划与美国海脊计划的海底观测部分一起进行。其他研究的宝贵投入和本项目的成果可在理解洋脊系统的地球化学、生物学和地质学的变异性这一更大范围内加以解释。 ***

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. ***
