Measurement of the fluxes of heat and materials that tie geological forcing to biological response is central to addressing the major questions posed in the Ridge2000 Endeavour Integrated Studies Site implementation plan. This project will acquire two sets of complementary observations: the vertical fluxes of fluid mass, heat and salt rising from the Endeavour segment vent fields and the lateral transport of fluid mass within the axial valley. The vertical fluxes from the vent fields will be measured by establishing appropriate control volumes around them and using the autonomous vehicle ABE, complemented by precisely navigated CTD observations and a nearby current meter mooring, to measure the temperature, salinity and velocity fields on their boundaries. The lateral fluid flux will be measured with a dense array of conventional current meter moorings and up-looking acoustic current profilers.

测量将地质作用力与生物反应联系在一起的热量和物质通量，是解决海脊2000年奋进综合研究地点执行计划中提出的主要问题的核心。 该项目将获得两组互补的观测结果：奋进号段喷口区上升的流体、热和盐的垂直通量，以及轴向谷内流体的横向迁移。 将在喷口区周围建立适当的控制容积，并使用自主飞行器ABE测量喷口区的垂直通量，辅之以精确导航的CTD观测和附近的海流计系泊，以测量喷口区边界的温度、盐度和速度场。 横向流体通量将使用密集阵列的常规海流计系泊装置和上视声学海流剖面仪进行测量。
