Collaborative Research: Fluxes of Heat and Salt from Endeavour Segment Vent Fields: Discrete Measurements as a Test of the Sea Breeze "Flux Meter" Hypothesis

测量将地质强迫与生物反应联系在一起的热通量和物质通量，是解决2000年奋进综合研究场地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：奋进段喷口区域上升的流体质量、热量和盐分的垂直通量和轴向山谷内流体质量的横向输送。将通过在喷口周围建立适当的控制体并使用自动驾驶车辆ABE，辅之以精确导航的CTD观测和附近的海流计系泊来测量喷口区域的垂直通量，以测量其边界上的温度、盐度和速度场。横向流体通量将使用密集的常规海流计系泊装置和向上查看的声学海流剖面仪进行测量。

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.
