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起来的热量和物质的通量，对于解决Ridge2000奋进号综合研究地点实施计划中提出的主要问题至关重要。该项目将获得两组互补的观测数据：从奋进号分段喷口场上升的流体质量、热量和盐的垂直通量以及轴向谷内流体质量的横向输送。通过在火山口周围建立适当的控制体，并使用自动驾驶车辆ABE，辅以精确导航的CTD观测和附近的流计系泊，测量火山口边界的温度、盐度和速度场，可以测量火山口的垂直通量。横向流体通量将通过密集的常规流计系泊和向上看的声学流剖面仪进行测量。

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.
