Experimental Studies of Hydrothermal Plume Dynamics

该项目将进行热液羽流动力学的实验室实验。重点将放在中尺度气流上，其中旋转和地转调整是重要的。第一个实验将检验旋转对羽流上升高度的影响。第二部分将研究环境流动对羽流涡产生的影响。第三个将研究旋转对有限体积浮力流体瞬时释放动力学的影响，以模拟巨烟柱的形成。总的目标是提高对热液喷口动力学的认识，并帮助解释和理解对当地喷口场生态、化学和热通量以及深海环流的观测结果。

This project will conduct laboratory experiments on the dynamics of hydrothermal plumes. The focus will be on the meso-scale flow, where rotation and geostrophic adjustment are important. The first experiment will examine the effects of rotation on the rise height of plumes. The second will study the effects of ambient flows on plume vortex generation. The third will examine the effects of rotation on the dynamics in instantaneous releases of finite volumes of buoyant fluid to simulate megaplume formation. The overall goal is to improve knowledge of the dynamics of hydrothermal venting and to help in the interpretation and understanding of observations of the local vent field ecology, chemical and heat fluxes, as well as deep ocean circulation.
