Experimental Studies of Hydrothermal Plume Dynamics

该项目将对以下方面的动力学进行实验室实验： 热液羽流 重点将放在中尺度流动上， 旋转和地转调整是重要的。 第一 实验将检验旋转对上升高度的影响 羽毛。 第二部分将研究环境气流对 羽流涡流生成 第三部分将研究 旋转对瞬时释放动力学的影响 大量的浮力流体来模拟巨型羽流的形成。 的 总的目标是提高知识的动态 热液喷发，并帮助解释， 了解对当地喷口区生态的观察， 化学和热通量以及深海环流。

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.
