Joyce 9215342 An observational program of moored acoustic Doppler current profilers and current meters will be conducted under the RIDGE program to examine the spatial and temporal variability of a buoyant hydrothermal plume on the Cleft segment of the Juan de Fuca Ridge. The objectives are to determine if the observed features of velocity and vorticity fields are consistent with the theory that suggest that hydrothermal venting can generate unsteady mesoscale vortices and whether they are correlated with anomalous temperature and particulate signatures associated with the venting.

乔伊斯9215342 将在海脊方案下实施一个系泊声学多普勒海流剖面仪和海流计观测方案，以研究胡安·德富卡海脊裂缝段上浮力热液羽流的空间和时间变化。目的是确定所观察到的速度和涡度场的特征是否与热液喷口可以产生不稳定的中尺度涡的理论相一致，以及它们是否与异常温度和与喷口相关的颗粒特征相关。
