在伍兹霍尔海洋研究所的研究人员进行了几次预期的为期一年的部署之前，作者于 2001 年 1 月 9 日部署了生产型麦克莱恩停泊剖面仪 (MMP)，在夏威夷海脊南翼进行了短期试验。系泊装置位于 2600 米深的水中，MMP 被编程为在 600 分巴至 1600 分巴压力之间连续分析。该系统按照计划完成了 62 个剖面，然后于 2001 年 1 月 13 日恢复。平均剖面持续时间为 75 分钟，在此期间系统记录了电导率、温度、压力、洋流和系统工程信息的完整记录。 MMP 和传感器在试验期间表现良好，为目前正在进行的为期一年的科学部署提供了更大的信心。本文对试验期间收集的工程数据进行了初步分析，并讨论了零压率检测、斯特劳哈尔振荡和功耗。幸运的是，试验期间收集的传感器数据已被证明具有科学价值。特别是，MMP 记录了引人注目的斜压潮汐信号，这些信号可能是夏威夷海脊测深发生的正压潮汐事件的产物。将讨论传感器数据的一部分。
In advance of several anticipated one-year-duration deployments by Woods Hole Oceanographic Institution investigators, the authors deployed a production model McLane Moored Profiler (MMP) on January 9, 2001 for a short-duration trial on the southern flank of the Hawaiian Ridge. The mooring was placed in 2600 meters of water and the MMP was programmed to profile continuously between 600 dbars and 1600 dbars pressure. The system completed 62 profiles, as programmed, before recovery on January 13, 2001. The average profile duration was 75 minutes, during which the system logged a complete record of conductivity, temperature, pressure, ocean current, and system engineering information. The MMP and the sensors performed well during the trial, providing greater confidence for the year-long scientific deployments now being conducted. A preliminary analysis of the engineering data gathered during the trial is presented here with discussions of zero-pressure rate detection, Strouhal oscillation, and power consumption. Fortuitously, the sensor data collected during the trial have proven to be scientifically valuable. In particular, the MMP documented striking baroclinic tidal signals that are likely the product of the barotropic tide incident on the bathymetry of the Hawaiian Ridge. A portion of the sensor data will be discussed.
