Array of Ocean Bottom Tilt Current Meters: data from the EMSO-Azores observatory, 2022-2023

this dataset contains current data acquired between june 2022 and july 2023 using 5 tcm-3 ocean bottom tilt current meters installed next to the tour eiffel, hydrothermal vent site and near the seamon west station. the tcm-3 ocean bottom tilt current meter from lowell instruments llc (north falmouth, ma, usa) measures current using the drag-tilt principle. the logger is buoyant and is anchored to the bottom via a short flexible tether. drag from moving water tilts the logger in the direction of flow. the logger’s accelerometer and magnetometer channels are used to record the amount of tilt and direction of tilt (compass bearing). the currentmeter's internal clocks are set to utc time before deployment. clock drift after recovery is not implemented in data but added as metadata in the meta data file.data are provided for each deployed instrument as two text files: current data temperature data

本数据集收录了自2022年6月至2023年7月期间收集的数据，这些数据由安装在埃菲尔铁塔附近、海底热液喷口以及西站附近海域的5台TCM-3海底倾斜流速仪所获取。TCM-3海底倾斜流速仪由Lowell Instruments LLC（美国马萨诸塞州北法尔茅斯）生产，其通过拖曳倾斜原理来测量流速。该记录仪具有浮力，并通过一根短而灵活的系绳锚定于海底。流动中的水流产生的拖曳力会使记录仪朝向流速方向倾斜。记录仪的加速度计和磁力计通道被用于记录倾斜量及其倾斜方向（罗盘方位）。在部署前，流速仪的内部时钟被设置为协调世界时（UTC）。数据恢复后的时钟漂移未在数据中体现，但已作为元数据添加至元数据文件中。每个部署的仪器提供两个文本文件的数据：流速数据、温度数据。
