CTD and ADCP hydrothermal plume data from the MomarSat 2023 cruise

this dataset contains measurement profiles for 3d velocity, temperature, pressure, and salinity collected above the tour eiffel sulfide structure at the lucky strike hydrothermal site, as well as in areas distant from the vents field. the data was acquired with an ultra-short baseline (usbl) acoustic positioning system, an acoustic doppler current profiler (adcp aquadopp v2.00.02), and a conductivity-temperature-depth (ctd sea-bird sbe 19plus) sonde. an overview of the experimental setup is provided. the ctd instrument was calibrated in october 2021, and the calibration coefficients can be found in a .xmlcon file.the primary objective of this experiment was to measure the characteristics of the hydrothermal plume during the momarsat 2023 cruise. acquisitions were conducted intermittently over a span of 4 days, with a maximum vertical resolution of o(10 m).the data is available in .cnv and .csv file formats, for compatibility with the pandas library in python. usbl data was filtered to retain only the temporal positions (degrees and decimal minutes format). basic post-processing of ctd data was performed using seasave v 7.23.1. data acquisition was conducted in successive vertical steps to align with the adcp acquisition frequency, and adcp data was filtered to keep only the fixed positions.

本数据集收录了在幸运打击海底热液区托尔埃菲尔硫化结构上方及其远离喷口区域采集的3D速度、温度、压力和盐度测量剖面。数据通过超短基线（USBL）声学定位系统、声学多普勒流速剖面仪（ADCP Aquadopp v2.00.02）以及电导率-温度-深度（CTD Sea-Bird SBE 19plus）声纳进行采集。实验装置概览亦附于其中。CTD仪器于2021年10月进行了校准，校准系数可在.xmlcon文件中查得。本实验的主要目标是测量在Momarsat 2023航次期间海底热液羽流的特性。数据采集在为期4天的间歇期内进行，最大垂直分辨率为0（10米）。数据以.cnv和.csv文件格式提供，以兼容Python中的pandas库。USBL数据经过滤波，仅保留时间位置（以度和分数形式表示）。CTD数据的基本后处理使用Seasave v 7.23.1完成。数据采集以连续的垂直步骤进行，以与ADCP采集频率对齐，并滤除ADCP数据中的固定位置。
