Controlled-source electromagnetic data from the TAG hydrothermal field, 26N Mid-Atlantic Ridge

Raw data from electromagnetic survey at the Mid-Atlantic Ridge 26N (JC138, cruise report https://www.bodc.ac.uk/resources/inventories/cruise_inventory/report/16052/ ) , July 2016. Vulcan voltage logger binary files (Constable, S. et al. 2016, Scripps Institution of Oceanography) and DASI electric current transmitter .tdms files (Sinha et al. 1990, University of Southampton) can be read with the Matlab scripts attached (scripts to read Vulcan data are also found at http://marineemlab.ucsd.edu/Projects/lcplot/). Navigation files include CTD measurements at DASI, pressure at each instrument, USBL data for DASI and the end of the array, winch/deep tow cable data, and internal compass readings for the towed Vulcan receivers, some of which are .mat files that can be read with Matlab.2016年7月大西洋中脊26°N海域电磁探测原始数据（航次编号JC138，航次报告链接：https://www.bodc.ac.uk/resources/inventories/cruise_inventory/report/16052/）。本次数据集包含Vulcan电压记录仪二进制文件（Constable S等，2016，斯克里普斯海洋研究所）与DASI电流发射机.tdms格式文件（Sinha等，1990，南安普顿大学），可通过附件中的Matlab脚本读取（读取Vulcan数据的脚本亦可从http://marineemlab.ucsd.edu/Projects/lcplot/ 获取）。导航文件涵盖DASI站位的CTD（温盐深，Conductivity-Temperature-Depth）测量数据、各仪器的压力数据、DASI及探测阵列末端的超短基线（USBL）数据、绞车/深拖缆数据，以及拖曳式Vulcan接收器的内置罗盘读数；其中部分文件为.mat格式，可通过Matlab读取。
