AUV raw and vehicle-corrected track line navigation and magnetic field data for the HD-YLAKE project, Yellowstone Lake, 2016

This data set consists of raw and vehicle corrected trackline navigation and magnetic field measurements collected by an autonomous underwater vehicle (AUV) in Yellowstone Lake in July 2016. The AUV magnetometer was an APS (Applied Physics Systems model 1540) 3-axis fluxgate sensor (https://www.appliedphysics.com/products/magnetometers/) as part of a Self-Compensating Magnetometer (SCM) System supplied by Ocean Floor Geophysics Inc. (OFG: https://www.oceanfloorgeophysics.com). The WHOI REMUS group operated the REMUS 600 AUV. Navigation was provided by a deployed acoustic transponder network. The data files are in ASCII format with the following columns: unix time in seconds, year, month, day, hour, min, sec, longitude, latitude, heading (degrees), depth (meters), altitude (meters), pitch (degrees), roll (degrees), mag1 (nT), mag2 (nT), mag3 (nT), total magnetic field intensity (nT), thrust (amps), fiducial, mag1_corrected (nT), mag2_corrected (nT), mag3_corrected (nT), corrected total magnetic field intensity (nT), uncorrected total magnetic field intensity (nT), total field correction (nT). The file names are formatted with the AUV dive name as the first part of the file name followed by the name of the dive used for the magnetic calibration. In this survey, the magnetic calibration factors for all of the files are based on data from dive YL16A06. The lake surface and AUV magnetic data sets were acquired under National Park Service research permit YELL-2016-SCI-7018. The data set was generated as part of the Hydrothermal Dynamics of Yellowstone Lake (HD-YLAKE) project and was supported by National Science Foundation grant EAR-1516361.
