Title:

Processed AUV magnetic anomaly and corrected vehicle navigation data for the HD-YLAKE project, Yellowstone Lake, 2016

Abstract:

This data set consists of processed track line navigation and magnetic field measurements collected by an autonomous underwater vehicle (AUV) in Yellowstone Lake in July 2016 by Ocean Floor Geophysics Inc. (OFG) (https://www.oceanfloorgeophysics.com/). Diurnal corrections to the magnetic data were applied utilizing the Newport (NEW) and Boulder (BOU) geomagnetic observatory records. The regional IGRF magnetic field [Thebault et al., 2015] was removed to produce the anomaly. Navigation was provided by a deployed acoustic transponder network. Data processing of the navigation data included masking of AUV maneuvers and jumps in the data, correction of a residual heading effect and separation of the data acquired at the 15-m height above lake bed from a 7-m height above lake bed. Details of the processing are explained in Bouligand et al., 2020. The data files are in ASCII format with the following columns: longitude, latitude, UTM x (m), UTM y (m), depth(m), height above lake floor (m), magnetic anomaly (nT). 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.
