AUV data depth and data height grids for the 7m (10m resolution) files (GXF format) over the Deep Hole hydrothermal site, HD-YLAKE project, Yellowstone Lake
This data set consists of interpolated grids over the Deep Hole hydrothermal site in northern Yellowstone Lake collected in July 2016 by Ocean Floor Geophysics Inc. (OFG) ( The two interpolated grids provide the following: (a) the depth (data depth) below the lake surface (mean lake surface elevation value is 2358m above sea-level) and (b) altitude (data height) above the lake floor of the surface on which the 7m-above-lake-floor magnetic anomaly grid was interpolated. The magnetic field anomalies at approximately 7m above the lake floor are interpolated onto a horizontal grid spacing of 10m. The files are in the Grid eXchange File GXF ASCII grid format. Details of the grid interpolation and analysis are explained in Bouligand et al., 2020. The lake surface and AUV magnetic data sets were acquired under National Park Service research permit YELL-2016-SCI-7018. Maurice Tivey was supported under NSF IPA grant 1557455 to WHOI and WHOI internal funds. During the course of this study, Claire Bouligand was a visiting scientist at the U.S. Geological Survey in Menlo Park, California, USA and benefited from a delegation to Centre National de la Recherche Scientifique (CNRS) and received funding from CNRS-INSU program SYSTER. 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.
Device Info
The data have been processed/modified to a level beyond that of basic quality control (e.g. final processed sonar data, photo-mosaics).
