Lake surface magnetic anomaly data (netCDF format) for the HD-YLAKE project, Yellowstone Lake
This data set consists of a merged grid of magnetic field anomaly over northern Yellowstone Lake and adjacent area from three surveys draped over topography and the lake surface with a grid spacing of 25 m. To compute this grid the measured data values were reduced to the level of the lake surface (2358 m) and topography surrounding the lake. The file is in GMT-compatible netCDF grid format. The combined data sets consist of a 2016 lake level magnetic survey, a 2016 a low-altitude aeromagnetic survey collected by USGS [Finn et al., 2020] and a regional higher altitude aeromagnetic survey collected by USGS in 1997 [U.S. Geological Survey, 2000; Finn and Morgan, 2002]. Details of the grid merging and analysis procedures 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 and the 2016 aeromagnetic data was collected under research permit YELL-2016-SCI-7056.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.
