Lake surface magnetic observation level grid (netCDF format) for the HD-YLAKE project, Yellowstone Lake

This data set consists of a digital elevation grid (topography and lake level) of the merged magnetic observation level over northern Yellowstone Lake and adjacent area in meters above sea level with a grid spacing of 25m. The grid is in GMT-compatible netCDF grid format and represents the observation level of the related lake surface magnetic anomaly grid including the lake level and surrounding terrain. Details of the grid 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 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.
