Clague, David, et al., (2022), Preliminary 1-meter resolution bathymetric model (GeoTIFF image format) for the distal South Rift Zone region of Axial Seamount, version as of 31 October 2019. Marine Geoscience Data System (MGDS). doi:10.26022/IEDA/330467

This data set (investigators D. W. Caress, D. A. Clague, J. B. Paduan, M. Le Saout) is compiled from data collected on surveys of the South Rift Zone at Axial Seamount between 2011 and 2019 by the MBARI Mapping AUVs. This data set is as published in Le Saout et al., 2022, Faulting and magmatic accretion across the overlapping spreading center between Vance Segment and Axial South Rift, GRL. The bathymetry is interim and to be considered a work in progress. The navigation model underlying this version of bathymetry was generated on 31 October 2019 using the MB-System mbnavadjust program, with which the AUV surveys are tied together. As future data are acquired, the bathymetry coverage will increase and the navigation model will shift. This raster data file is in GeoTIFF image format in the geographic WGS-1984 coordinate system and has 1-m horizontal resolution, with square cells for use with GIS. The GeoTIFF image is slope-shaded using the Haxby color ramp with the depth range that was used in Figure 1 of LeSaout et al., 2021: -2600 to -2000 meters. Funding for the work was provided through annual grants to MBARI from the David and Lucile Packard Foundation.
