GeoTIFF images of gridded near-bottom bathymetry from the north rift zone of Axial Seamount (2016 RCSN392 survey)

These GeoTIFF rasters have the color ramps used in Figure 2 of LeSaout et al. (2020), plus a color ramp that spans the analyzed area. The images are all slope-shaded, hence "slope" in the file names. The depth range, in meters, of the Haxby color ramp used in each of the images is the final part of the filename. These GeoTIFF images were made from a grid of 1-m lateral resolution processed swath bathymetry compiled from MBARI Mapping AUV data acquired on the north rift zone of Axial Seamount with a Reson SeaBat 7125 multibeam sonar system in the summer of 2016 during R/V Rachel Carson cruise RCSN392. The data files are in GeoTIFF grid image format and were generated with several color ramps as indicated by the depth ranges in the file names. The files are in WGS-1984 geographic coordinates, as square cells for use with GIS. Navigation is DVL/USBL, adjusted with MBSystem in post-processing. The AUV navigation adjustment model is consistent with the shapefile of 2015 lava flow boundaries of DOI 10.1594/IEDA/324417 (which is also used in the Le Saout et al. 2020 paper). The files are a subset of the data collected as part of the 2016 Northern Expedition to Axial Seamount. Funding for the work was provided with a grant to MBARI from the David and Lucile Packard Foundation.
