Black and white seafloor photomosaic of the Lucky Strike hydrothermal field, acquired with VICTOR6000 during the MOMAR2008-Leg-1 cruise. Individual still images were matched, corrected for uneven illumination, renavigated and blended for a seamless photomosaic.  This data release includes partial geotiffs covering the whole surveyed area. These data were published by Barreyre et al. (2012) and Escartin et al. (2013) (see references).
