We release images of the submarine bottom from the northern sector of the Golfo San Jorge, withinthe Southern Patagonia Coastal Marine Interjurisdictional Park (PIMCPA for its initials in Spanish). The images were obtained through a high-resolution multi-beam echo sounder Kongsberg Maritime EM 2040 during the 2014 oceanographic campaign of the R/V Coriolis II in the framework of the MARGES project. The digital data of the echo sounder are in the processing stage. The images illustrated here are screenshots of sectors that were of interest because of the inhomogeneity of the sea bottom due to the presence of "hard" rock outcrops, which can be distinguished as they emerge above the sedimentary bottom with a generally flat to sub-undulated topography.
