Details of reflectors compatible with lenses (A) and solid bands (B), recorded with sea-bottom portable profiler (EdgeTech Discover SB-3200-XS), in a sector of marine substrate, up to 210 m depth below seabed (bsb), towards the NE of Bouchard zone (Figure 1). These reflectors may correspond to methane accumulations, frozen in the marine substrate at the surroundings of Seymour (Marambio) Island. Latitude, longitude, and depth indicated below correspond to the one at the middle point of each graph.
