Gas hydrates found at the seafloor on July 11 and July 12 had different forms. On the top image, a small piece of massive gas hydrate formed above leaking methane. In the bottom image, white gas hydrate formed under a rock overhang. Bubbles being emitted from the seafloor are visible in the shadow below the rock. Laser scale denotes 10 centimeters.
