Deep Arctic Ocean Methane Seeps 3 (image) CAGE - Center for Arctic Gas Hydrate, Climate and Environment Share Print E-Mail Caption Arctic seafloor at 500 meters water depth. Carbonate blocks are colonized by anemones and sponges. Tube worms are abundant at the seafloor. In the upper part of the image, we see patches of bacterial mats. All of these features are indigenous to sites of methane release. Schools of codfish appeared to be following the laser beams from the camera system. Fish were often observed in big quantities during the cruise.
