Video footage captured by the Little Hercules ROV and camera platform during the April 21 ROV dive from NOAA Ship Okeanos Explorer during the Gulf of Mexico Expedition 2012. The dive was conducted in Green Canyon lease block 470 and operations were concentrated around the top of a topographic high – perhaps the crest of a surfacing salt dome. A predominantly extinct brine pool and many small drainage channels were observed during the dive, presumably the remnants of old brine flow features. Small amounts of brine were also observed, including drainage channels filled with brine feeding a small pool.
