Methane Plumes Map (IMAGE)
Caption
This map of Puget Sound shows the location of the methane plumes (yellow and white circles) detected along the ship’s path (purple). Black lines show the South Whidbey Island Fault Zone, the Seattle Fault Zone and the Tacoma Fault Zone. Black squares are urban sewer outfalls, which don’t match the bubble plumes’ locations.
