"With advanced multibeamsonar, it may become routine to discover seeps while we systematically explore our poorly known ocean, " NOAA scientist Stephen Hammond said in the statement.
The NOAA ship Okeanos Explorer mapped the locations between Nov. 2 and Nov. 20 using multibeamsonar, which produces detailed images of the seafloor by calculating the amount of time and distance it takes for sound waves to travel from the ship to the seafloor and back.
