Description:"Lindsay Werra, a scientist from the University of California Santa Barbara, injects a sample into a gas chromatograph to analyze the sample for methane during a Sept. 2010 mission on board the NOAA Ship Pisces. Researchers use a syringe to extract air -- into which the methane in the water is released -- from the 'head' space (the area of air between the surface of the liquid in the sample container and its seal) and then inject it into the chromatograph, which provides a read out of the amount of methane in the sample. Visit the Pisces online mission log for more details about the voyage. Credit: NOAA"--Deepwater Horizon Response Image Gallery.
