Researchers collect methane samples in the ocean (IMAGE)
Caption
Researchers used a giant suction hose to collect thousands of gallons of ocean water, while on the research ship R/V Hugh Sharp. The researchers extracted methane from each sample, compressed the methane into cylinders, and brought the cylinders back to the lab of John Kessler, a professor of earth and environmental sciences at the University of Rochester. They measured unique isotopic “signatures” of oceanic methane in the samples and found that although ancient methane is being released from the seafloor, negligible amounts reach the surface waters and therefore the atmosphere.
