Hannah Liddy (Organic Geochemist, University of Southern California, USA) extracts a piece of sediment from the end of a core section on the catwalk. The “headspace gas” sample is heated in an oven, which drives off gases trapped in the sediment. These gases are collected and analyzed in a gas chromatograph to determine their composition.
