Inhaltsangabe:
- Shallow sediment cores were collected with Push Cores deployed with the ROV MARUM-SQUID at locations on the shelf and slope of South Georgia during cruise M134/1 with R/V METEOR in 2017. In order to determine distributions of methane and characterize biogeochemical zonations in the sediment, 3 mL of the sediment was removed from the cores at defined depths using cut-off syringes and transferred to 20 mL glass vials filled with 5 ml NaOH solution to generate a 12 mL headspace gas volume. The headspace gas samples were analyzed for their methane concentrations by use of a gas chromatograph equipped with a capillary column and a flame ionization detector.
