Methane concentrations (uncorrected for sediment porosity and Bunsen coefficient) in headspace gas prepared from gravity core GeoB22039-2 recovered from the Royal Trough, South Georgia (cruise M134)

Gravity cores were collected during cruise M134 in 2017 from the Royal Trough and the Cumberland Bay, off South Georgia. In order to determine distributions of light hydrocarbons and characterize biogeochemical zonations in the shallow sediments, sediment samples were taken from gravity cores with c...
