Organic geochemical characterization on a seal excrement sediment core from Fildes Peninsula, Western Antarctica
Organic geochemical analysis was performed on a sediment core HN1 from Fildes Peninsula on King George Island, Western Antarctica. Short-chain n-alkanes were the main components of the aliphatic hydrocarbons present, and they were likely to be from algae and bacteria; n-C23 was likely derived from m...
