Alkanoic acid composition of marine and terrestrial sedimentary archives from sub-Antarctic South Georgia ...
The dataset comprises alkanoic acids composition data that was obtained on sediment samples from sub-Antarctic South Georgia. The sediments were collected from a range of different sites, including lakes, peat deposits, a marine inlet and a fjord during RV Polarstern expedition PS81 in 2013. Prior t...
