Stable isotope data of two benthic invertebrates and environmental variables from Marian and Sheldon Coves (Western Antarctic Peninsula)

This database includes stable isotope (δ¹³C, δ¹⁵N, δ³⁴S) and C:N ratios from the Antarctic benthic invertebrates «Nuculana inaequisculpta» and «Edwardsia» sp. collected across glacier-influenced fjords of the Western Antarctic Peninsula. The dataset also contains associated environmental variables used for ecological analyses. These data will form part of an upcoming scientific publication.
