Stable isotope ratios of Antarctic echinoids from the PS81 - ANTXXIX/3 Polarstern expedition

This dataset contains carbon and nitrogen stable isotope
composition of 120 Antarctic sea urchins belonging to 10 taxa (Abatus
cavernosus, Amphipneustes rostratus, Amphipneustes
similis, Aporocidaris eltaniana, Brachyternaster
chesheri, Ctenocidaris gigantea, Notocidaris gaussiensis, Notocidaris
mortenseni, Sterechinus antarcticus and Sterechinus neumayeri) and
sampled in Drake Passage, Bransfield Strait and Weddell Sea during the
ANTXXIX/3 (PS81) cruise of RV Polarstern in 2013.

This data supports the article "Trophic Plasticity of
Antarctic echinoids under contrasted environmental conditions" by L.N.
Michel, B. David, P. Dubois, G. Lepoint & C. De Ridder, published in Polar
Biology (doi: 10.1007/s00300-015-1873-y).
