Seasonal plankton δ13C and δ15N in the Subantarctic

This dataset comprises measurements of δ13C and δ15N for both SPM and mesozooplankton collected within the Indian sector of the Southern Ocean, particularly from the Subantarctic Zone (SAZ) and the Polar Frontal Zone (PFZ). The collection was conducted aboard the MV S.A. Agulhas II during two autumn cruises in April-May of 2016 and 2017, and during two winter cruises in July-August 2015 and June-July 2017, as well as aboard the MV Akademik Treshnikov during the Antarctic Circumnavigation Expedition (ACE) in early summer of December 2016. Mesozooplankton data are available only for the two autumn seasons and the summer of 2016.
