Lipid content and stable isotopes of zooplankton during five winters around the northern Antarctic Peninsula
The Southern Ocean zooplankton community is diverse, yet most species are understudied, especially with respect to their overwinter feeding ecologies. This dataset describes body condition and trophic biomarker data (lipid content and stable isotopes of carbon and nitrogen) from 19 zooplankton speci...

The Southern Ocean zooplankton community is diverse, yet most species are understudied, especially with respect to their overwinter feeding ecologies. This dataset describes body condition and trophic biomarker data (lipid content and stable isotopes of carbon and nitrogen) from 19 zooplankton species collected over five consecutive winters (August and September 2012 – 2016) around the northern Antarctic Peninsula.
