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 species collected over five consecutive winters (August and
September 2012 – 2016) around the northern Antarctic Peninsula. To
complement these data and provide context for interpretation, we report
environmental data (percent sea-ice cover, sea-ice type, water
temperature, salinity, and integrated chlorophyll-a (to 100 m)) as well as
species abundance data at each sampling location. For most species, these
are the first winter measurements or time series of body condition,
trophic position, and abundance in relation to environmental variables
around the northern Antarctic Peninsula.
