Data from: Assessing stable isotope dynamics of diapausing Calanus finmarchicus and C. hyperboreus during the overwintering period: a laboratory experiment
This study aimed at describing changes in the stable isotopic composition of late copepodite stage V (CV) subarctic marine copepods (Calanus finmarchicus and C. hyperboreus) during overwintering non-feeding periods. Diapausing stage CVs sampled in deep waters of the Lower St. Lawrence Estuary (Québe...

This study aimed at describing changes in the stable isotopic composition of late copepodite stage V (CV) subarctic marine copepods (Calanus finmarchicus and C. hyperboreus) during overwintering non-feeding periods.
