Data from: Tracing the origins of Calanus sp. in the Saguenay‑St. Lawrence Marine Park (Québec, Canada) using δ13C as a marker
The Saguenay-St. Lawrence Marine Park (SSLMP) is a region that sustains a high abundance of zooplankton. The connectivity between zooplankton populations within the SSLMP and the surrounding areas was investigated for Calanus finmarchicus and C. hyperboreus. Deep-dwelling stage V copepodites (CVs) w...
