Regional patterns of δ ¹³C and δ ¹⁵N for European common cuttlefish (Sepia officinalis) throughout the Northeast Atlantic Ocean and Mediterranean Sea.

ABSTRACT: Stable isotope compositions of carbon and nitrogen (expressed as δ ¹³C and δ ¹⁵N) from the European common cuttlefish (Sepia officinalis) were measured in order to evaluate the utility of using these natural tracers throughout the Northeast Atlantic Ocean and Mediterranean Sea (NEAO-MS). Mantle tissue was obtained from S. officinalis collected from 11 sampling locations spanning a wide geographical coverage in the NEAO-MS. Significant differences of both δ ¹³C and δ ¹⁵N values were found among S. officinalis samples relative to sampling location. δ ¹³C values did not show any discernable spatial trends; however, a distinct pattern of lower δ ¹⁵N values in the Med
